===Vowel clusters and diphthongs===
Word-final vowel clusters ending in {{IPA|/ɑ/}} or {{IPA|/æ/}} have much variation in dialects of Finnish. Especially in Helsinki they assimilate, where only the resulting [[chroneme]] marks the partitive in many words.
: {{lang|fi|puhun suomea}} &mdash; {{lang|fi|puhun suomee}} "I speak Finnish"
: {{lang|fi|pitkiä}} &mdash; {{lang|fi|pitkii}} "(some) long (things)"; partitive plural of {{lang|fi|pitkä}}, long
An {{IPA|/eɑ/}} or {{IPA|/eæ/}} cluster also appears in many adjectives:
: {{lang|fi|pimeä}} — {{lang|fi|pimee}} "dark"
In other areas of Finland, these clusters may have a different fate. Another common dialectal variant is the raising of {{IPA|/e/}} to {{IPA|/i/}} in the adjectives: {{lang|fi|pimiä}}. (Partitives are unaffected by this.) Some rarer versions of this suffix include {{lang|fi|-jä / -ja}}, {{lang|fi|-ie}}, and even {{lang|fi|-ii}}.

Similar to the diphthongization of older {{IPA|*/eː oː øː/}} to {{IPA|/{{Not a typo|ie̯}} uo̯ yø̯/}} (unchanged in standard [[Estonian language|Estonian]]), many eastern dialects of Finnish diphthongize also the long vowels {{IPA|/ɑː æː/}} to {{IPA|/oɑ̯ eæ̯/}}. In [[Savonian dialects]], these have shifted further on to {{IPA|/uɑ̯ iæ̯/}}.

{{IPA|/{{Not a typo|ie̯}} uo̯ yø̯/}} can become {{IPA|/iː uː yː/}} when in contact with another vowel. In many cases this results from colloquial deletion of {{IPA|/d/}}. For example:
* {{lang|fi|tiiän}} for standard {{lang|fi|tiedän}} "I know"
* {{lang|fi|viiä}} for standard {{lang|fi|viedä}} "to take away"
* {{lang|fi|lyyä}} for standard {{lang|fi|lyödä}} "to hit"
* {{lang|fi|tuua}} for standard {{lang|fi|tuoda}} "to bring"
