Tansy is the name of a flowering plant that has also been used as a medicinal herb. The name comes from French tanesie, an aphetic form of athanasie via Ancient Greek athanasia meaning “immortality”, made up from Greek negative prefix a- and thantos (death; corpse). Another possible meaning behind the name I’ve seen listed is that it comes from Vulgar Latin *tanacēta via Late Latin tanacetum meaning “wormwood”.

Tansy is also a surname, a variant spelling of Tansey, an Irish and Scottish surname, the anglicized form of Gaelic Mac an Tánaiste meaning “son of the tanist” or “son of the second-in-command”, tánaiste an Irish word meaning “tanist, heir presumptive, second-in-command”.

Origin: Proto-Indo-European
