Constraint \Con*straint"\, n. [OF. constrainte, F. constrainte.]
   The act of constraining, or the state of being constrained;
   that which compels to, or restrains from, action; compulsion;
   restraint; necessity.

         Long imprisonment and hard constraint.   --Spenser.

         Not by constraint, but by my choice, I came. --Dryden.

   Syn: Compulsion; violence; necessity; urgency.

   Usage: {Constraint}, {Compulsion}. Constraint implies strong
          binding force; as, the constraint of necessity; the
          constraint of fear. Compulsion implies the exertion of
          some urgent impelling force; as, driven by compulsion.
          The former prevents us from acting agreeably to our
          wishes; the latter forces us to act contrary to our
          will. Compulsion is always produced by some active
          agent; a constraint may be laid upon us by the forms
          of civil society, or by other outward circumstances.
          --Crabb.
