päätehtäviensä

The Finnish word "päätehtäviensä" translates to "their main tasks" or "their primary responsibilities" in English. It is the genitive plural form of the noun "päätehtävä," which itself is a compound word derived from "pää" (head, main, chief) and "tehtävä" (task, duty, assignment).

"Päätehtäviensä" is used when referring to the core duties or responsibilities belonging to multiple entities or individuals. For example, in a sentence like "Opettajien päätehtäviensä toteutuminen varmistetaan säännöllisillä arvioinneilla" (The realization of the teachers' main tasks is ensured by regular evaluations), "päätehtäviensä" indicates that the sentence is discussing the primary responsibilities of more than one teacher.

The grammatical structure of "päätehtäviensä" reflects Finnish's agglutinative nature. The base word is "tehtävä," to which the plural marker "-i-" is added, followed by the genitive case ending "-n," and finally the possessive suffix "-nsä," which indicates "their" or "his/her/its" when referring to a third person. Therefore, "päätehtäviensä" is a precise way to express the concept of multiple main tasks belonging to a group. This term is common in professional contexts, official documents, and discussions about roles and obligations.
