It's high and to the right (3)

I believe the answer is:

tor

I'm a little stuck... Click here to teach me more about this clue!

'it's high' is the definition.
I can't tell whether this defines the answer.

'to the right' is the wordplay.
'the right' becomes 'r' (abbreviation).
'to'+'r'='TOR'

'and' is the link.

Can you help me to learn more?

(Other definitions for tor that I've seen before include "Dartmoor peak" , "Rot on a hill in Cornwall" , "fell" , "feature of Glastonbury" , "Rot on rocky peak" .)

I've seen this clue in the Evening Standard.
