mainfinitiivimuoto

Mainfinitiivimuoto, often described in Finnish grammars as the ma-infinitive, is a non-finite verb form formed with the suffix -ma or -mä attached to the verb stem. It functions as a noun-like element that expresses the act or process of the verb. In many descriptions it is presented as a separate non-finite form alongside the standard infinitive and participles, and it is sometimes treated as a gerund-like form in usage.

The ma-infinitive is used in several ways. It can serve as a subject or object within a clause, much like a noun: for example, sentences may center on the act of doing something. It is also used to express means or manner, often in constructions that convey “by doing” or “through doing.” Because it denotes an action as a concept rather than a specific event tied to a subject, its appearance is more common in formal or written Finnish than in everyday speech.

Usage and variation: the term mainfinitiivimuoto appears in some grammar sources, while others describe the same or similar forms under different terms such as the ma-infinitive or related gerund-like constructions. The exact terminology and analysis can vary between grammars, but the functional idea remains: the ma-infinitive provides a non-finite, noun-like way to reference actions or processes.
