Entitled means having a right to something, or expecting one without cause. Entitled to a refund, an entitled attitude, entitled to know.
The two senses pull opposite ways: entitled to something is neutral and legal, and calling a person entitled is an insult. The word also means having a title — a book entitled something — which is the oldest sense of the three.
