Pronunciation

  • /ˈpeɪbæk/[1]

Etymology

It is formed from English pay + back, after the phrasal verb pay back,[2][3][4] and the OED compares the earlier noun paying back.[2] Dictionary.com takes it as the noun use of the verb phrase.[5]

Earliest recorded meaning

Something repaid or given in return for a service or favour; a reward: 1718, in an Answer to a Late Insolent Libel.[2][6] Etymonline dates the word to 1946,[4] and Dictionary.com to 1955–60.[5]

Semantic evolution

After its early use for a return or reward, the word settled in finance as the return on an investment, especially when it equals the outlay (Etymonline, 1946).[2][4] From 1965 it was also the payback period, the time an investment takes to pay for itself.[2][3] In Australia it named, from 1935, the Aboriginal custom of revenge, or an act of revenge under it,[2] and Green's Dictionary of Slang quotes a similar use of feud revenge from Papua in the 1930s and 1940s.[7] The general sense "retaliation, revenge" followed: Green's has it in American use in 1951, Etymonline by 1957,[7][4] and the OED from 1973.[2]
