'''Lithuanian''' ({{Langx|lt|label=[[endonym]]|lietuvių kalba}}, {{IPA|lt|lʲiəˈtʊvʲuː kɐɫˈbɐ|pron}}) is an [[East Baltic languages|East Baltic language]] belonging to the [[Baltic languages|Baltic branch]] of the [[Indo-European language family]].

Around half a million inhabitants of Lithuania of non-Lithuanian background speak Lithuanian daily as a second language.

Lithuanian is closely related to neighbouring [[Latvian language|Latvian]], though the two languages are not mutually intelligible. It is written in a [[Latin script]].

There was fascination with the Lithuanian people and their language among the late 19th-century researchers, and the philologist [[Isaac Taylor (priest)|Isaac Taylor]] wrote the following in his ''The Origin of the Aryans'' (1892):
<blockquote>"Thus it would seem that the Lithuanians have the best claim to represent the primitive [[Aryan race]], as their language exhibits fewer of those phonetic changes, and of those grammatical losses which are consequent on the acquirement of a foreign speech."<ref>{{Cite book |last=Taylor |first=Isaac |author-link=Isaac Taylor (priest) |url=https://archive.org/details/cu31924029872847/page/n277/mode/2up |title=The Origin of the Aryans: An Account of the Prehistoric Ethnology and Civilisation of Europe |publisher=24 Warwick Lane, [[Paternoster Row]] |year=1892 |edition=2nd |series=The Contemporary Science |location=London |page=261}}</ref></blockquote>

Lithuanian was studied by several linguists such as [[Franz Bopp]], [[August Schleicher]], [[Adalbert Bezzenberger]], [[Louis Hjelmslev]],<ref>{{Cite book |url=https://books.google.com/books?id=kQ6CTNgAbPMC&q=danis+hjelmslev+studied+lithuanian&pg=PA124 |title=Key Thinkers in Linguistics and the Philosophy of Language |date=2005 |publisher=Oxford University Press |isbn=9780195187687 |editor-last=Chapman |editor-first=Siobhan |page=124 |editor-last2=Routledge |editor-first2=Christopher}}</ref> [[Ferdinand de Saussure]],<ref>{{Cite journal |last=Joseph |first=John E. |date=2009 |title=Why Lithuanian Accentuation Mattered to Saussure |url=http://www.lel.ed.ac.uk/~josephj/LHI_Joseph%5b1%5d.pdf |journal=Language & History |volume=52 |issue=2 |pages=182–198 |doi=10.1179/175975309X452067 |s2cid=144780177 |access-date=1 April 2018 |via=lel.ed.ac.uk}}</ref> [[Winfred P.

By studying place names of Lithuanian origin, linguist {{Ill|Jan Safarewicz|pl}} concluded that the eastern boundaries of Lithuanian used to be in the shape of zigzags through [[Grodno]], [[Shchuchyn]], [[Lida]], [[Valozhyn]], [[Svir, Belarus|Svir]], and [[Braslaw]].<ref name="OriginVle"/> Such eastern boundaries partly coincide with the spread of [[Catholic Church|Catholic]] and [[Orthodoxy|Orthodox]] faith, and should have existed at the time of the [[Christianization of Lithuania]] in 1387 and later.<ref name="OriginVle"/> Safarewicz's eastern boundaries were moved even further to the south and east by other scholars (e.g. {{ill|Mikalay Biryla|be|Мікалай Васілевіч Бірыла}}, {{Ill|Petras Gaučas|lt}}, {{ill|Jerzy Ochmański|pl}}, [[Aleksandras Vanagas]], [[Zigmas Zinkevičius]], and others).<ref name="OriginVle"/>

[[Proto-Balto-Slavic]] branched off directly from Proto-Indo-European, then sub-branched into [[Proto-Baltic]] and [[Proto-Slavic]]. Proto-Baltic branched off into Proto-West Baltic and Proto-East Baltic.<ref name="Smalstieg 1982">{{Cite journal |last=Smalstieg |first=William |date=1982 |title=The Origin of the Lithuanian Language |url=http://www.lituanus.org/1982_1/82_1_01.htm |url-status=dead |journal=Lituanus |volume=28 |issue=1 |archive-url=https://web.archive.org/web/20201111175048/http://www.lituanus.org/1982_1/82_1_01.htm |archive-date=11 November 2020 |access-date=2016-08-07 |via=lituanus.org}}</ref> The Baltic languages passed through a Proto-Balto-Slavic stage, from which the Baltic languages retain exclusive and non-exclusive lexical, morphological, phonological and accentual isoglosses in common with the [[Slavic languages]], which represent their closest living Indo-European relatives. Moreover, with Lithuanian being so archaic in phonology, Slavic words can often be deduced from Lithuanian by regular [[sound law]]s; for example, Lith. ''[[wikt:vilkas#Lithuanian|vilkas]]'' and [[Polish language|Polish]] [[wikt:wilk#Polish|wilk]] ← [[Proto-Balto-Slavic language|PBSl.]] [[wikt:Reconstruction:Proto-Balto-Slavic/wilkás#Proto-Balto-Slavic|*wilkás]] (cf. [[Proto-Slavic language|PSl.]] [[wikt:Reconstruction:Proto-Slavic/vьlkъ#Proto-Slavic|*vьlkъ]]) ← [[Proto-Indo-European language|PIE]] [[wikt:Reconstruction:Proto-Indo-European/wĺ̥kʷos#Proto-Indo-European|*wĺ̥kʷos]], all meaning "[[wolf]]".

