use to

Etymology
From +.

Verb

 * 1)   formerly (and habitually or repeatedly) be accustomed to.

Usage notes

 * Use to is now generally only used in the past tense (used to), although use to is still standard with did, as in did I use to do that? or he did not use to do that. In other cases, such as I use to go to the fair every year, it is considered an error (but a common one, influenced by the near- or exact- homophony of the two forms) and should instead exist in the past tense form used to.
