Pronunciation

  • IPA: /bɹɑːs/ (UK); /bɹæs/ (US)[1]

Etymology

It is Middle English bras, inherited from Old English bræs (“brass, bronze”),[2][3][4] of unknown origin.[4][5][3] Barnhart and Hoad compare Old Frisian bres, copper, and Middle Low German bras, metal;[2][4] Etymonline calls it a mystery word with no known cognates beyond English, perhaps akin to French brasser, to brew, because brass is an alloy.[3] Merriam-Webster suggests a West Germanic word perhaps borrowed from a source in southwest Asia.[6]

Earliest recorded meaning

An alloy of copper, in England usually with tin, now called bronze: about 1000, in Ælfric's Grammar.[2][3]

Semantic evolution

The modern alloy of about two parts copper to one of zinc is a later use;[3][7] the use of brass in Bible translations probably means bronze, since brass was unknown in early antiquity.[3] As a type of hardness, durability or insensibility it is from the late 14th century (1388).[3][7] A memorial tablet of brass is from 1613.[7] Effrontery, impudence, is from the 1620s,[3] and brassy, forward in manner, from 1576.[2] The brass instruments of a band are a later sense,[3][8] brass band is from 1827,[3] and the slang sense of high officials, from their insignia, from 1899.[3] Getting down to brass tacks is from 1897,[3] and the brass monkey of cold weather from 1843.[3]
