Origin & History of “broker”

Broker has no connection with the past tense of break. It comes from Anglo-Norman brocour ‘small trader’, but its ultimate origin is not clear. A variant Anglo-Norman form abrocour has fuelled speculation as to a link with Spanish alboroque ‘sealing of a bargain’ and Portuguese alborcar ‘barter’, which are presumably of Arabic origin (the al- representing the Arabic definite article); but other etymologists have sought to link the word with broach, as if the underlying sense were ‘someone who sells wine from (that is, by broaching) the cask’, and hence any ‘retailer’.
