    Note

    The sense every other one grows from: Old English hors, probably traced back to an Indo-European word for a vehicle, from a root meaning "to run". That would make it a distant doublet of car. It combines freely by job, as with dray-horses, carriage-horses and cart-horses in Walter Besant's The Ivory Gate (1892). Samuel Johnson's Dictionary of 1755 defined oats as a grain given to horses in England but feeding the people in Scotland.
