Koulunsa

Koulunsa is a Finnish noun phrase meaning his, her, or its school. It is formed from the noun koulu (school) with the third-person possessive suffix -nsA, producing a word that denotes ownership by a third person. The spelling typically appears as koulunsa in standard Finnish.

In grammatical terms, koulunsa is an instance of the Finnish possessive construction. It functions as a noun phrase indicating ownership, and the owner is understood from context or can be specified with a separate possessive noun (for example, hänen koulunsa, meaning his or her school). The phrase can serve as the subject or object in a sentence without additional case endings when referring to ownership rather than movement or direction. When indicating movement toward the school, the illative case is used instead, as in kouluunsa meaning into his or her school.

Usage of koulunsa is common in everyday Finnish and in written language, including storytelling, reporting, and dialogue. It is one of several third-person possessive forms, alongside other possessors like hänen koulunsa (her/his/its school) and contrasts with first- and second-person forms such as minun kouluni (my school) or sinun koulusi (your school), as well as with possessives for plural owners like koulunne (your [plural] school).

Examples:

- Koulunsa on vanha. (His/her school is old.)

- Hänen koulunsa on kaupungin vanhin. (Her/his school is the oldest in the city.)

- Koulunsa paloi viime vuonna. (His/her/its school burned last year.)
