Vokaaliyhdistelmiä
Vokaaliyhdistelmiä, or vowel combinations, refers to sequences of two or more vowel sounds or letters appearing consecutively within a word. These combinations can occur within a single morpheme or across morpheme boundaries. In Finnish, common vowel combinations include diphthongs, which are single-syllable vowel sounds where one vowel glides into another. Examples of Finnish diphthongs include "ai" as in "aika," "oi" as in "poika," "ei" as in "leikki," "au" as in "kaunis," "eu" as in "neumonia," "iu" as in "tiuha," "ou" as in "joulu," "uy" as in "tyylikäs," "yi" as in "kyinen," "äi" as in "sääi," "öi" as in "köyhä," "äy" as in "käyttää," and "öy" as in "höyry."
Beyond diphthongs, other vowel combinations can appear, such as sequences of identical vowels, like "aa" in "saari,"
