Capitulate \Ca*pit"u*late\, v. i. [imp. & p. p. {Capitulated};
   p. pr. & vb. n. {Capitulating}.] [LL. capitulatus, p. p. of
   capitulare to capitulate: cf. F. capituler. See {Capitular},
   n.]
   1. To settle or draw up the heads or terms of an agreement,
      as in chapters or articles; to agree. [Obs.]

            There capitulates with the king . . . to take to
            wife his daughter Mary.               --Heylin.

            There is no reason why the reducing of any agreement
            to certain heads or capitula should not be called to
            capitulate.                           --Trench.

   2. To surrender on terms agreed upon (usually, drawn up under
      several heads); as, an army or a garrison capitulates.

            The Irish, after holding out a week, capitulated.
                                                  --Macaulay.
