Pronunciation

  • UK: /ˈhɔːsˌbæk/[1]
  • US: /ˈhɔɹsˌbæk/[1]

Etymology

It is inherited from Middle English horsback, also written hors-bak,[2][3] formed from Middle English hors + bak,[2] that is, horse and back.[4][5][6] The MED derives it from the Middle English phrase hors(es) bak, a horse's back.[3]

Earliest recorded meaning

In the phrase on horseback, riding on a horse: 1390, in John Gower's Confessio Amantis,[4][3][7] late 14th century in Etymonline.[5] Gower describes a knight waiting in ambush upon horse bak.[3]

Semantic evolution

In Middle English the word lived in phrases: at, on or upon horseback for mounted, and to horseback for mounting.[3][4] The noun alone, the back of a horse, is recorded only from 1484 to 1704,[4] and the Shorter Oxford notes that it now survives only in on horseback.[6] Johnson (1755) defined it as "the seat of the rider; the state of being on a horse", quoting Shakespeare.[8] The phrase was shortened to an adverb, horseback for "on horseback", from 1727,[4][2] and to "riding" (1878, in George Eliot).[4] American English used it for a ridge of sand or gravel, a hogback (1851), and for a hasty judgement made without full information (1879);[4][2] miners used it for a bulge of rock into a coal seam (1881).[4][2] Etymonline notes that the Century Dictionary recorded footback as a jocular opposite.[5]
