SINGLE (3)

Sin″gle, v. i. To take the irrregular gait called single-foot;- said of a horse. See Single-foot. Many very fleet horses, when overdriven, adopt a disagreeable gait, which seems to be a cross between a pace and a trot, in which the two legs of one side are raised almost but not quite, simultaneously. Such horses are said to single, or to be single-footed. W. S. Clark.
