Etymology

Origin of bar1

First recorded in 1175–1225; Middle English barre, barr, bar, from Old French, from unattested Vulgar Latin barra “rod,” of obscure, perhaps pre-Latin, origin

Origin of bar2

First recorded in 1770–80; from Louisiana French bère, baire, apparently representing dialect pronunciation of French barre “barrier, rod”; see bar 1

Origin of bar3

First recorded in 1900–05; from Greek báros “weight”; cf. barometer, isobar

Explanation

If you bar a college student from entering a bar because he's too young to drink, it means that you prevent him from going into an establishment that serves alcoholic beverages. Bar is one of those handy words with many different meanings. There's the kind of bar where you order coffee or a drink. There is also the bar that a bartender keeps close at hand in case she needs a weapon when patrons get rowdy — like a long piece of metal. And when you bar something, you make it inaccessible in some way. The word bar comes from the French word barre, which means "beam, gate, or barrier."
