Punctual \Punc"tu*al\, a. [F. ponctuel (cf. Sp. puntual, It.
   puntuale), from L. punctum point. See {Point}.]
   1. Consisting in a point; limited to a point; unextended.
      [R.] ``This punctual spot.'' --Milton.

            The theory of the punctual existence of the soul. --
                                                  Krauth.

   2. Observant of nice points; punctilious; precise.

            Punctual to tediousness in all that he relates. --
                                                  Bp. Burnet.

            So much on punctual niceties they stand. --C. Pitt.

      an appointed time; precise; prompt; as, a punctual man; a
      punctual payment. ``The race of the undeviating and
      punctual sun.'' --Cowper.

            These sharp strokes [of a pendulum], with their
            inexorably steady intersections, so agree with our
            successive thoughts that they seem like the punctual
            stops counting off our very souls into the past. --
                                                  J. Martineau.
