Rapeseed is the seed of the rapeseed plant, used to produce oil and meal for food, industrial, and biodiesel applications. In everyday usage, it refers to the seed itself, or to the oil derived from it. The term blends the French rapese, from rapum meaning turnip, with seed, denoting the seed of a cruciferous plant. It is pronounced as two syllables: /ˈreɪ.pəsˌsiːd/ in many dialects, with some variation in stress and vowel quality.
