bar

\ \ [12] The history of bar cannot be traced back very far. Forms in various Romance languages, such as French barre (source of the English verb) and Italian and Spanish barra, point to a Vulgar Latin *barra, but beyond that nothing is known. The original sense of a ‘rail’ or ‘barrier’ has developed various figurative applications over the centuries: in the 14th century to the ‘rail in a court before which a prisoner was arraigned’ (as in ‘prisoner at the bar’); in the 16th century to a ‘partition separating qualified from unqualified lawyers in hall’ (as in ‘call to the bar’); and also in the 16th century to a ‘counter at which drink is served’.

\ \ Related nouns include barrage [19], originally an ‘artificial obstruction in a waterway’, and barrier [14], from Anglo- Norman barrere.
