Pronunciation
- IPA: /ˈkɔːkəs/ (UK); /ˈkɔkəs/, /ˈkɑkəs/ (US)[1]
Etymology
An American English word of uncertain origin.[2][3][4] It may come from the name of the Caucus Club of colonial Boston (1760s),[5][6][3] perhaps from Medieval Latin caucus “drinking vessel”, from Greek kaûkos “cup”.[5][6][3] Another suggestion is a Virginia Algonquian word caucauasu “elder, adviser”,[4][3] which Random House considers less probable.[6] The old guess caulkers' meeting is dismissed by the OED.[3]
Earliest recorded meaning
In the United States, a private meeting of the leaders or members of a political party before an election, to choose candidates or agree on policy (1763).[7][2][4][3] Barnhart records an earlier form Corcus from 1745.[4]
Semantic evolution
The word was long a Boston cant term whose origin even contemporaries could not explain.[3] In British newspapers from 1878 it was used, often opprobriously, of a party committee that tried to direct elections.[7][5] In modern American usage it also names a group within a legislature organized to promote a particular interest.[5][6][1] The verb is dated 1788 by Merriam-Webster (with caucusing attested then) and 1850 by Barnhart and Etymonline.[2][3][4][7]
