[Grammar] it or one?

[ayumicat]

What is the different between it or one?
Take this as example.
A:I left my cellphone at home. Could I borrow yours?
B:I don't have _one___. Maybe you can use the public phone over there.
Can I relpace "it" with "one" in that slot?
If we can't do this, what's the reason?
Thanks a lot.

I don't have one = I do not own a cell phone so I can't lend you one.
I don't have it [with me] = I own a cell phone but I am not carrying it at the moment so I can't lend it to you.

"One" refers to a cell phone of any kind.
"It" refers specifically to my cell phone.

Thank you so much.
But someone (I am not sure if he or she is a native speaker) said the sentence I don't have it without "with me" is wrong. Is it true?
My friend, a native speaker, said both the sentences I don't have it and I don't have one are correct, but they have different meanings. His explanation is like yours.

Hello.

I don't think that emsr2d2 could give you a wrong sentence.
As you can see from the post #2 they have different meanings and "I don't have it with me" is possible.

Boris.

I think emsr2d2 and my native-speaking friend are right. I want to know if the person who said "I don't have it" is incorrect without with me is wrong. Since the person may be a non-native speaker, I doubt his or her answer. Is it a MUST to put with me after have it? Thanks.

When you say "I don't have it", you do not have to say "…with me" as well.

a) Can I borrow your cell phone?
b) I don't have it. I left it in the car.

Q: Can I borrow your cell phone?
A: Sorry, I haven't got it. I left it at home.
or
A: Sorry, I haven't got it with me. I left it in the car.

Q: Can I borrow a cell phone?
A: Sorry, I haven't got mine. I left it at home.
or
A: Sorry, I haven't got mine with me. I left it at the pub.

Q: Can I borrow a cell phone?
A: Sorry, I don't have one. I think they're a waste of money.

It is not necessary to say "with me", but it does add the information that the speaker owns a cell phone but it is not in their possession at the time of speaking. That makes no difference, of course, to the outcome of that particular conversation - they still can't lend the phone to anyone.

Note that in BrE, we say "I haven't got" as well as "I don't have".
