päälauseisiin

Päälauseisiin is the illative plural form of päälause, a Finnish term meaning main clause. In Finnish grammar, päälause refers to independent or main clauses, as opposed to alilause, which are subordinate clauses. The illative form signals movement or relation “into” or “toward” something, and in this case it marks the plural destination or field of reference as part of a grammatical description.

Morphology and formation: The base form päälauseet is the nominative plural of päälause. To form the illative plural, the suffix -iin is added, producing päälauseisiin. This is a routine pattern for many Finnish nouns in the illative plural, and it is mainly encountered in linguistic discussions, grammars, or formal analyses rather than everyday speech.

Usage and context: Päälauseisiin is typically used in academic or theoretical contexts to discuss structures, relations, or phenomena connected to main clauses. It appears in phrases such as päälauseisiin liittyviä lauserakenteita, meaning “the clause structures related to the main clauses.” The illative plural emphasizes a referential domain (the main clauses) rather than a simple nominative or genitive reference.

Examples: In practice, you might see sentences like “Tässä luvussa tarkastellaan päälauseisiin liittyviä lauserakenteita.” or “Päälauseisiin kuuluvia alilauseita analysoidaan.” These illustrate how the illative plural marks a topic or domain within linguistic descriptions.