Because of the three archaeological cultures in Lithuania, some scholars divide the Lithuanian ethnos into three cultural groups – Samogitians (Western), Aukštaitians{{Efn|In academic literature, they are referred to as ''Aukštaitians'' (a neologism derived from ''Aukštaičiai'') or upland Lithuanians. The translation ''highland Lithuanians'' is not applicable.|name=a}} (Central) and Lithuanians (Eastern). Traditionally, the [[Samogitians|Samogitian]] tribe is included within the broader Lithuanian ethnos as suggested by historical accounts, dividing Lithuania into two parts – ''Austechia'' ([[Aukštaitija]]) and ''Samogitia'' ([[Samogitia|Žemaitija]])<ref>[[Tomas Baranauskas|Baranauskas, Tomas]] (2006). ''Aukštaitija XIII–XV amžiuje'' [''Aukštaitija in the 13th–15th centuries''] (in Lithuanian). Kaunas: Žiemgalos leidykla. p. 1.</ref><ref>Misiūnas, Romuald J., Bater, James H. ''Prehistory to the 18th Century. Baltic states''. [[Encyclopædia Britannica|Encyclopaedia Britannica]].</ref> – but their origins are a subject of ongoing debates. Linguist Jūratė Sofija Laučiūtė argues that prior to their [[Assimilation (phonology)|assimilation]], ancient Samogitians were a different tribe from the [[Lithuanians (tribe)|Lithuanians]], which is evinced by certain linguistic features not explainable by [[phonetics]] alone, such as the ending ''-ou <*-ou'' of masculine [[noun]]s in [[Genitive case|genitive form]] (e.g. [[Samogitian language|Samogitian]] ''velkou'', Lithuanian ''vilkui'', meaning ([[Dative case|{{sc|'''dat'''}}]]) 'wolf'). Valdemaras Šimėnas suggests that both culturally and linguistically ancient Samogitians were closer to [[Curonians]], [[Semigallians]] and [[Selonians]] than Lithuanians.<ref>Kavaliauskas, Antanas (1 January 2018).

Initially, Lithuanian was a [[spoken language]] in the [[Grand Duchy of Lithuania]] and [[Duchy of Prussia]], while the beginning of Lithuanian writing is possibly associated with the introduction of [[Catholic Church in Lithuania|Christianity in Lithuania]] when [[Mindaugas]] was [[Baptism|baptized]] and crowned King of Lithuania in 1250–1251.<ref name="RasomojiKalbaVle">{{cite web |last1=Zinkevičius |first1=Zigmas |title=Lietuvių rašomoji kalba |url=https://www.vle.lt/straipsnis/lietuviu-rasomoji-kalba/ |website=Visuotinė lietuvių enciklopedija |access-date=15 January 2023 |language=lt}}</ref><ref name="OriginVle"/> It is believed that [[prayer]]s were translated into the local dialect of Lithuanian by [[Franciscans|Franciscan]] monks during the baptism of Mindaugas, however none of the writings has survived.<ref name="RasomojiKalbaVle"/> The first recorded Lithuanian word, reported to have been said on 24 December 1207 from the chronicle of [[Henry of Latvia]], was ''Ba'', an [[interjection]] of a Lithuanian raider after he found no loot to pillage in a Livonian church.<ref>{{cite book |last1=Antanavičius |first1=Darius |last2=Baronas |first2=Darius |last3=Dubonis |first3=Artūras |last4=Petrauskas |first4=Rimvydas |title=Mindaugo knyga.

An attempt to reconcile the opposing stances was made by [[Jan Michał Rozwadowski]].<ref name="FoundationsBook"/> He proposed that the two language groups were indeed a unity after the division of Indo-European, but also suggested that after the two had divided into separate entities (Baltic and Slavic), they had posterior contact.<ref name="FoundationsBook"/> The genetic kinship view is augmented by the fact that Proto-Balto-Slavic is easily reconstructible with important proofs in historic prosody. The alleged (or certain, as certain as historical linguistics can be) similarities due to contact are seen in such phenomena as the existence of definite adjectives formed by the addition of an inflected pronoun (descended from the same Proto-Indo-European pronoun), which exist in both Baltic and Slavic yet nowhere else in the Indo-European family (languages such as Albanian and the [[Germanic languages]] developed definite adjectives independently), and that is not reconstructible for Proto-Balto-Slavic, meaning that they most probably developed through language contact.{{sfnp|Zinkevičius|1984|pp=117–138, 209–210}}

As a result of a decrease in the usage of spoken Lithuanian in the eastern part of Lithuania proper, in the 19th century, it was suggested to create a standardized Lithuanian based on the Samogitian dialect.<ref name="BendrineVle"/> Nevertheless, it was not accomplished because everyone offered their Samogitian subdialects and the Eastern and Western Aukštaitians offered their Aukštaitian subdialects.<ref name="BendrineVle"/>

In the second half of the 19th century, when the [[Lithuanian National Revival]] intensified, and the preparations to publish a Lithuanian periodical press were taking place, the mostly south-western Aukštaitian revival writers did not use the 19th-century Lithuanian of Lithuania Minor as it was largely [[Germanisation|Germanized]].<ref name="BendrineVle"/> Instead, they used a more pure Lithuanian language which has been described by [[August Schleicher]] and [[Friedrich Kurschat]] and this way the written language of Lithuania Minor was transferred to resurgent Lithuania.<ref name="BendrineVle"/> The most famous standardizer of the Lithuanian, [[Jonas Jablonskis]], established the south-western Aukštaitian dialect, including the Eastern dialect of Lithuania Minor, as the basis of standardized Lithuanian in the 20th century, which led to him being [[nickname]]d the father of standardized Lithuanian.<ref name="BendrineVle"/><ref name="JablonskisVle"/>

