Hide in Greater Manchester region (4)
I believe the answer is:
bury
'hide' is the definition.
(I know that bury is a is a more specific form of the action hide)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for bury that I've seen before include "Lancs. town" , "-- St. Edmunds" , "Inter, city" , "Immerse (oneself)" , "Completely envelop" .)
