A huntress is a female hunter. You meet her most often in myths, poems, paintings, and games: a goddess with a bow, a woman tracking an animal in a forest. In everyday talk, many people now just say hunter for a woman too. The old ending -ess marks a female role, and some speakers feel it makes the woman a special extra case, so they drop it. Huntress is also used as a girl’s name, the feminine form of Hunter. None of this makes the word wrong; it tells you which room it lives in now — stories, names, and older writing more than a news report about a real hunting licence.