According to Polish professor [[Jan Otrębski]]'s article published in 1931, the Polish dialect in the [[Vilnius Region]] and in the northeastern areas in general are very interesting variant of the Polish language as this dialect developed in a foreign territory which was mostly inhabited by the Lithuanians who were [[Belarusization|Belarusized]] (mostly) or Polonized, and to prove this Otrębski provided examples of Lithuanianisms in the [[Tutejszy#Language|Tutejszy language]].<ref>{{cite book |last1=Nitsch |first1=Kazimierz |last2=Otrębski |first2=Jan |title=Język Polski. 1931, nr 3 (maj/czerwiec) |date=1931 |pages=80–85 |url=http://mbc.malopolska.pl/dlibra/plain-content?id=15400 |access-date=3 November 2023 |publisher=Polska Akademia Umiejętności, Komisja Języka Polskiego |language=pl}}</ref><ref>{{cite web |last1=Martinkėnas |first1=Vincas |title= Vilniaus ir jo apylinkių čiabuviai |url=https://alkas.lt/2016/12/19/is-rytu-lietuvos-lenkinimo-istorijos-vincas-martinkenas-vilniaus-ir-jo-apylinkiu-ciabuviai/ |website=Alkas.lt |access-date=3 November 2023 |language=lt |date=19 December 2016}}</ref> In 2015, Polish linguist {{ill|Mirosław Jankowiak|pl}} attested that many of the Vilnius Region's inhabitants who declare [[Poles in Lithuania|Polish nationality]] speak a Belarusian dialect which they call ''mowa prosta'' ('[[simple speech]]').<ref>{{Cite web|last1=Jankowiak |first1=Miroslaw|url=http://zw.lt/opinie/jankowiak-mowa-prosta-jest-dla-mnie-synonimem-gwary-bialoruskiej/|title="Mowa prosta" jest dla mnie synonimem gwary białoruskiej|date = 26 August 2015|access-date=3 November 2023|language=pl}}</ref>

Lithuanian uses the [[Latin script]] supplemented with [[diacritic]]s. It has 32 [[Letter (alphabet)|letters]]. In the [[collation]] order, ''y'' follows immediately after ''į'' (called ''i [[ogonek|nosinė]]''), because both ''y'' and ''į'' represent the same long vowel {{IPAblink|iː}}:<ref>{{cite web |title=Lietuvių kalbos abėcėlė |url=http://xn--lietuvyb-ceb.lt/standartai/lietuvi%C5%B3-kalbos-ab%C4%97c%C4%97l%C4%97/ |website=Lietuvybė.lt |access-date=15 January 2023 |language=lt}}</ref>

In addition, the following digraphs are used, but are treated as sequences of two letters for collation purposes. The digraph ''ch'' represents a single sound, the velar fricative {{IPAblink|x}}, while ''dz'' and ''dž'' are pronounced like straightforward combinations of their component letters (sounds):

Dz dz {{IPAblink|dz}} (dzė), Dž dž {{IPAblink|dʒ}} (džė), Ch ch {{IPAblink|x}} (cha).

The distinctive Lithuanian letter ''[[Ė]]'' was used for the first time in the [[Daniel Klein (grammarian)|Daniel Klein]]'s ''[[Grammatica Litvanica]]'' and firmly established itself in Lithuanian since then.<ref name="MilinieneVe">{{cite web |last1=Milinienė |first1=Audronė |last2=Subačius |first2=Giedrius |title=Kas išrado raidę Ė? |trans-title=Who invented the letter Ė? |url=https://ve.lt/naujienos/lietuva/lietuvos-naujienos/kas-isrado-raide-e-1583724 |website=Ve.lt |access-date=16 January 2023 |language=lt |date=30 September 2017}}</ref><ref>{{cite web |last1=Gedutienė |first1=Audronė |title=Danieliaus Kleino knyga |trans-title=Daniel Klein's book |url=https://maironiomuziejus.lt/post-t-exhibit/danieliaus-kleino-knyga/ |website=Maironiomuziejus.lt |access-date=16 January 2023 |language=lt}}</ref>{{sfn|Subačius|2005|p=9}}<ref>{{cite web |title=Seniausia unikali lietuvių kalbos raidė |trans-title=The oldest unique letter of Lithuanian |url=https://rekordai.lt/rekordai/seniausia-unikali-lietuviu-kalbos-raide/ |website=Records of Lithuania |access-date=16 January 2023 |language=lt}}</ref> However, linguist [[August Schleicher]] used ''Ë'' (with two points above it) instead of ''Ė'' for expressing the same.<ref name="Subacius2019">{{cite web |last1=Antanavičius |first1=Ugnius |title=Pokalbis su filologu G.Subačiumi: kaip atsirado bendrinė lietuvių kalba ir kodėl turime Ė, bet praradome W? |url=https://www.15min.lt/gyvenimas/naujiena/ar-zinai/pokalbis-su-filologu-g-subaciumi-kaip-atsirado-bendrine-lietuviu-kalba-ir-kodel-turime-e-bet-praradome-w-1634-1192962 |website=[[15min.lt]] |access-date=16 January 2023 |language=lt}}</ref> In the ''Grammatica Litvanica'' Klein also established the letter ''[[W]]'' for marking the sound [v], the use of which was later abolished in Lithuanian (it was replaced with ''V'', notably by authors of the ''[[Varpas]]'' newspaper).<ref name="MilinieneVe"/><ref name="Subacius2019"/>{{sfn|Venckienė|2017|p=16-20}} The usage of ''V'' instead of ''W'' especially increased since the early 20th century, likely considerably influenced by Lithuanian press and schools.{{sfn|Venckienė|2017|p=16-20}}

