I used to to cook every day - Eu costumava cozinhar todos os dias
We use the expression used to to communicate a finished habit or a repeated situation in the past:
In the negative, there are two possible forms: did not use to (common in Spoken English) and used not to (more formal and less common):
Used to is not commonly used in questions. The structure is: 'Did you use to?' or 'Did there use to be?'. Instead of using these forms, it is common to just use the past simple:
Did you play tennis? Did you use to play tennis?
Were there shops here? Did there use to be shops here?
