sir good evening,

1)what is th different between what......for & why:?:




explain difference between these sentence

1) i have knife to cut vegetable with.
2) I have knife to cut vegetable .

to cut vegetable with = to cut vegetable

 

[xpert]

As far as I'm concerned, there is no difference. Both are used to give a reason

What do you want to know for? = Why do you want to know?
What for? = why?
