Pronunciation

Etymology

It is of unknown origin.[2][3] The noun and verb appear in the 1590s together, at first in the slang of petty criminals.[3][4] It may be a shortening of abet, in an obsolete noun sense “instigation, support”,[4][5][3] or from obsolete beet “to make good, improve”, from Old English bētan, related to better, if betting was thought of as “improving” a contest.[6][3] A link with Middle English bet “advantage”, from the old comparative of well, has not been established.[6]

Earliest recorded meaning

The noun: 1592.[6][7] The verb: 1597, in Shakespeare's Henry IV, Part 2.[6][8]

Semantic evolution

The intransitive verb, “to lay a wager”, is from about 1600,[3] and betting is in Shakespeare's Henry V (1599).[6] The thing wagered is from 1796.[3] American slang assertions followed: bet your life (1848), bet your boots (1856) and you bet “be assured”, by 1857, said to be California slang.[3] Betcha is from 1922.[8] In many dialects of Scotland, Ireland and England bet was a past tense of beat.[9]
