Pisteen

Pisteen is the genitive singular form of the Finnish noun piste, which means point, dot, or mark. As a grammatical form, pisteen is used to indicate possession or association with a point or mark, such as the characteristics of a point or the use of a mark in a system of notation.

In mathematics and geometry, pisteen koordinaatit describe the coordinates of a single point; for example, Pisteen koordinaatit ovat (2, 3). The genitive form enables phrases that specify relationships or attributes related to that point, such as distance to another point or the color of a plotted point.

In typography and writing, piste can denote the punctuation mark period. Pisteen käyttö lauseen lopussa is a common expression describing the use of a period at the end of a sentence. The genitive pisteen here marks the object of discussion—the use of the punctuation mark.

Pisteen is also employed in broader technical and descriptive contexts to form compound phrases that refer to a particular dot or position. Examples include pisteen etäisyys (the distance to a point) or pisteen väri (the color of the dot). Because Finnish relies on inflection rather than prepositions to show relationships, pisteen frequently appears in constructions that would use possessive or genitive forms in English.

Etymology for piste is native to Finnish, with usage spanning everyday language, mathematics, and technical terminology. The form pisteen is one of several genitive forms used to connect a noun to the properties or relations it governs.
