1911 Encyclopædia Britannica/Comity
COMITY (from the Lat. comitas, courtesy, from cemis, friendly, courteous), friendly or courteous behaviour; a term particularly used in international law, in the phrase “comity of nations,” for the courtesy of nations towards each other. This has been held by some authorities to be the basis for the recognition by courts of law of the judgments and rules of law of foreign tribunals (see International Law, Private). “Comity of nations” is sometimes wrongly used, from a confusion with the Latin comes, a companion, for the whole body or company of nations practising such international courtesy.
