Step \Step\, n. [AS. st[ae]pe. See {Step}, v. i.]
   1. An advance or movement made by one removal of the foot; a
      pace.

   2. A rest, or one of a set of rests, for the foot in
      ascending or descending, as a stair, or a round of a
      ladder.

            The breadth of every single step or stair should be
            never less than one foot.             --Sir H.
                                                  Wotton.

   3. The space passed over by one movement of the foot in
      walking or running; as, one step is generally about three
      feet, but may be more or less. Used also figuratively of
      any kind of progress; as, he improved step by step, or by
      steps.

            To derive two or three general principles of motion
            from phenomena, and afterwards to tell us how the
            properties and actions of all corporeal things
            follow from those manifest principles, would be a
            very great step in philosophy.        --Sir I.
                                                  Newton.

            The reputation of a man depends on the first steps
            he makes in the world.                --Pope.

            Beware of desperate steps. The darkest day, Live
            till to-morrow, will have passed away. --Cowper.

            I have lately taken steps . . . to relieve the old

   10. (Naut.) In general, a framing in wood or iron which is
       intended to receive an upright shaft; specif., a block of
       wood, or a solid platform upon the keelson, supporting
       the heel of the mast.

   11. (Mach.)
       (a) One of a series of offsets, or parts, resembling the
           steps of stairs, as one of the series of parts of a
           cone pulley on which the belt runs.
       (b) A bearing in which the lower extremity of a spindle
           or a vertical shaft revolves.

   12. (Mus.) The intervak between two contiguous degrees of the
       csale.

   Note: The word tone is often used as the name of this
         interval; but there is evident incongruity in using
         tone for indicating the interval between tones. As the
         word scale is derived from the Italian scala, a ladder,
         the intervals may well be called steps.

   13. (Kinematics) A change of position effected by a motion of
       translation. --W. K. Clifford.

   {Back step}, {Half step}, etc. See under {Back}, {Half}, etc.
