      Syn: Employ.

      Usage: Use, Employ. We use a thing, or make use of it, when we derive from it some enjoyment or service. We employ it when we turn that service into a particular channel. We use words to express our general meaning; we employ certain technical terms in reference to a given subject. To make use of, implies passivity in the thing; as, to make use of a pen; and hence there is often a material difference between the two words when applied to persons. To speak of ``making use of another'' generally implies a degrading idea, as if we had used him as a tool; while employ has no such sense. A confidential friend is employed to negotiate; an inferior agent is made use of on an intrigue.

      I would, my son, that thou wouldst use the power Which thy discretion gives thee, to control And manage all.
      --Cowper.

      To study nature will thy time employ: Knowledge and innocence are perfect joy.
      --Dryden.
