onychophagia

Thanks to the Word of the Day, I now know that I’m an onychophage. The word sounds really ugly; I may have to kick the habit for that reason alone.

onychophagia (on-i-ko-FAY-juh, -jee-uh) noun

The practice of biting one’s nails.

[From Greek onycho-, from onyx (nail) + -phagia (eating).]
