The state or quality of being discourteous; lack of courtship or courtly behavior.
Formed from discourt- (from dis- + court) combined with -ship (state or condition of). This is a rare or archaic formation attempting to create a noun describing the condition of being without courtly manners.
This is such a rare word that most dictionaries barely recognize it—it's like scholars invented it logically but then everyone decided 'discourteousness' and 'discourtesy' worked better, so it never caught on!
