  Usage: -- Idle, Indolent, Lazy. A propensity to inaction is expressed by each of these words; they differ in the cause and degree of this characteristic. Indolent denotes an habitual love to ease, a settled dislike of movement or effort; idle is opposed to busy, and denotes a dislike of continuous exertion. Lazy is a stronger and more contemptuous term than indolent.

  I·dle, v. t. To spend in idleness; to waste; to consume; -- often followed by away; as, to idle away an hour a day.
