Pööretest

Pööretest is the plural elative form of the Estonian noun pööre, which can mean a rotation or turn in a mechanical or geometric sense and also a political or historical revolution or turning point. The form pööretest is used when the speaker refers to origin or source arising from multiple turns or revolutions. It is a grammatical case used in Estonian to indicate movement away from or from within several revolutions or cycles.

In practice, pööretest appears mainly in formal or technical writing, such as physics, engineering descriptions of gears, or historiography when discussing several revolutions of an object or a sequence of events. It is less common in everyday speech, where speakers might opt for broader wording or paraphrase to avoid the rare plurally inflected form.

Etymology and morphology: pööretest is derived from pööre with the plural elative ending -test. This pattern aligns with other Estonian plural elative forms formed from nouns ending in -e, used to express origin from multiple items.
