ympäröimän
ympäröimän is the genitive singular form of the Finnish verb ympäröidä. The verb ympäröidä means to surround, to encircle, or to encompass. Therefore, ympäröimän refers to the act of surrounding, or to something that is in the state of being surrounded, in a possessive or genitive context. For example, in a sentence like "hän oli talon ympäröimän," it would translate to "he was in the surrounding of the house," or more naturally, "he was surrounded by the house." The genitive case in Finnish is often used to express possession, belonging, or a relationship to something. Thus, ympäröimän specifically indicates the genitive case of the present active participle of the verb ympäröidä. This participle form describes an ongoing action or a state.
