Editing Attic Greek (section)

==Grammar==
Attic Greek grammar follows [[Ancient Greek grammar]] to a large extent. References to Attic Grammar are usually in reference to peculiarities and exceptions from Ancient Greek Grammar. This section mentions only some of said peculiarities.

===Number===
{{main|Attic numerals}}
In addition to singular and plural numbers, Attic Greek had the [[dual (grammatical number)|dual number]]. This was used to count exactly two of something and was present as an inflection in nouns, adjectives, pronouns, and verbs (i.e., any categories inflected for number). Attic Greek was the last dialect to retain it from older forms of Greek, and the dual number had died out by the end of the 5th century BC. In addition to this, in Attic Greek, any plural neuter subjects will only ever take singular conjugation verbs.

===Declension===
{{main|Attic declension}}
With regard to [[declension]], the stem is the part of the declined word to which case endings are suffixed. In the alpha or first declension feminines, the stem ends in long ''a'', which is parallel to the Latin first declension. In Attic–Ionic the stem vowel has changed to ''ē'' in the singular, except (in Attic only) after ''e'', ''i'' or ''r''. For example, the respective nominative, genitive, dative, and accusative singular forms are γνώμη (''gnome''), γνώμης (''gnomes''), γνώμῃ (''gnome(i)''), γνώμην (''gnomen''), "opinion"; but θεᾱ́ (''thea''), θεᾶς (''theas''), θεᾷ (''thea(i)''), θεᾱ́ν (''thean''), "goddess".

The plural is the same in both cases, ''gnomai'' and ''theai'', but other sound changes were more important in its formation. For example, original ''-as'' in the nominative plural was replaced by the diphthong ''-ai'', which did not change from ''a'' to ''e''. In the few ''a''-stem masculines, the genitive singular follows the second declension: ''stratiotēs'', ''stratiotou'', ''stratiotēi'', etc.

In the omicron or second declension, mainly masculines (but with some feminines), the stem ends in ''o'' or ''e'', which is composed in turn of a root plus the [[thematic vowel]], an ''o'' or ''e'' in [[Indo-European ablaut]] series parallel to similar formations of the verb. It is the equivalent of the Latin second declension. The alternation of Greek ''-os'' and Latin ''-us'' in the nominative singular is familiar to readers of Greek and Latin.

In Attic Greek, an original [[genitive]] singular ending ''*-osyo'' after losing the ''s'' (like in the other dialects) lengthens the stem ''o'' to the spurious diphthong ''-ou'' (see above under Phonology, Vowels): logos "the word" ''logou'' from *''logosyo'' "of the word". The dative plural of Attic–Ionic had ''-oisi'', which appears in early Attic but later simplifies to ''-ois'': ''anthropois'' "to or for the men".
