Most learners confuse "used to" with "used to do" or forget its correct form in negative and interrogative sentences. I’ll clarify all of this below.

How to Use "Used To" Correctly: A Step-by-Step Breakdown

When constructing sentences with "used to," it’s essential to understand the different forms it can take: affirmative, negative, and question. Let’s break these down with clarity.

Affirmative Sentences

  • Structure: Subject + used to + base verb
  • Example: I used to play tennis every weekend.

Use "used to" to describe actions that were habitual in the past but no longer happen.

Negative Sentences

  • Structure: Subject + didn’t + use to + base verb
  • Example: She didn’t use to like spicy food.
    Note: Although many native speakers say "use to" in negatives, technically it should be "didn’t use to,” but "used to" is also accepted in informal speech.

Interrogative Sentences

  • Structure: Did + subject + use to + base verb?
  • Example: Did you use to live in New York?

Key Points to Remember:

  • In questions and negatives, "use" becomes "use to" (without the "d" after "did").
  • "Used to" in affirmative is consistent and easy to remember.

Common Pitfalls:

Mistake Correct Form Explanation
Did you used to? Did you use to? Omit "d" after "use" in questions.
She didn’t used to like it. She didn’t use to like it. Same as above, proper negative form.
