pisteessä

Pisteessä is a Finnish locative form derived from the noun piste, meaning point or dot. The word combines piste with the inessive suffix -ssä to express location inside or at a particular point, corresponding roughly to “in the point” or “at the point” in English. It is used to indicate location within a physical space or within an abstract context such as mathematics.

Morphology and usage context: In Finnish, pisteessä follows the standard noun inflection pattern, with other case forms including pisteestä (from the point), pisteelle (to/onto the point), pisteellä (at the point), and pisteen (the point’s). The primary function of pisteessä is to specify where something is located or happens, especially in formal, technical, or mathematical language.

Applications: In mathematics and related disciplines, pisteessä is commonly used to describe values or properties at a specific point. For example, a sentence might read: F on määritelty pisteessä x0, meaning “F is defined at the point x0,” or “the function is continuous at the point x0.” In practical contexts such as mapping or plotting, it can denote the position of a datum or feature at a given point, often in combination with other spatial terms.

Etymology: The word is formed from piste (point) + the locative inessive suffix -ssä, reflecting Finnish patterns of noun declension. Pisteessä thus represents a precise, location-based usage of the foundational word piste.
