Jun-godSo, "got" in last sentence is not a past of the verb "get", it is same meaning as "have" in first sentence
Hi Jun-god,
yes, "got" is sometimes equivalent to "have", not only in the idiom "have got to".
I got to do it = I have to do it ---> But usually pronounced
I gotta do it.It comes from
I've got to do it, without
've. Read CalifJim's post, he explained that.
The past is "had to". I don't think "had got to" is in use in American English.
Also, "got" instead of "have" can be used for possession:
Hey, look what I got.
I got no money.
What do you got? --> Waddaya got? - Watcha got?I am not going to tell you when or where these forms are appropriate, since you said you have a private teacher... I'm sure they'll tell you about informal English.
