järjestelmiensä

Järjestelmiensä is a Finnish possessive-genitive form used to indicate something belonging to someone’s systems. In English it translates roughly as “their systems” or “of their systems.” It is a plural possessive construction tied to a third-person possessor.

Morphology: The base word is järjestelmä (system). Its plural is järjestelmät (systems). To express possession by a third person, Finnish uses the possessive suffix -nsa or -nsä attached to the noun; in the plural/genitive form this yields järjestelmiensä. The exact spelling follows vowel harmony rules, hence the suffix appears as -sä here. The form functions within a noun phrase in the genitive case, indicating ownership or association with the noun phrase’s subject.

Usage: It is found in sentences that discuss the characteristics or security of systems belonging to others, often in corporate or technical contexts. Example: Monet IT-yritykset ovat päivittäneet järjestelmiensä turvallisuuden. Translation: Many IT companies have updated the security of their systems.

Notes: Järjestelmiensä exemplifies how Finnish combines a base word (järjestelmä) with the plural form and a third-person possessive suffix to express possession across a multi-item noun phrase. It relates to broader Finnish grammar topics such as genitive constructions and possessive suffixes.
