I found this on another site. Hopefully for both our benefits...
Used as an adjective. Use to be + used to. This means to be accustomed to. For example- I can study with the TV on. I am used to it. It means I am accustomed, adjusted, or don't mind having the TV play while I'm studying.
Or another example- Tim had a hard time living in Tokyo. He wasn't used to so many people. Tim didn't have experience being with big crowds of people before.
Used as a verb. Use to + verb is a regular verb and means something that happened but doesn't happen any more. It uses -ed to show past tense. But since it always means something that happened in the past, it should always use past tense. For example- I used to go to school in Paris. (I went to school there before, but now I don't.) Or, When Joshua was a child, he used to climb trees. (Now he doesn't climb trees.)
Remember, we always use this word when talking about the past. So when do you use use to without the d at the end? When the base form of the verb is used. Look at these examples- She didn't use to swim before noon. (Now she does swim before noon.) Or Did your father use to ride a horse? In these cases the past tense is shown with the did and didn't.
