I used to and I’m used to look almost the same, but they mean very different things. I used to talks about a past habit or past situation that is usually not true now. I’m used to means something feels normal, familiar, or not strange to you now.
Fast answer: Use I used to + base verb for the past: I used to play tennis. Use I’m used to + noun / -ing verb for familiarity: I’m used to early meetings. Never write I’m used to wake up early.
What Does “I Used To” Mean?
I used to means something was true in the past, but it is not true now, or it is no longer your regular habit. It is followed by the base form of a verb, such as live, work, play, eat, or study.
