bar·but(bär′bŭt′) also bar·bute (-byo͞ot′, -bo͞ot′) also bar·bu·ta (-byo͞o′tə, -bo͞o′-)
A style of European helmet from the late Middle Ages, long on the sides and in back to protect the neck, and usually having a T-shaped opening in the front.
[French barbute, ultimately from Italian barbuta, from barba, beard (the helmet being so called because it allowed the wearer's beard to be seen), from Latin; see bhardh-ā- in Indo-European roots.]
