FromMiddle Englishalabastre, fromOld Frenchalabastre, fromLatinalabaster(“box for perfumes or unguents”), fromAncient Greekἀλάβαστρος(alábastros), from earlierἀλάβαστος(alábastos,“vase without handles for storing perfumes”). This may further derive fromEgyptianꜥj-r-bꜣstjt(“vessel of the Egyptian goddessBast”). The Latin suffix-aster is unrelated, but may have influenced the spelling of the borrowing from Ancient Greek (whence a direct loan could have been rendered as*alabastrus).
