tyypillisiin

Tyypillisiin is a Finnish adjective form, the illative plural of the word tyypillinen, meaning typical. In Finnish, adjectives decline to agree with the noun they modify, including number and case. The illative case expresses direction “into” or “toward,” and the plural form is used when the noun being described is plural. Therefore tyypillisiin is used with plural nouns in the illative case, such as tyypillisiin piirteisiin (into typical features).

Usage and examples

In descriptive and analytical writing, tyypillisiin is common when listing characteristics or features. A typical construction is Tyypillisiin piirteisiin kuuluvat …, which translates roughly as “Typical features include …” The phrase is often followed by a list of characteristics or observations. Because it is a grammatical inflection, tyypillisiin cannot stand alone as a concept; it accompanies a plural noun that is in the illative case.

Relation to other forms

Tyypillisiin contrasts with other inflected forms of tyypillinen, such as tyypillinen (nominative singular, “typical”) or tyypilliset (nominative plural, “typical”). Finnish adjectives align with the nouns they modify, so different cases and numbers yield different endings, of which -isiin is the illative plural.

Notes

The term is primarily a grammatical form rather than a separate lexical entry. It appears across disciplines that describe characteristics, features, or patterns, including linguistics, research reports, and journalism, wherever Finnish text uses an illative plural construction to discuss typical attributes.
