/əˈkɔrəs/,

/ˈækərəs/

Forms: late Middle English acharus, late Middle English achorus, 1500s– acorus.

Origin: A borrowing from Latin. Etymons: Latin acorus, acoros, acoron.

Etymology: < post-classical Latin acorus, masculine (in an undated glossary; 4th cent. as acoros), variant of classical Latin acoron, acorum (neuter) sweet flag or yellow flag < Hellenistic Greek ἄκορον yellow flag (Dioscorides), associated by ancient etymologists with ancient Greek κόρη pupil of the eye (see coro- comb. form), as the plant was used medicinally to treat inflammation of the eye. Compare Middle French, French acorus (16th cent.), Spanish ácoro (1493; ?c1275 as †acorio), Italian acoro (end of the 14th cent.).

Originally: the plant sweet flag, Acorus calamus. In later use: any plant of the genus Acorus (family Acoraceae), the members of which are rushlike flowering plants with inconspicuous flowers, native chiefly to wetlands in Europe and Asia. Also (in form Acorus): the genus itself.Valid publication of the genus name: Linnaeus Species plantarum (1753) I. 324.
