taivutuspääteyhteydessä

Taivutuspääteyhteys is a Finnish grammatical concept that refers to the way a noun, pronoun, or adjective can take a case ending that also signifies a possessive relationship. This means a single ending can indicate both the grammatical case of the word and who or what it belongs to. It is not a separate case itself but rather a functional description of how existing cases can be used.

For example, in Finnish, the genitive case ending can indicate possession. The word "talo" (house) in the genitive case is "talon". When this is used in a possessive context, it translates to "the house's" or "of the house". If this were used in conjunction with a pronoun, like "minun taloni" (my house), the possessive is explicitly marked by the pronoun, and the noun takes a different ending, the possessive suffix. However, in simpler possessive constructions, like "talon katto" (the house's roof), the genitive ending "-n" on "talo" serves the taivutuspääteyhteys.

This phenomenon allows for a more compact and efficient expression of possession within the Finnish language, relying on the inflectional system to convey multiple pieces of grammatical information simultaneously. It is a characteristic feature of Finnish morphology.
