Using "used to" for past habits and states

"Used to" is a common expression used to talk about past habits, states, or actions that were regular or true in the past but are no longer the case in the present. It is used to describe activities or conditions that occurred repeatedly or continuously over a period of time in the past. The structure "used to" is followed by the base form of the verb. Here are some examples of using "used to" for past habits and states:

Past Habits:
