yksikköihinsä

The Finnish word "yksikköihinsä" is a grammatical form derived from the noun "yksikkö," which translates to "unit" or "individual" in English. Specifically, "yksikköihinsä" is the third-person plural possessive in the allative case. This means it refers to something belonging to multiple "units" or "individuals," and indicates movement or direction towards them.

To break it down, "yksikkö" is the base word. The plural form is "yksiköt." The possessive suffix for the third-person plural (referring to them or their own) is "-nsä." Finally, the allative case ending, indicating movement towards, is "-ihin." Therefore, "yksikköihinsä" literally translates to "into their own units" or "towards their own individuals."

This form is used in sentences where a subject is acting upon or moving towards something that belongs to multiple entities. For example, one might say "The commander led his soldiers back to their own units" (Komentaja johti sotilaansa takaisin omiin yksikköihinsä). The context dictates whether "yksikkö" refers to military units, organizational units, or even individual people in a group. The possessive "-nsä" emphasizes that the units belong to the subject of the sentence.
