Pronunciation

Forms

équin (feminine équine, masculine plural équins, feminine plural équines)[1]

Etymology

It is borrowed from Latin equīnus (“of horses”),[2][1] from Latin equus (“horse”).[3][4][5]

Earliest recorded meaning

It is first found in 1509 in O. de Saint-Gelais's translation of the Aeneid, meaning “of the horse”.[2][6]

Semantic evolution

The Grand Robert and the Petit Robert date it before 1502.[3][4] It remained a learned word, used mainly in veterinary science (virus d'origine équine, encéphalite équine).[2] In human medicine pied équin names a foot held stretched in line with the leg, so that only its tip rests on the ground, as a horse stands on its hoof;[2][5] the GLLF dates this sense to Flaubert in 1857, who also used équin alone as a noun in Madame Bovary.[6][2]

Timeline

  • 1509 – Used by O. de Saint-Gelais in his Eneïde.[2]
