Peräiseen

Peräiseen is a rarely attested term in Finnish linguistics. It is not a standard vocabulary item but appears mainly in discussions of Finnish morphology as a potential illative form associated with the adjective derived from the noun perä, meaning rear or hind part. In this usage, peräiseen would express motion toward or into the rear part of something. The form is seldom encountered in contemporary Finnish outside of linguistic demonstrations, archaic prose, or dialectal contexts.

Etymology: built from perä ('rear') + -inen (adjective suffix) to form peräinen, with the illative suffix -iseen producing peräiseen. This derivation aligns with Finnish patterns where -iseen marks directional illative for certain -inen adjectives.

Usage: Because it is atypical, peräiseen is mostly cited in grammars or academic discussions as an example rather than a productive form. When present, it occurs in formal, literary, or dialectal registers to evoke archaism or precise spatial relations, rather than in everyday speech.

Related terms: See also Finnish illative case, -inen adjectives, perä (rear). These provide context for understanding how directional and descriptive forms are constructed in Finnish and how such forms may appear in linguistic analyses or older texts.
