Peruspartisiipin

Peruspartisiipin is a term used in Finnish linguistics to refer to the base form or stem of a verb when it is treated as a participle. It is a theoretical construct rather than a single, directly used inflected form. The peruspartisiipin serves as the starting point from which the various participial forms in Finnish are derived, such as the present active participle, the past active participle, and the passive participle, by applying different suffixes and inflectional endings.

In grammar descriptions, the peruspartisiipin is described as the non-finite participial stem that underlies several participial constructions. The exact shape of this stem depends on the verb class and phonological processes, and different verbs may show different derivational paths. The concept helps explain how a single verb can yield multiple participial forms without prescribing a unique standalone form that is always used in running text.

Examples are used mainly to illustrate the relationship rather than to prescribe a single canonical form. For instance, with a verb like kirjoittaa (to write), various participial forms such as kirjoittava or kirjoitettu are said to be derived from its peruspartisiipin, though the precise base may differ according to grammar rules and the verb’s productivity. The peruspartisiipin is thus a tool for understanding participle formation rather than a directly usable form in ordinary sentence construction.

In summary, peruspartisiipin is a technical Finnish grammar notion describing the participle’s base stem from which related participial forms are generated.