The Lithuanian writing system is largely phonemic, i.e., one letter usually corresponds to a single [[phoneme]] (sound). There are a few exceptions: for example, the letter ''i'' represents either the vowel {{IPAblink|ɪ}}, as in English ''sit'', or is silent and merely indicates that the preceding consonant is [[Palatalization (phonetics)|palatalized]]. The latter is largely the case when ''i'' occurs after a consonant and is followed by a [[Back vowel|back]] or a [[central vowel]], except in some borrowed words (e.g., the first consonant in ''lūpa'' {{IPA|[ˈ'''ɫ'''ûːpɐ]}}, "lip", is a [[Velarized alveolar lateral approximant|velarized dental lateral approximant]]; on the other hand, the first consonant in ''liūtas'' {{IPA|[ˈ'''lʲ'''uːt̪ɐs̪]}}, "lion", is a palatalized [[alveolar lateral approximant]]; both consonants are followed by the same vowel, the long {{IPAblink|uː}}, and no {{IPAblink|ɪ}} can be pronounced in ''liūtas'').

Due to [[Polonization|Polish influence]], the Lithuanian alphabet included ''[[Sz (digraph)|sz]]'', ''[[Cz (digraph)|cz]]'' and the Polish ''[[Ł]]'' for the first sound and regular L (without a following i) for the second: ''łupa'', ''lutas''.{{sfn|Subačius|2005|p=9}} During the [[Lithuanian National Revival]] in the 19th century the Polish ''Ł'' was abolished, while [[Digraph (orthography)|digraphs]] ''sz'', ''cz'' (that are also common in the [[Polish orthography]]) were replaced with ''[[š]]'' and ''[[č]]'' from the [[Czech orthography]] because formally they were shorter.{{sfn|Subačius|2005|p=9}}<ref name="Subacius2019"/>{{sfn|Venckienė|2017|p=20-25}} Nevertheless, another argument to abolish ''sz'' and ''cz'' was to distinguish Lithuanian from [[Polish language|Polish]].<ref name="Subacius2019"/> The new letters ''š'' and ''č'' were cautiously used in publications intended for more educated readers (e.g. ''Varpas'', ''[[Tėvynės sargas]]'', ''[[Ūkininkas]]''), however ''sz'' and ''cz'' continued to be in use in publications intended for less educated readers as they caused tension in society and prevailed only after 1906.{{sfn|Venckienė|2017|p=20-23}}<ref>{{cite journal |last1=Venckienė |first1=Jurgita |title=Dvejopa XIX a. pabaigos lietuviškų laikraščių rašyba |journal=Raidžių draudimo metai |date=2004 |location=Vilnius |publisher=Lithuanian Institute of History Press |pages=207–213}}</ref>

The Lithuanians also adopted the letter ''[[ž]]'' from the Czechs.{{sfn|Subačius|2005|p=9}}

The [[nasal vowel]]s ''[[ą]]'' and ''[[ę]]'' were taken from the Polish spelling and began to be used by [[Renaissance]] [[Lithuanian literature|Lithuanian writers]], later the Lithuanians introduced the nasal vowels ''[[į]]'' and ''[[ų]]'' as analogues.{{sfn|Subačius|2005|p=9}}<ref name="Subacius2019"/> The letter ''[[ū]]'' is the latest addition by linguist [[Jonas Jablonskis]].{{sfn|Subačius|2005|p=9-10}}<ref name="Subacius2019"/>

A [[Macron (diacritic)|macron]] (on ''u''), an [[ogonek]] (on ''a'', ''e'', ''i'', and ''u''), a [[Dot (diacritic)|dot]] (on ''e''), and ''y'' (in place of ''i'') are used for grammatical and historical reasons and always denote [[vowel length]] in Modern Standard Lithuanian. [[Acute accent|Acute]], [[Grave accent|grave]], and [[tilde]] diacritics are used to indicate [[pitch accent]]s. However, these pitch accents are generally not written, except in dictionaries, grammars, and where needed for clarity, such as to differentiate homonyms and dialectal use.

All Lithuanian consonants except {{IPA|/j/}} have two variants: one non-[[Palatalization (phonetics)|palatalized]] and one palatalized, for example, {{IPA|/b/}}&nbsp;– {{IPA|/bʲ/}}, {{IPA|/d/}}&nbsp;– {{IPA|/dʲ/}}, {{IPA|/ɡ/}}&nbsp;– {{IPA|/ɡʲ/}} (see the chart above for the full consonant set, represented by [[International Phonetic Alphabet|IPA]] symbols). The consonants {{IPA|/f/}}, {{IPA|/x/}}, {{IPA|/ɣ/}} and their palatalized counterparts are only found in [[loanword]]s.

{{IPA|/t͡ɕ, d͡ʑ, ɕ, ʑ/}} have been traditionally transcribed with {{angbr IPA|t͡ʃʲ, d͡ʒʲ, ʃʲ, ʒʲ}}, but they can be seen as equivalent transcriptions, with the former set being somewhat easier to write.<ref>{{Harvcoltxt|Ladefoged|Maddieson|1996|p=?}}</ref>

===Vowels===

Lithuanian has six long vowels and four short ones (not including disputed phonemes marked in brackets). Length has traditionally been considered the distinctive feature, though short vowels are also more centralized and long vowels more peripheral:

* {{IPA|/e, ɔ/}} are restricted to loanwords. Many speakers merge the former with {{IPA|/ɛ/}}.{{sfnp|Ambrazas et al.|1997|p=24}}

===Diphthongs===
Lithuanian is traditionally described as having nine [[diphthong]]s, ''ai'','' au'','' ei'','' eu'','' oi'','' ou'','' ui'','' ie'', and'' uo.'' However, some approaches (i.e., Schmalstieg 1982) treat them as vowel sequences rather than diphthongs; indeed, the longer component depends on the type of stress, whereas in diphthongs, the longer segment is fixed.

