“I used to” and “I’m used to” can be easy to confuse. What’s the difference? Good question. Let me explain with some examples…
We say I used to when we talk about something that we we did in the past, but now we don’t.
“I used to ride the Chuo line everyday.” This means that I rode the Chuo line everyday in the past, but I don’t anymore. I used to ride it everyday.
We say I’m used to when we talk about something that was odd or unusual for us at first, but it is not unusual anymore. We have experience now.
“The Chuo line is very crowded during rush hour, but I am I’m used to it now.” This means that when I rode the Chuo line after I came to Tokyo it was very unusual for me. I had never ridden on such a crowded train. After riding this train for a week it isn’t new or unusual anymore. I have experience riding the train so I’m used to it now.
“I used to be a DJ.” I am not a DJ now but I was before.
“My friend used to live in Russia.” He doesn’t live there now but he did before.
“After 6 years in Tokyo John is used to raw fish .” Raw fish is not new for him anymore. He has experience eating raw fish.
“I used to be a stuntman, so I am used to getting shot!” betting shot is not new for me. I have experience being shot for TV shows and movies. (Lots of experience!!!)
How about you? What did you used to do? What are you used to?
