I have a doubt

what = the thing that

eg i don't know what you are talking about ?

= I don't know the thing that you are talking about ?


I bought a book which cost $20.

which = book

"What" is one of the most over-used words in the English language. It can be a pronoun; it can be a determiner; it can stand for "that which"; it can be either reflexive or interrogative; it ask a question; it can supply an answer. It can even (as a recent thread revealed) stand for "what kind of".

"Which" has similar properties, but isn't quite so overused.

In general

There is no difference in actual meaning between "What time is it?" and "What is the time?".

To ride (in a vehicle) is to be a passenger;
To drive (a vehicle) is to be the driver.

Both words have many other meanings also.

But you couldn't say, "Can you ride me?", could you?

I might if I wanted ***, but not otherwise.

I think what you need to say is "Would you give me a lift?". Idiomatic though it may be, that's how you request for someone to drive you somewhere in a vehicle.

Thank you very much!!!

Hi Rommie,

Can I say "Would you give me a ride?" instead?

Yup, no probs.
