History Permalink

Pronunciation

  • IPA: /ˈbɪl.i/[1]

billy1 club; male goat

Confidence
Uncertain
Formation
Eponym
First attested
1795

Etymology

The club is probably from Billy, a pet form of the name William,[2][3][4][5] which, like jack, jimmy and jenny, was given to various implements and machines from 1795;[2][3] Barnhart notes billy as a common appellation from about 1500.[2] Etymonline also compares French bille “a short, stout stick” (see billet).[3]

Earliest recorded meaning

A slubbing machine, used in preparing wool: 1795 in MWU and the late 18th century in the SOED;[4][6] the OED also has a highwayman's club or bludgeon from 1795.[7]

Semantic evolution

In American burglars' slang a billy was a crowbar in 1848,[2][3] and a policeman's club, or billy club, from 1856.[2][3] The billy goat, a male goat, is from 1849 in the OED and the mid-19th century in the SOED.[7][6]

billy2 camp kettle

Confidence
Uncertain
First attested
1839

Etymology

The Australian camp kettle is of uncertain origin.[6] Collins and the ANDC take it from the Scots billypot, a cooking utensil, and the ANDC rejects links with billabong and with tins of bouilli beef;[5][8] MWU takes it as probably a back-formation from billycan,[4] the NODE and SOED suggest an Aboriginal word billa “water”,[9][6] and Morris derived it from the name Billy.[10]

Earliest recorded meaning

A cylindrical tin can with a lid and wire handle, used for boiling water outdoors: 1839 in the OED and MWU, 1849 in the ANDC.[7][4][8]

Semantic evolution

According to Morris, about 1850 the billy replaced the bushman's quart pot, because of its handle and lid.[10] To boil the billy is to make tea, and billy tea is tea made in one.[5][6]

Timeline

  • 1839 – a camp kettle.[7][4]
  • c. 1850 – replaces the quart pot.[10]

Modern meaning

Noun

  1. (chiefly Australia and New Zealand) A metal can with a lid and handle, used for boiling water or cooking over a campfire; a billycan.
  • billycan
  • billy goat
  • billy club
  • William

Usage notes

In Scots and northern English, billy also meant a comrade or companion, from about 1505, or a brother; the origin of this word is unknown.[7][6][11]
