Synonym discussion
Sense: noun/1
All of these hold hair, but they grip it differently. A hair clip has a hinged part that springs shut, so it presses onto a thick section of hair and is easy to open with one hand. A hairpin is a thin wire bent into a U-shape that you simply slide in; it holds less and slips out more easily. In American English, a barrette is usually a wider, decorative clip worn on the side of the head, while a bobby pin is a small flat pin with a tight bend that keeps short pieces flat against the head. So you might reach for a hair clip to gather a ponytail quickly, but choose a bobby pin to tuck a single loose strand neatly behind your ear.
Etymology
A transparent compound of 'hair' (the threads growing on the head, from Old English hǣr) and 'clip' (something that grips, from Old English clyppan meaning to hold or embrace). The word simply names a small gripping object for the hair, and came into common use as mass-produced hair accessories spread in the twentieth century.
