Explicit \Ex"pli*cit\ [LL., an abbreviation of explicitus (est
   liber) the book (which anciently was a roll of parchment) is
   unfolded (and, of course, ``finished''). See {Explicit}, a.]
   A word formerly used (as finis is now) at the conclusion of a
   book to indicate the end.

Explicit \Ex*plic"it\, a. [L. explicitus; p. p. of explicare to
   unfold: cf. F. explicite. See {Explicate}, {Exploit}.]
   1. Not implied merely, or conveyed by implication; distinctly
      stated; plain in language; open to the understanding;
      clear; not obscure or ambiguous; express; unequivocal; as,
      an explicit declaration.

            The language of the charter was too explicit to
            admit of a doubt.                     --Bancroft.

   2. Having no disguised meaning or reservation; unreserved;
      outspoken; -- applied to persons; as, he was earnest and
      explicit in his statement.

   {Explicit function}. (Math.) See under {Function}.

   Syn: Express; clear; plain; open; unreserved; unambiguous.

   Usage: {Explicit}, {Express}. Explicit denotes a setting
          forth in the plainest language, so that the meaning
          can not be misunderstood; as, an explicit promise.
          Express is stronger than explicit: it adds force to
          clearness. An express promise or engagement is not
          only unambiguous, but stands out in bold relief, with
          the most binding hold on the conscience. An explicit
          statement; a clear and explicit notion; explicit
          direction; no words can be more explicit. An explicit
          command; an express prohibition. ``An express
          declaration goes forcibly and directly to the point.
          An explicit declaration leaves nothing ambiguous.''
          --C. J. Smith.
