Location of the fringe of Surrey (2,3)
I believe the answer is:
on top
'the fringe of surrey' is the definition.
I don't know anything about this answer so I cannot judge whether it can be defined by this definition.
'location of' is the wordplay.
I cannot really see how this works, but
'location' could be 'top' (top is a kind of location) and 'top' is found in the answer.
'of' could be 'o' and 'o' is found within the answer.
A single letter 'n' remains which might be clued in a way I don't see.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for on top that I've seen before include "In a dominant position" , "Leading" , "Winning" , "At the summit or in superior position" .)
