henkilöllä

Henkilöllä is a Finnish grammatical case, specifically the genitive case. It is used to indicate possession or a relationship between two entities. In Finnish, the genitive case is often translated into English using "of" or by using the possessive form (e.g., "John's"). However, it's important to note that the Finnish genitive has broader applications than just simple possession.

The primary function of the genitive is to show ownership. For example, "talon katto" translates to "the house's roof" or "the roof of the house." Here, "talon" is the genitive form of "talo" (house). The genitive case is also used to indicate the object of certain verbs and prepositions. For instance, some verbs require their object to be in the genitive case. Similarly, certain postpositions (words that follow the noun they modify) govern the genitive.

Another common use of the genitive is in partitive constructions, often in combination with adjectives or numerals. It can also indicate the origin or source of something. The formation of the genitive case in Finnish depends on the specific noun's declension class, with different suffixes being added to the stem. Understanding the genitive is crucial for comprehending Finnish grammar and constructing grammatically correct sentences.
