A place in Surrey; for instance, Ham (5)
I believe the answer is:
egham
'a place in surrey' is the definition.
I can't tell whether this definition defines the answer.
'for instance ham' is the wordplay.
'for instance' becomes 'eg' ('e.g.' can be a synonym of 'for instance').
'eg'+'ham'='EGHAM'
Can you help me to learn more?
(Other definitions for egham that I've seen before include "Somewhere in Surrey" , "Thames-side town" , "Surrey town near Runnymede" .)
