1. The small projection of skin-covered cartilage at the front of the ear.
2. Any of the hairs growing just behind this projection, partially covering the entrance to the ear.
Etymology: late 1600s, from Greek tragos, hairy part of the ear; literally 'goat'.
Therei is also an antitragus, which probably gets its name from its proximity to the tragus, rather than from being less goaty.
