At the corner vs. On the corner and etc.

[Penny Lane]

Which is correct?

At the corner
On the corner

Or,, does it differ depending on the sentences?

wonder about

Around the corner
Round the corner

as well.

or do they all have different meaning?

Cheers :P

For directions you say:

The cafe is on the corner of this street and that street.
Turn left at the corner of---rd and--rd.

For position of something:

A vase stood in the corner of the room.

The shop is around the corner.
'round is just a shortened version of around and used in spoken form, not in written form. English speakers sometimes swallow endings and beginnings of words when speaking fast - sorry!

Brilliant!
It's a perfect answer. Cheers Becker : )
Yeah, I also though, British use round a lot. 'you wanna come round?' 'round the corner' and stuff.
Anyway you don't need to be sorry :P
Cheers again.
