ympyröihin

Ympyröihin is a Finnish word that functions as the illative plural form of ympyrä, the noun for circle. It expresses direction toward or into multiple circles. In Finnish grammar, the illative case marks movement toward a destination, and the plural illative is formed by adding the suffix -ihin to the stem ympyrö- to yield ympyröihin.

Usage of ympyröihin occurs in contexts describing spatial movement involving several circular elements, such as mathematical descriptions, architectural plans, or graphic designs that incorporate multiple circles. It contrasts with ympyrään, the singular illative form, and with ympyröissä, the plural inessive meaning “in the circles.” The plural illative form is more common in technical or descriptive language than in everyday speech.

Etymology and related forms: ympyröihin is derived from the noun ympyrä with the illative plural suffix -ihin. Related forms include ympyrä (circle) in other cases, such as ympyrän (genitive singular) and ympyröiden (genitive plural). The word belongs to a broader set of Finnish noun forms that mark destination or direction with illative cases, reflecting the language’s rich case system.
