To advise against something; to urge someone not to do something; to dissuade.
From Latin dehortari, combining de- (away) + hortari (to encourage or urge). The opposite of 'exhort,' meaning to strongly urge someone to do something.
While 'exhort' is common (think of coaches exhorting their teams), dehort is its forgotten opposite—but it perfectly captures when someone earnestly begs you NOT to do something.
