c.1200, "unmarried or chaste woman noted for religious piety and having a position of reverence in the Church," from Old French virgine, from Latin virginem (nominative virgo) "maiden, unwedded girl or woman," also an adj., "fresh, unused," probably related to virga "young shoot." For sense evolution, cf. Greek talis "a marriageable girl," cognate with Latin talea "rod, stick, bar." Meaning "young woman in a state of inviolate chastity" is recorded from c.1300. Also applied since early 14c. to a chaste man. Meaning "naive or inexperienced person" is attested from 1953. The adj. is recorded from 1550s in the literal sense; figurative sense of "pure, untainted" is attested from c.1300.
