ttääverb

ttääverb is a Finnish verb conjugation pattern that occurs with certain verbs ending in -ttää. This pattern involves a change in the vowel sound of the suffix, typically from /ä/ to /e/, when the verb is conjugated in certain grammatical contexts. It is not a separate verb itself but rather a phonetic and orthographic phenomenon observed in the inflection of specific verbs.

The most common examples of verbs exhibiting this ttääverb pattern are those with an infinitive form ending in -ttää, such as *antaa* (to give), *täällä* (here, often used adjectivally or adverbially but can have verb-like functions in certain constructions), and *säätää* (to adjust). In standard Finnish, the infinitive suffix is -ä. However, when these verbs are conjugated in certain tenses or moods, or when followed by specific clitics, the vowel in the suffix might shift.

The exact conditions for the ttääverb phenomenon are tied to Finnish phonology and morphology. It is a predictable variation rather than an irregular one. Understanding this pattern is crucial for accurate Finnish grammar, particularly when reading or writing texts where these specific verbs appear in various forms. Learners of Finnish often encounter this as part of mastering verb conjugations and the interplay of sound changes in the language.
