kansallisiin

Kansallisiin is the illative plural form of the Finnish adjective kansallinen, meaning national. It is used when the attribute modifies a plural noun in the illative case, typically in contexts describing movement into or grouping by national categories.

Formation and grammar: Kansallisiin is derived from kansallinen with the illative plural ending -isiin, which accompanies adjectives ending in -inen. The corresponding base forms include kansallinen (singular nominative), kansallisen (genitive singular), kansallisia (partitive/plural), and kansalliset (nominative plural). The illative plural kansallisiin signals “into national groups” or “to the national groups,” depending on the sentence and accompanying nouns.

Usage: Kansallisiin mainly appears in written Finnish, especially in sociological, ethnographic, or statistical contexts where things are categorized by nation or national-group membership. It is not a standalone noun; it functions as an adjective modifying a plural noun in the illative case. Example: Tutkimuksessa osallistujat jaettiin kansallisiin ryhmiin, meaning the participants were divided into national groups.

Notes: The concept is tied to the broader Finnish adjective inflection system, particularly the -inen adjectives and their various case endings. Related forms include kansallinen in its other cases and numbers. In English rendering, kansallisiin translates roughly to “to/into national [groups]” depending on context.
