1530, from M.Fr.
espinache (Fr.
épinard), from O.Prov.
espinarc, which perhaps is via Catalan
espinac, from Andalusian Arabic
isbinakh, from Arabic
isbanakh, from Pers.
aspanakh "spinach." But OED is not convinced the Middle Eastern words are native, and based on the plethora of Romanic forms pronounces the origin "doubtful." Old folk etymology connected the word with L.
spina (see
spine) or with M.L.
Hispanicum olus. For pronunciation, see
cabbage. In 1930s Amer.Eng. colloq. it had a sense of "nonsense, rubbish," based on a famous "New Yorker" cartoon of Dec. 8, 1928.
