hackney

 
Pronunciation: /ˈhakni/

noun (plural hackneys)

chiefly historical
  • a horse or pony of a light breed with a high-stepping trot, used in harness.
  • [usually as modifier] a horse-drawn vehicle kept for hire: a hackney coach

Origin:

Middle English: probably from Hackney in East London, where horses were pastured. The term originally denoted an ordinary riding horse (as opposed to a war horse or draught horse), especially one available for hire: hence hackney carriage or coach, and the verb hackney meaning 'use (a horse) for general purposes', later 'make commonplace by overuse' (see hackneyed)