===Pitch accent===
{{Main|Lithuanian accentuation}}
The Lithuanian prosodic system is characterized by free accent and distinctive quantity (i.e. [[syllable weight]]). The word prosody of Lithuanian is sometimes described as a restricted [[tone (linguistics)|tone]] system, also called a [[pitch accent]] system.<ref name="tone">{{Cite conference |last1=Dogil |first1=Grzegorz |last2=Möhler |first2=Gregor |date=1998 |title=Phonetic Invariance and Phonological Stability: Lithuanian Pitch Accents |url=https://www.isca-speech.org/archive/icslp_1998/i98_0206.html |conference=5th International Conference on Spoken Language Processing, Sydney, Australia, November 30 – December 4, 1998 |access-date=27 May 2021 |archive-date=2 August 2021 |archive-url=https://web.archive.org/web/20210802002227/https://www.isca-speech.org/archive/icslp_1998/i98_0206.html |url-status=dead}}</ref> In Lithuanian, [[lexical word]]s contain a single syllable that is prominent or stressed. Among those, [[heavy syllable]]s – that is, those containing a [[long vowel]], [[diphthong]], or a [[sonorant]] coda – bear either one of two tones: a falling (or ''acute tone'') or a rising (or ''circumflex tone''). Light syllables (syllables with short vowels and optionally also [[obstruent]] codas) do not have the two-way contrast of heavy syllables.

Lithuanian is a highly [[inflected language]]. In Lithuanian, there are two [[grammatical gender]]s for nouns (masculine and feminine) and three genders for adjectives, pronouns, numerals and participles (masculine, feminine and neuter). Every attribute must agree with the gender and number of the noun. The neuter forms of other parts of speech are used with a [[Subject (grammar)|subject]] of an undefined gender (a pronoun, an infinitive etc.).

There are twelve [[noun]] and five [[adjective]] [[declension]]s and one (masculine and feminine) participle declension.<ref>{{Cite book |title=Dabartinės lietuvių kalbos gramatika |date=1997 |location=Vilnius |language=lt |trans-title=A Grammar of Modern Lithuanian}}</ref>

Nouns and other parts of nominal morphology are declined in seven [[grammatical case|cases]]: [[nominative]], [[genitive]], [[dative]], [[Accusative case|accusative]], [[instrumental case|instrumental]], [[Locative case|locative]] ([[Inessive case|inessive]]), and [[Vocative case|vocative]]. In older Lithuanian texts, three additional varieties of the locative case are found: [[Illative case|illative]], [[Adessive case|adessive]] and [[Allative case|allative]]. The most common are the [[Illative case|illative]], which is still used, mostly in spoken language, and the [[Allative case|allative]], which survives in the standard language in some idiomatic usages. The adessive is nearly extinct. These additional cases are probably due to the influence of [[Uralic languages]], with which Baltic languages have had a longstanding contact. (Uralic languages possess a great variety of noun cases, a number of which are specialised locative cases.)

Lithuanian verbal morphology shows a number of innovations; namely, the loss of synthetic passive (which is hypothesized based on other archaic Indo-European languages, such as Greek and Latin), [[synthetic perfect]] (formed by means of reduplication) and [[aorist]]; forming [[subjunctive]] and [[imperative mood|imperative]] with the use of suffixes plus flexions as opposed to solely flections in, e.g., [[Ancient Greek]]; loss of the [[optative mood]]; merging and disappearing of the -''t''- and -''nt''- markers for the third-person singular and plural, respectively (this, however, occurs in Latvian and Old Prussian as well and may indicate a collective feature of all Baltic languages).

On the other hand, Lithuanian verbal morphology retains a number of archaic features absent from most modern Indo-European languages (but shared with Latvian). This includes the synthetic form of the future tense with the help of the -''s''- suffix and three principal verbal forms with the present tense stem employing the -''n''- and -''st''- infixes.

There are three [[verb]]al [[grammatical conjugation|conjugation]]s. The verb ''būti'' is the only [[auxiliary verb]] in the language. Together with [[participle]]s, it is used to form dozens of compound forms.

In the '''active voice''', each verb can be inflected for any of the following [[Grammatical mood|moods]]:

# Indicative
# Indirect
# Imperative
# Conditional/subjunctive

In the [[indicative mood]] and indirect moods, all verbs can have eleven [[Grammatical tense|tenses]]:

# simple: [[present tense|present]] (e.g., ''nešu'' 'I carry'), [[past tense|past]] (''nešiau''), [[past iterative tense|past iterative]] (''nešdavau'') and [[future tense|future]] (''nešiu'')
# compound:
## present perfect (''esu nešęs''), past perfect (''buvau nešęs''), past iterative perfect (''būdavau nešęs''), future perfect (''būsiu nešęs'')
## past [[Inchoative aspect|inchoative]] (''buvau benešąs''), past iterative inchoative (''būdavau benešąs''), future inchoative (''būsiu benešąs'')

The [[indirect mood]], used only in written narrative speech, has the same tenses corresponding to the appropriate active participle in nominative case; e.g., the past of the indirect mood would be ''nešęs'', while the past iterative inchoative of the indirect mood would be ''būdavęs benešąs''. Since it is a nominal form, this mood cannot be conjugated but must match the subject's number and gender.

