Kääntely

Kääntely is a Finnish noun that denotes the act or process of turning, rotating, or twisting. It is formed from the verb kääntää (to turn, to translate) and the nominal suffix -ly used to express ongoing action or process. In practical terms, kääntely is used in contexts such as metalworking and machining to describe turning operations, where a lathe or other machine rotates a workpiece to shape it by removing material. The term emphasizes the motion of turning around an axis rather than the completion of the shape.

In general conversation, kääntely may be used to describe turning or twisting of objects, as well as figurative uses where a situation is turned around, though for linguistic translation the standard term is käännös. The related nouns include kääntö (a turn, a reversal) and käännös (a translation). The word is primarily used in Finnish-language technical or descriptive writing; outside technical contexts, more common synonyms or phrasing may be used.
