\Com"i*ty\, n.; pl. {Comities}. [L. comitas, fr. comis
courteous, kind.]
Mildness and suavity of manners; courtesy between equals;
friendly civility; as, comity of manners; the comity of
States.
{Comity of nations} (International Law), the courtesy by
   which nations recognize within their own territory, or in
   their courts, the peculiar institutions of another nation
   or the rights and privileges acquired by its citizens in
   their own land. By some authorities private international
   law rests on this comity, but the better opinion is that
   it is part of the common law of the land, and hence is
   obligatory as law.
Syn: Civility; good breeding; courtesy; good will.
