kääntyvä

Kääntyvä is a Finnish adjective and present active participle derived from the verb kääntyä, meaning to turn, rotate, or bend. It describes something that turns or is capable of turning, i.e., possessing a turning, pivoting, or reversible characteristic. In technical and mechanical contexts the term is used for components or motions that rotate around an axis, for example kääntyvä nivel (swivel joint) or kääntyvä mekanismi (pivoting mechanism). In everyday language it can describe rotating furniture or equipment, although more general terms such as pyörivä are common for simple rotation.

Grammatically, kääntyvä is the present active participle form of kääntyä and functions as an adjective. It agrees with the noun it describes in number and case, for example kääntyvä pöytä (a rotating table) or kääntyvän pöydän jalat (the legs of the rotating table). The noun form related to the verb is kääntyminen (the act or process of turning). The word stands in contrast to synonyms such as pyörivä (rotating), which may be used depending on nuance and context.

Kääntyvä is frequently found in engineering, design, and furniture descriptions, where a part or object is intended to rotate or pivot. It also appears in figurative language to indicate a change in direction or viewpoint. Related terms include kääntyminen and kääntäminen, and the broader concept of rotation is often expressed with words like pyörivä or nivel (joint).
