wiktionary
From Middle English sysame, 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 influenced by Ancient Greek σησάμη(sēsámē), variant of σήσαμον(sḗsamon). [1]
etymonline
sesame (n.)
early 15c., sisamie, probably from Latin sesamum (nominative sesama), from Greek sesamon (Doric sasamon) "seed or fruit of the sesame plant," a very early borrowing via Phoenician from Late Babylonian *shawash-shammu (compare Assyrian shamash-shammu "sesame," literally "oil-seed"). Medieval Latin had it as sisaminum; Old French as sisamin.
First as a magic password in a 1785 translation of Galland's "Mille et une nuits," where it opens the door of the thieves' den in "Ali Baba and the Forty Thieves." The exact phrase open sesame is attested from 1793 in another translation, current since about 1826.
