insolent, Insulting. Insolent, in its primitive sense, simply denoted unusual; and to act insolently was to act in violation of the established rules of social intercourse. He who did this was insolent; and thus the word became one of the most offensive in our language, indicating gross disregard for the feelings of others. Insulting denotes a personal attack, either in words or actions, indicative either of scorn or triumph. Compare Impertinent, Affront, Impudence.
