Kärkipisteen

Kärkipisteen is a Finnish linguistic form—the genitive singular of the compound noun kärkipiste. The stem kärkipiste combines kärki, meaning apex or tip, with piste, meaning point. The result refers to an apex point or tip point, and its genitive form signals possession or a relation to that apex point.

In Finnish, the genitive singular is formed by adding the suffix -en to the noun, and this suffix attaches to the entire compound könten, not just its second element. Thus, kärkipiste becomes kärkipisteen in the genitive. This construction is common in technical and descriptive writing where the attribute belongs to or is attributed to the apex point of a figure or object.

Usage and examples: Kärkipisteen is used to indicate the location, direction, or properties of the apex point in diagrams, geometry, or drafting. Examples include phrases such as kärkipisteen koordinaatit (the coordinates of the apex point) or kärkipisteen suunta (the direction of the apex point). The form can also appear in more abstract or metaphorical contexts where an apexes or peak point is being described.

Relation to related terms: Kärkipisteen relates to kärkipiste (the apex point) and to other Finnish geometric vocabulary such as piste (point) and kärki (apex, tip). It also illustrates how Finnish uses genitive forms with compound nouns to express ownership, association, or attribution in technical language.