The [[subjunctive mood|subjunctive]] (or [[conditional mood|conditional]]) <!-- see notes in the discussion page of the Lithuanian grammar--> and the [[imperative mood]]s have three tenses. Subjunctive: present (''neščiau''), past (''būčiau nešęs''), inchoative (''būčiau benešąs''); imperative: present (''nešk''), perfect (''būk nešęs'') and inchoative (''būk benešąs'').

The [[infinitive]] has only one form (''nešti''). These forms, except the infinitive and indirect mood, are conjugative, having two singular, two plural persons, and the third person form common both for plural and singular.

In the '''passive voice''', the form number is not as rich as in the active voice. There are two types of passive voice in Lithuanian: present participle (type I) and past participle (type II) (in the examples below types I and II are separated with a slash). They both have the same moods and tenses:

# Indicative mood: [[present tense|present]] (''esu nešamas/neštas''), [[past tense|past]] (''buvau nešamas/neštas''), [[past iterative tense|past iterative]] (''būdavau nešamas/neštas'') and [[future tense|future]] (''būsiu nešamas/neštas'')
# Indirect mood: [[present tense|present]] (''esąs nešamas/neštas''), [[past tense|past]] (''buvęs nešamas/neštas''), [[past iterative tense|past iterative]] (''būdavęs nešamas/neštas'') and [[future tense|future]] (''būsiąs nešamas/neštas'').
# Imperative mood: present (type I only: ''būk nešamas''), past (type II only: ''būk neštas'').
# Subjunctive / conditional mood: present (type I only: ''būčiau nešamas''), past (type II only: ''būčiau neštas'').

Lithuanian has the richest [[participle]] system of all Indo-European languages, having participles derived from all simple tenses with distinct active and passive forms, and two gerund forms.

In practical terms, the rich overall inflectional system makes the word order have a different meaning than in more [[analytic language]]s such as English. The English phrase "'''a''' car is coming" translates as "atvažiuoja automobilis" (the [[Topic and comment|theme]] first), while "'''the''' car is coming" – "automobilis atvažiuoja" (the theme first; word order inversion).

Lithuanian also has a very rich word derivation system and an array of diminutive suffixes.

Today there are two definitive books on Lithuanian grammar: one in English, the ''Introduction to Modern Lithuanian'' (called ''Beginner's Lithuanian'' in its newer editions) by [[Leonardas Dambriūnas]], [[Antanas Klimas]] and [[William R. Schmalstieg]]; and another in Russian, [[Vytautas Ambrazas]]' ''Грамматика литовского языка'' (''Lithuanian Grammar''). Another recent book on Lithuanian grammar is the second edition of ''Review of Modern Lithuanian Grammar'' by Edmund Remys, published by Lithuanian Research and Studies Center, Chicago, 2003.

==Vocabulary==
[[File:Lkz.jpg|thumb|upright=1.5|[[Academic Dictionary of Lithuanian|Great Lithuanian Dictionary]] consists of 20 volumes and contains more than half a million [[headword]]s.]]
[[File:Illustration from Lithuanian-language primer (1824).jpg|thumb|Page from the Lithuanian primer ''Naujas moksłas skaytima diel maźū waykū Źemaycziu yr Lietuwos'' illustrating the letters [[D]], [[E]] and [[G]]]]

===Indo-European vocabulary===
Lithuanian retains [[cognate]]s to many words found in classical languages, such as [[Sanskrit]] and [[Latin language|Latin]]. These words are descended from [[Proto-Indo-European language|Proto-Indo-European]]. A few examples are the following:
* Lith. {{Transliteration|lt|sūnus}} and Skt. {{Transliteration|sa|sūnu}} (son)
* Lith. {{Transliteration|lt|avis}} and Skt. {{Transliteration|sa|avi}} and Lat. ''ovis'' (sheep)
* Lith. {{lang|lt|dūmas}} and Skt. ''d<sup>h</sup>ūma'' and Lat. ''fumus'' (fumes, smoke)
* Lith. {{lang|lt|antras}} and Skt. {{Transliteration|sa|antara}} (second, the other)
* Lith. {{lang|lt|vilkas}} and Skt. ''vṛka'' (wolf)
* Lith. {{lang|lt|ratas}} and Lat. ''rota'' (wheel) and Skt. ''rat<sup>h</sup>a'' (carriage)
* Lith. {{lang|lt|senis}} and Lat. ''senex'' (an old man) and Skt. ''sanas'' (old)
* Lith. {{lang|lt|vyras}} and Lat. ''vir'' (a man) and Skt. ''vīra'' (man)
* Lith. {{lang|lt|angis}} and Lat. ''anguis'' (a snake in Latin, a species of snakes in Lithuanian)
* Lith. {{lang|lt|linas}} and Lat. ''linum'' (flax, compare with English 'linen')
* Lith. {{lang|lt|ariu}} and Lat. ''aro'' (I plow)
* Lith. {{lang|lt|jungiu}} and Lat. ''iungo'', and Skt. ''yuñje'' (mid.), (I join)
* Lith. {{lang|lt|gentys}} and Lat. ''gentes'' and Skt. ''játi'' (tribes)
* Lith. {{lang|lt|mėnesis}} and Lat. ''mensis'' and Skt. ''masa'' (month)
* Lith. {{lang|lt|dantis}} and Lat. ''dens'' and Skt. ''danta'' (tooth)
* Lith. {{lang|lt|naktis}} and Lat. ''noctes'' (plural of ''nox'') and Skt. ''naktam'' (night)
* Lith. {{lang|lt|ugnis}} and Lat. ''ignis'' and Skt. ''agni'' (fire)
* Lith. {{lang|lt|sėdime}} and Lat. ''sedemus'' and Skt. ''sīdama'' (we sit)

This even extends to grammar, where for example Latin noun declensions ending in ''-um'' often correspond to Lithuanian ''-ų'', with the [[Latin declension#Fourth declension (u)|Latin]] and [[Lithuanian declension#Table of noun declension endings|Lithuanian fourth declensions]] being particularly close. Many of the words from this list are similar to other Indo-European languages, including English and Russian. The contribution of Lithuanian was influential in the reconstruction of [[Proto-Indo-European language|Proto-Indo-European]].

