Selkeimmän
Selkeimmän is the genitive singular form of the Finnish adjective "selkeä," which translates to "clear" or "distinct." In Finnish grammar, the genitive case is used to indicate possession, origin, or a relationship between nouns, similar to how the possessive 's or the word "of" is used in English. Therefore, "selkeimmän" specifically refers to "of the clearest" or "the clearest's."
This form is most commonly encountered when describing something that belongs to, is related to, or is
