Verbimuoto

Verbimuoto is a term used in Finnish grammar to describe any inflected form of a verb. Each verbimuoto carries grammatical information that can indicate tense, mood, voice, person, number, and often modality or negation. The base or dictionary form of a verb is not itself a verbimuoto; it is the lemma from which forms are derived.

In grammar, verbimuodo are commonly divided into finite and non-finite forms. Finite forms are those that can function as the predicate of a clause and show agreement with the subject, such as person and number in present or past meaning. Non-finite forms do not carry subject agreement and are used in other syntactic roles, for example as infinitives, participles, or gerund-like forms, to form compound tenses or to modify nouns.

Across languages, the specific set and labeling of verbimuodo vary. Some languages provide a rich system of verb forms for different tenses, moods, and voices, while others rely more on auxiliary words or periphrastic constructions. The concept remains the same: a verbimuoto is any morphologically distinct version of a verb used in actual speech or writing.

Illustrative examples help clarify the idea. In English, verb forms include base forms like to eat (infinitive), eats (third-person singular present), ate (simple past), and eating (present participle/gerund). In Finnish, examples include syödä (the infinitive), syön (I eat, a finite present form), söin (I ate), and syönyt (having eaten). These forms show how a single verb can appear in multiple morphologically distinct shapes to convey different meanings.
