Origin
Late Middle English; earliest use found in Guy de Chauliac's Grande Chirurgie. From post-classical Latin nenufar water lily from Arabic naynūfar (also as nīnūfar), probably transmission error for nīlūfar from Persian nīlūfar, nīlūpar, also nīlūfal, nīlūpal from Sanskrit nīlotpala blue lotus from nīla dark blue + utpala lotus, water-lily. Compare French nénufar, Spanish nenúfar, Italian nenufaro.
