has = has got / had got = had

[Xyz]

Is it correct to say that has, have, had sentences can be changed to has got, have got, had got sentences and vice versa?
Eg:
I have a pencil = I have got a pencil
I had got 2 pencils = I had 2 pencils.

[Our Tort System]

These are right:
I have a pencil = I have got a pencil
I had 2 pencils.

"I had got a pencil" does not mean "I had a pencil", it means that you had come into possession of a pencil (somebody had given you a pencil).

I think we don't use "have got" in the past tense, so we can't say "I had got 2 pencils", in stead you can use "had": "I had two pencils"

You can indeed say "had got," but it will make it sound just as Tort said.

Both are possible in American English.

I had gotten two pencils. - This most likely means you have actively sought and acquired or just received them.
I had got two pencils. - If this were present perfect, "got" would mean you just had them in your possession. Almost nobody would bother with the past perfect in this case, so I tend to think it will be interpreted as "I actively sought and acquired two pencils."

The first sentence sounds better without "got."

[Thuynguyen]

But I'm talking about the past tense, not the past perfect. So "I had got 2 pencils" cannot be equal to "I had 2 pencils".
Waiting for your prompt reply :)

"Had got" is the past perfect, my friend.

Past perfect = had + past participle.

Had got
Had run
Had talked
Had bought
Had cut
Had made

If you re-read my post, you will see that I don't find them equivalent.

However, with the present perfect, these two ideas can be:

Does anybody have a pen? I have a pen.
Does anybody have a pen? I have got a pen.

The difference is that almost nobody would express the idea of simple possession in such a sentence with the past perfect, so I tend to think the use of it would almost always be interpreted differently.
