Word History

Etymology

Noun (1)

Middle English barre, from Anglo-French, from Vulgar Latin *barra

Verb

Middle English barren, borrowed from Anglo-French barrer, derivative of barre bar entry 1

Preposition

derivative of bar entry 2

Noun (2)

borrowed from Greek báros "heaviness, weight, pressure" — more at bar-

Combining form

irregularly from Greek báros "heaviness, weight, pressure," derivative from the base of barýs "heavy" — more at grave entry 2

Note: As Greek báros is a neuter s-stem, it would not regularly produce a compounding form with -o-. In ancient and late classical Greek there appears to be no evidence for a form baro-, though there are a large number of compounds with bary-. The earliest English formation with baro- is probably barometer.