Lexical and grammatical similarities between Baltic and [[Slavic languages]] suggest an affinity between these two language groups. On the other hand, there exist a number of Baltic (particularly Lithuanian) words without counterparts in Slavic languages, but which are similar to words in Sanskrit or Latin.<!-- Not from the list above. Cf. Russian сын, овца, дым, волк, etc. --> The history of the relationship between Baltic and Slavic languages, and our understanding of the affinity between the two groups, remain in dispute (see: [[Balto-Slavic languages]]).

===Loanwords===
In a 1934 book entitled ''Die Germanismen des Litauischen. Teil I: Die deutschen Lehnwörter im Litauischen'', K. Alminauskis found 2,770 loanwords, of which about 130 were of uncertain origin. The majority of the loanwords were found to have been derived from [[Polish language|Polish]], [[Belarusian language|Belarusian]], and [[German language|German]], with some evidence that these languages all acquired the words from contacts and trade with [[Prussia]] during the era of the [[Grand Duchy of Lithuania]].<ref>{{Cite journal |last=Cepiene |first=N. |date=2006 |title=Ways of Germanisms into Lithuanian |url=http://cejsh.icm.edu.pl/cejsh/cgi-bin/getdoc.cgi?07PLAAAA02144515c |url-status=dead |journal=Acta Baltico-Slavica |type=Abstract |volume=30 |pages=241–250 |archive-url=https://web.archive.org/web/20120206043012/http://cejsh.icm.edu.pl/cejsh/cgi-bin/getdoc.cgi?07PLAAAA02144515 |archive-date=6 February 2012}}</ref> Loanwords comprised about 20% of the vocabulary used in the first book printed in Lithuanian in 1547, [[Martynas Mažvydas]]'s ''[[Catechism]]''.<ref>{{Cite web |last=Zinkevičius |first=Zigmas |author-link=Zigmas Zinkevičius |date=1996 |title=Martynas Mažvydas' Language |url=http://pirmojiknyga.mch.mii.lt/Leidiniai/History.en.htm |archive-url=https://web.archive.org/web/20160304023445/http://pirmojiknyga.mch.mii.lt/Leidiniai/History.en.htm |archive-date=4 March 2016 |access-date=26 October 2007 |via=pirmojiknyga.mch.mii.lt}}</ref> But as a result of language preservation and purging policies, Slavic loanwords currently constitute only 1.5% of the Standard Lithuanian lexicon, while German loanwords constitute only 0.5% of it.<ref>{{Cite web |title=Skoliniai |url=http://www.patariu.lt/studijos/2010/11/skoliniai/ |url-status=dead |archive-url=https://archive.today/20130219022046/http://www.patariu.lt/studijos/2010/11/skoliniai/ |archive-date=19 February 2013 |website=Studijos |language=lt |access-date=21 November 2012}}</ref> The majority of loanwords in the 20th century arrived from [[Russian language|Russian]].<ref>{{Cite journal |last=Sakalauskienė |first=V. |date=2006 |title=Slavic loanwords in the northern sub-dialect of the southern part of west high Lithuanian |url=http://cejsh.icm.edu.pl/cejsh/cgi-bin/getdoc.cgi?07PLAAAA02154540 |journal=Acta Baltico-Slavica |type=Abstract |volume=30 |pages=221–231 |archive-url=https://web.archive.org/web/20120206043018/http://cejsh.icm.edu.pl/cejsh/cgi-bin/getdoc.cgi?07PLAAAA02154540 |archive-date=6 February 2012 |access-date=26 October 2007}}</ref>

Towards the end of the 20th century, a number of words and expressions related to new technologies and telecommunications were borrowed from [[English language|English]]. The Lithuanian government has an established language policy that encourages the development of equivalent vocabulary to replace loanwords.<ref>{{Cite web |last=Seimas of Lithuania |date=2003 |title=State Language Policy Guidelines 2003–2008 |url=http://www.vlkk.lt/files/language_policy_guidelines.doc |archive-url=https://web.archive.org/web/20061001220256/http://www.vlkk.lt/files/language_policy_guidelines.doc |archive-date=1 October 2006 |access-date=26 October 2007 |url-status=live}}</ref> However, despite the government's best efforts to avoid the use of loanwords in Lithuanian, many English words have become accepted and are now included in Lithuanian language dictionaries.<ref>{{Cite web |title=English to Lithuanian to English Dictionary |url=http://www.dicts.info/2/english-lithuanian.php?word=student |url-status=dead |archive-url=https://web.archive.org/web/20110628231229/http://www.dicts.info/2/english-lithuanian.php?word=student |archive-date=2011-06-28 |website=Dicts.info}}</ref><ref>{{Cite web |title=Lingvozone English to Lithuanian Online Dictionary |url=http://www.lingvozone.com/ |archive-url=https://web.archive.org/web/20081014110255/http://www.lingvozone.com/ |archive-date=14 October 2008 |website=Lingvozone.com}}</ref> In particular, words having to do with new technologies have permeated the Lithuanian vernacular, including such words as:
* Monitorius (vaizduoklis) ([[computer monitor]])
* Faksas ([[fax]])
* Kompiuteris ([[computer]])
* Failas (byla, rinkmena) ([[electronic file]])

Other common foreign words have also been adopted by Lithuanian. Some of these include:
* Taksi ([[taxicab|taxi]])
* Pica ([[pizza]])
* Alkoholis ([[Alcohol (chemistry)|alcohol]])
* Bankas ([[bank]])
* Pasas ([[passport]], pass)
* Parkas ([[park]])

These words have been modified to suit the grammatical and phonetic requirements of Lithuanian, mostly by adding -as ending, but their foreign roots are obvious.

