[Grammar] What do you need help/ need to help with?

[wotcha]

1. What do you need help with?

2. What do you need to help with?

3. What need you help with?


Are these sentences all grammatical and same in meaning?

 

[5jj]

Only the first is both natural and correct. The second is possible in some contexts, though people don't normally 'need' to help with things. The third is wrong.

 

[bhaisahab]

Even if #2 were natural, it wouldn't have the same meaning as #1.
