brooch

the word "brooch" has a fascinating journey from a functional object to a decorative one. it originates from the old french "broche," meaning a pointed tool or a spit for roasting meat, which itself came from the vulgar latin "brocca," a feminine form of the latin adjective "broccus," meaning projecting or pointed. the semantic shift occurred because the decorative pin used to fasten clothing was, in its earliest forms, essentially a large, ornate pointed pin, sharing the core idea of a "pointed object" with its culinary ancestor. over time, as its primary function became ornamental rather than practical, the spelling and pronunciation in english stabilized to "brooch," distinguishing it from the similar-sounding "broach," which retained more of the original "to pierce" or "to open" meanings.

this word is a simplex form. it entered english as a loanword from old french.
