Pöörlevast

Pöörlevast is the elative singular form of the Estonian adjective pöörlev, meaning rotating or turning. In Estonian grammar, the elative case, marked by the suffix -st, is used to express movement from or origin. When an adjective takes an elative form, it modifies a noun in the elative, indicating relation to a process or source. Therefore, pöörlevast is used to say “from the rotating …” or “of the rotating …” in contexts such as technical descriptions.

In practical use, pöörlevast typically appears in engineering and mechanical texts, where rotation is a defining property of components or systems. Examples include phrases like pöörlevast mehhanismist (from the rotating mechanism) and pöörlevast osast (from the rotating part). These constructions help specify which part or process is associated with rotation, enabling precise reference in manuals, reports, and technical documentation.

Etymology and related terms: pöörlev derives from the concept of rotation, linked to the noun pöörlemine (rotation) and the verb pöörlema (to rotate). Related Estonian terms include pöörlemine and pöörlev (rotating).
