Word History

Etymology

borrowed from New Latin, going back to Latin vāgīna "scabbard, sheath," of uncertain origin

Note: Latin vāgīna as an anatomical term does not appear to be earlier than the sixteenth century, though Roman use of the word as a sexual metaphor is as old as Plautus's comedy Pseudolus ("… quom tu ibas simul, conveniebatne in vaginam tuum machaera militis?" - "… when you were going with him, did the soldier's sword fit in your scabbard?"). Latin vāgīna has been compared with Lithuanian vóžti "to close with a lid or cover, shut" (from Indo-European *u̯eh₂ǵ-?), though a link is doubtful given the vague sense connection and lack of other comparanda. According to Ernout and Meillet (Dictionnaire étymologique de la langue latine: histoire des mots, fourth edition, 1959), "undoubtedly a borrowed technical term" ("terme technique sans doute emprunté").
