Kotikaupunkiinsa

Kotikaupunkiinsa is a Finnish grammatical form meaning “to his/her hometown.” It is not a standalone noun; it is the word kotikaupunki (hometown) combined with the illative case marker that signals motion into a place, plus the third-person possessive suffix. The resulting surface form indicates both the destination and the person to whom the destination belongs.

Morphology and construction: The illative suffix marks direction into a place (into the hometown), and the possessive suffix -sa/-sä attaches to indicate “his,” “her,” or “its.” The combined form kotikaupunkiinsa thus conveys “to his/her hometown.” This kind of fused form is common in Finnish, where case endings and possessive endings can stack on a noun.

Usage: Kotikaupunkiinsa appears in sentences describing moving toward or returning to one’s hometown, and it can also appear with verbs of sending or directing something to that destination. Examples include: Hän palasi kotikaupunkiinsa (He returned to his hometown). Hän muutti kotikaupunkiinsa viime vuonna (He moved to his hometown last year). The construction emphasizes both the destination and the possessor of the hometown.

Notes: Kotikaupunkiinsa is a normal, widely used inflected form rather than a proper noun. In everyday speech, it is common to use kotikaupunkiin without the possessive suffix when the possessor is obvious or not specified.
