Meaning

noun East Indian annual erect herb; source of sesame seed or benniseed and sesame oil

originFrom late Middle English sisamie, from Latin sīsamum, sēsamum, from Ancient Greek σήσαμον (sḗsamon), from Aramaic שושמא (šūššmā), shortening of שומשומא (šumššumā), from Akkadian 𒊭𒈦𒌑𒈬 (šamaššammū, “oil plant”), compound of 𒉌𒄑 (šaman, “oil”) and 𒌑 (šammum, “plant”). The modern pronunciation is perhaps influenced by (transliterations of) Greek σησάμη (sisámi). Doublet of sesamum.
