Koulujen

Koulujen is the genitive plural form of the Finnish noun koulu, meaning the schools or “of the schools.” It is used to indicate possession or relation to more than one school and does not function as a separate standalone word.

In Finnish grammar, the genitive plural is formed by adding -jen to the singular stem, so koulu becomes koulun in the genitive singular and koulujen in the genitive plural. The noun that is possessed typically follows the genitive plural, as in phrases such as koulujen rakennukset (the schools’ buildings), koulujen budjetti (the schools’ budget), or koulujen opettajat (the schools’ teachers). For a single school, the corresponding form is koulun (the school’s).

Usage notes include that koulujen commonly appears in formal and informal writing alike, particularly in contexts related to education, administration, and reporting. Because it denotes possession by multiple schools, it is often found in discussions of school districts, collaborations among institutions, or collective facilities and resources. The capitalization of koulujen follows standard Finnish spelling rules: it is lowercase unless it begins a sentence or appears in a title.
