In Greater Manchester, a funny place for Alps (5)
I believe the answer is:
wigan
'funny place for alps' is the definition.
I can't judge whether this defines the answer.
'in greater manchester a' is the wordplay.
'in greater manchester' becomes 'wig' (I can't justify this - if you can you should believe this answer much more).
'a' becomes 'an'.
'wig'+'an'='WIGAN'
Can you help me to learn more?
(Other definitions for wigan that I've seen before include "The Road to -- Pier (Orwell)" , "Manchester-area town, its Pier, Orwell" , "Lancashire town" , "Lancashire FC" , "North-western town" .)
