Hello, there I'm new here. I want to know the difference between these sentences

A: I wanted to thank you

B:I HAVE wanted to thank you


C: She already warned me not to do that

D: She HAS already warned me not to do that

Hello (no comma here) there, I'm new here. I want to know the difference between these sentences.

A: I wanted to thank you.

B:I HAVE wanted to thank you.


C: She already warned me not to do that.

D: She HAS already warned me not to do that.

May I know what difference would there be if I put has/have in the following sentences. (There are no "following sentences" - that refers to sentences that come after the words "following sentences".)

The difference between C and D is simply the tense.
Sentence A is correct.
Sentence B needs something after "thank you".

Something after " Thank you "? like what?

Sorry for double posting, but I wanna make sure.

you say that it's simply the tense. So is C in the past tense and D is in the present?

Thanks a lot. It's crystal clear to me now!

Something after "Thank you"? Like what?

See above. Don't put a space after opening quotation marks or before closing them.

You need something like "I have wanted to thank you for a long time but this is the first time I've had the opportunity to do so".

I see, thanks alot. I wanna ask another thing that's been bothering me. What is the difference in the following sentences

"That hasn't changed since he was little"
"That didn't change since he was little"

What is the difference in these?

I see, thanks [STRIKE]alot[/STRIKE] a lot. I [STRIKE]wanna[/STRIKE] want to ask about another thing that's been bothering me. What is the difference [STRIKE]in[/STRIKE] between the following sentences?

"That hasn't changed since he was little."
"That didn't change since he was little."

What is the difference [STRIKE]in[/STRIKE] between these?

The main difference is that the first is grammatical and the second is not. The past simple doesn't work with "since".
