[Middle English usen, from Old French user, from Vulgar Latin *ūsāre, frequentative of Latin ūtī. N., Middle English, from Old French us, from Latin ūsus, from past participle of ūtī.]
Usage Note: The verb use is used in the past tense with an infinitive to indicate a past condition or habitual practice: We used to live in that house. Because the -d in used has merged with the t of to and is not pronounced in these constructions, people sometimes mistakenly leave it out when writing. Thus it is incorrect to write We use to play tennis. When do occurs with this form of use in negative statements and in questions, the situation is reversed, and use to (not used to) is correct: You did not use to play on that team. Didn't she use to work for your company?
