\In`co*her"ence\, Incoherency \In`co*her"en*cy\, n.
[Cf. F. incoh['e]rence.]
1. The quality or state of being incoherent; want of
   coherence; want of cohesion or adherence. --Boyle.
2. Want of connection; incongruity; inconsistency; want of
   agreement or dependence of one part on another; as, the
   incoherence of arguments, facts, etc.
         Incoherences in matter, and suppositions without
         proofs, put handsomely together, are apt to pass for
         strong reason.                        --Locke.
3. That which is incoherent.
         Crude incoherencies . . . and nauseous tautologies.
