Need as a modal verb and need as a function verb

[alandro255]

It's very difficult for me to distinguish the "need" modal with the "need" ordinary verb in American English and in British in English in the sentences as follows:

1/ I don't need to go to class.
= I needn't to go to class ?
2/ I didn't need to go to class.
= I needn't have gone to class. ?
3/ Did you need to paid so much?
= Need you have paid so much? ?
4/ I need that book. (modal)
= I need that book. (ordinary verb) ?
5/ Do you need any help?
=Need you any help? ?
6/ She only needs to ask. (ordinary verb)
= She needs only to ask. (ordinary verb)
= She need only ask. (modal)
= She only need ask. (modal) ?
7/ Don't have to = don't need ?
Don't have to = needn't ?
Have to = need ?
Must = need ?
Mustn't = don't need ?
Mustn't = needn't ?

Please help me.
Thanks

Hi,

You say you find it very difficult to use the verb need. Where do all your examples come from?

I wrote them but I don't know when I should use as modal, when I should use as ordinary verb?

As I see it, the main difference between British and American usage is with the modal form of need: American English does not use needn't: for negative and interrogative forms we use do/does/did with need (simple present/past). I have noted everything that would be natural in American English. Where I wrote "NO", it's just plain wrong:

Hello everybody!

Just one question about the first sentence.

I needn?t to go to class.

Isn?t 'needn?t' a modal verb?

Shouldn?t it be 'I needn?t go to class'?

Thanks a lot!

Hi Jesus

Yes, you're right. That's an error, too.

That means "I don't need to go to class" and "I needn't go to class" are correct and have the same meaning. Right? (I ask it because you don't tell me your opinion about "I needn't go to class").

b/

The same,"Did you need to pay so much? " and "Need you have paid so much?" are correct and have the same meaning. Right? (I ask it because you don't tell me your opinion about "I needn't go to class").

2/ Don't have to = needn't . Right?

3/She only need ask. Right?

4/ You wrote:
Must = need (to) The meanings are sometimes the same/similar ?
What does ? mean?
