Expressing a different opinion or failing to match or correspond with something.
From Old French 'desagreier,' combining 'des-' (not) with 'aggreier' (to please or suit). The prefix 'dis-' means 'not' in Latin, and 'agree' comes from Latin 'gratus' (pleasing).
The root meaning of 'agree' is literally 'to be pleasing'—so when you disagree, you're saying something isn't pleasing or satisfying, which is why disagreements feel uncomfortable!
