Selected source glosses provide context, not a complete modern definition inventory

Inherited from Middle English tansy, tansey, syncopic forms of earlier tanesie, tanesei, from Old French tanesie, tanoisie, tanasie, tanaisie, from Medieval Latin tanacetum, atanacetum, attested since the 8th century, of obscure origin, speculated from Ancient Greek ἀθανασία (athanasía, “immortality”) owing to hallucinations from the thujone in the plant, else from taenia (“tapeworm”) due to its primary use against parasites by which reason it is called in Arabic حَشِيشَة الدُود (ḥašīša ad-dūd, literally “worm herb”), otherwise a Berber borrowing like tagetes.

Where this record stops

This page does not supply an independently verified sound-change sequence, first-use manuscript or complete family tree unless a cited analysis explicitly establishes one. Missing detail here is a limit of this record—not a claim that humanity knows nothing more.

An older meaning does not determine what a word must mean today. Follow the sources, preserve disagreements, and keep ancestry separate from interpretation.
