Ain't / haven't

[jack]

What do these mean?
1. I ain't never seen anyone like you.
2. I haven't seen anyone like you.

(1) In this sentence, 'ain't' is substandard English for either 'have' or 'have not'-- it is impossible to judge. 'Ain't' normally, but still substandardly, means 'am not', as in 'I'm good in English, ain't I?'

(2) Is the correct form of (1)--except for the 'never' of course-- and means that I have never met a person with your qualities.

1. I ain't never seen anyone like you.
2. I have never seen anyone like you.
So #1 and #2 mean the same thing?

3. I haven't seen anyone like you.
What do #2 and #3 mean?

[Mister Micawber]

I have never met a person with your qualities.

as I stated above.

Thanks.

1. I have not met anyone like you.
2. I have never met anyone like you.

So 'I have not...' and 'I have never..' in this case they mean the same thing?

[Mister Micawber]

Yes. The 'never' of (2) just serves as an intensifier of the 'not' in (1).

Thanks.
