ryhmääänsä

Ryhmä is a Finnish noun meaning a collection of people or things. Ryhmänsä is the possessive form used to indicate that the group belongs to someone or something, and it translates roughly as "his/her/its group" or, depending on the context, "their group." The form is built from the genitive of ryhmä, ryhmän, plus the third-person possessive suffix sä, yielding ryhmänsä. In practice, the exact possessor (singular or plural) is inferred from the surrounding context or explicit pronouns.

Usage of ryhmänsä is common in descriptions of organizations, teams, committees, classrooms, or other collections that are owned or led by a person or entity. For example: Hän osallistuu kilpailuun ryhmänsä kanssa, meaning “He participates in the competition with his/her group,” or Heidän ryhmänsä on kasvanut, meaning “Their group has grown.” The phrase can appear with subsequent noun phrases, as in ryhmänsä jäsenet (members of his/her/its group) or ryhmänsä ohjelma (the group’s program).

Grammatical notes: The suffix -sä (or -nsä, depending on phonological harmony) marks third-person possession and attaches to the genitive stem ryhmän. Context determines whether the possessor is singular or plural; Finnish typically relies on pronouns or article-like context to indicate exact ownership when necessary.