The language of the earliest Lithuanian writings, in the 16th and 17th centuries, is known as '''Old Lithuanian''' and differs in some significant respects from the Lithuanian of today.

Besides the specific differences given below, nouns, verbs, and adjectives still had separate endings for the [[dual (grammatical number)|dual number]]. The dual persists today in some dialects. Example:
{| class="wikitable"
|-
! Case !! "two good friends"
|-
| Nom-Acc || dù gerù draugù
|-
| Dat || dvı̇́em gerı̇́em draugám
|-
| Inst || dviẽm geriẽm draugam̃
|}

===Pronunciation===
The vowels written ''ą, ę, į, ų'' were still pronounced as long [[nasal vowel]]s,{{sfnp|Ambrazas et al.|1997|p=13}} not as long oral vowels as in today's Lithuanian.

The original Baltic long ''ā'' was still retained as such, e.g. ''bralis'' 'brother' (modern ''brólis'').

===Nouns===
Compared to modern Lithuanian, there were three additional cases. The original [[locative case]] had been replaced by four so-called ''postpositive'' cases, the [[inessive case]], [[illative case]], [[adessive case]] and [[allative case]], which correspond to the prepositions "in", "into", "at" and "towards", respectively. They were formed by affixing a [[postposition]] to one of the previous cases:

* The inessive added ''*-en'' > ''-e'' to the original locative in singular and to the accusative in plural.
* The illative added ''*-nā'' > {{lang|lt|-n(a)}} to the accusative.
* The adessive added ''*-pie'' > ''-p(i)'' to the original locative in singular and to the inessive in plural.
* The allative added ''*-pie'' > ''-p(i)'' to the genitive.

The inessive has become the modern locative case, while the other three have disappeared. Note, however, that the illative case is still used occasionally in the colloquial language (mostly in the singular): ''Lietuvon'' 'to Lithuania', ''miestan'' 'to the city'. This form is relatively productive: for instance, it is not uncommon to hear "skrendame Niujork'''an''' (we are flying to New York)". There are some words still used in adessive case: esu "namie" (could be equally substituted with "namuose") I'm 'at home'.

The uncontracted dative plural ''-mus'' was still common.

===Adjectives===
Adjectives could belong to all four accent classes in Old Lithuanian (now they can only belong to classes 3 and 4).

Additional remnants of i-stem adjectives still existed, e.g.:
* loc. sg. {{lang|olt|didimè pulkè}} 'in the big crowd' (now {{lang|lt|didžiame}})
* loc. sg. ''gerèsnime'' 'better' (now ''geresniamè'')
* loc. sg. ''mažiáusime'' 'smallest' (now ''mažiáusiame'')

Additional remnants of u-stem adjectives still existed, e.g. ''rūgštùs'' 'sour':
{| class="wikitable"
|-
! Case !! Newer !! Older
|-
| Inst sg || rūgščiù || rūgštumı̇̀
|-
| Loc sg || rūgščiamè || rūgštumè
|-
| Gen pl || rūgščių̃ || rūgštų̃
|-
| Acc pl || rū́gščius || rū́gštus
|-
| Inst pl || rūgščiaı̇̃s || rūgštumı̇̀s
|}

No u-stem remnants existed in the dative singular and locative plural.

Definite adjectives, originally involving a pronoun suffixed to an adjective, had not merged into a single word in Old Lithuanian. Examples:
* ''pa-jo-prasto'' 'ordinary' (now ''pàprastojo'')
* ''nu-jie-vargę'' 'tired' (now ''nuvar̃gusieji'')

===Verbs===
The [[Proto-Indo-European language|Proto-Indo-European]] class of [[athematic verb]]s still existed in Old Lithuanian:
{| class="wikitable"
|-
! &nbsp; !! 'be' !! 'remain' !! 'give' !! 'save'
|-
| 1st sg || esmı̇̀ || liekmı̇̀ || dúomi || gélbmi
|-
| 2nd sg || esı̇̀ || lieksı̇̀ || dúosi || gélbsi
|-
| 3rd sg || ẽst(i) || liẽkt(i) || dúost(i) || gélbt(i)
|-
| 1st dual || esvà || liekvà || dúova || gélbva
|-
| 2nd dual || està || liektà || dúosta || gélbta
|-
| 1st pl || esmè || liekmè || dúome || gélbme
|-
| 2nd pl || estè || liektè || dúoste || gélbte
|-
| 3rd pl || ẽsti || liẽkt(i) || dúost(i) || gélbt(i)
|}

The [[optative mood]] (i.e. the third-person imperative) still had its own endings, ''-ai'' for third-conjugation verbs and ''-ie'' for other verbs, instead of using regular third-person present endings.

===Syntax===
Word order was freer in Old Lithuanian. For example, a noun in the [[genitive case]] could either precede or follow the noun it modifies.
