The word's journey begins with the Old English stīweard, a compound literally meaning "house guard" or "hall keeper," which evolved into the general term for a manager of an estate or household. The feminine suffix -ess, entering English via Old French from Latin and ultimately Greek, was productively attached to many agent nouns to specify the female gender. Thus, "stewardess" was formed by directly appending this suffix to "steward," creating a term for a female caretaker or manager. Its specific application to female flight attendants emerged in the 20th century, reflecting the gendered occupational roles of the era, though the term has since become dated in favor of the gender-neutral "flight attendant."
