"what time" or "at what time"?

[massimoparente]

Hello,

which of the two following question is the correct one?

What time are you leaving?
At what time are you leaving?

I don't understand the difference between "what" and "at what".

Can you help me?


Thanks,
Massimo

They're the same. The difference, at is omitted in [1]:

[1] What time are you leaving (at)?
[2] At what time are you leaving?

There's a Latin rule borrowed into English that states, one should never end a sentence with a preposition. The result, some speakers move the preposition to the front of the clause ([2]), other speakers omit (1), and yet other speakers just leave it where it is. The result, three ways to say the same thing:

Statement: I am leaving at 4 p.m.

Questions:
What time are you leaving at?
At what time are you leaving?
What time are you leaving?

Does that help?

Massimo, you're most welcome.

Is it correct for any sentences or is it just a collocation?

What are you looking for?
Can I omit for here? But it is a phrasal verb.

Phrasal verbs are different.

Ex: What are you looking for?
Ex: For what are you looking?
Ex: What are you looking?
