displease

To displease somebody is to annoy them by not being what they wanted. A meal that displeases a fussy guest.

It is more formal and more restrained than annoy, and it carries a whiff of somebody in authority being let down — a king displeased with his court, a manager displeased with the figures. The past participle is where you will meet it most: he looked displeased, she was clearly displeased. That is a mild, controlled anger, the kind that shows in a face rather than a raised voice. Take the dis- away and you have its exact opposite.
