Words related to broach
"silken fabric variegated with gold and silver or otherwise ornamented," 1560s, from Spanish brocado, corresponding to Italian broccato "embossed cloth," originally past participle of broccare "to stud, set with nails," from brocco (Spanish broca) "small nail," from Latin broccus "projecting, pointed" (see broach (n.)).
mid-14c. (mid-13c. in surnames), "commercial agent, factor," also "an agent in sordid business," from Anglo-French brocour "small trader," from abrokur "retailer of wine, tapster;" perhaps from Portuguese alborcar "barter," but more likely from Old French brocheor, from brochier "to broach, tap, pierce (a keg)," from broche (Old North French broke, broque) "pointed tool" (see broach (n.)), with an original sense of "wine dealer," hence "retailer, middleman, agent." In Middle English, used contemptuously of peddlers and pimps, "one who buys and sells public office" (late 14c. in Anglo-French), "intermediary in love or marriage" (late 14c.).
also broncho, "untamed or half-tamed horse of the American Southwest," 1850, American English, apparently from a noun use of Spanish bronco (adj.) "rough, rude," originally a noun meaning "a knot in wood," perhaps from Vulgar Latin *bruncus "a knot, projection," apparently from a cross of Latin broccus "projecting" (see broach (n.)) + truncus "trunk of a tree" (see trunk (n.1)). Bronco-buster is attested from 1886.
