Forms

grégeois (feminine grégeoise, masculine plural grégeois, feminine plural grégeoises)[1] Old French grezeiz, grezois, grigeois and gregois.[2][3][4]

Etymology

It is inherited from Old French grezois (“Greek”), also grezeiz (about 1130), altered in the 12th century, and the Old French word is inherited from Vulgar Latin *graeciscus, formed from graecus (“Greek”) with the suffix -iscus.[2][3][5][6] The Grand Lexique traces this suffix to Germanic.[7] Wiktionary also allows a French formation from Old French grieu “Greek” with the suffix -ois.[1] Littré had derived it from Latin graecensis.[8]

Cognate with Old Occitan grezesc and Romanian grecesc.[3][5][1] Rey thinks that grisou “firedamp” is probably an altered form of the same word.[3]

Earliest recorded meaning

Before 1188, grigeois is used as a noun for the Greek language in Partonopeus de Blois.[2][3]

Semantic evolution

The adjective meant simply “Greek”, but it survived mainly in feu grégeois “Greek fire”, recorded as feu grezeis about 1160 and as feu gregois about 1190.[2][3][7] This incendiary mixture, used by the Byzantines above all in sea battles, became known to Western Europeans during the Third Crusade.[3][5] La Bruyère used feu grégeois figuratively for a flash of wit before 1696.[7] The plain sense “Greek” returns as a deliberate archaism in Chénier and later writers.[7]
