Ban plaster cast in West Country town (10)
I believe the answer is:
barnstaple
'west country town' is the definition.
'barnstaple' can be an answer for 'town' (I've seen this before). I'm unsure of the 'west country' bit.
'ban plaster cast' is the wordplay.
'cast' indicates anagramming the letters (letters are dispersed or cast around).
'ban'+'plaster'='banplaster'
'banplaster' with letters rearranged gives 'BARNSTAPLE'.
'in' is the link.
Can you help me to learn more?
(Other definitions for barnstaple that I've seen before include "Devon location" , "Town of North Devon" .)
