With Rex, close to George Galloway's home? (4)
I believe the answer is:
byre
'galloway's home?' is the definition.
The definition suggests a singular noun which matches the answer.
'with rex close to george' is the wordplay.
'with' becomes 'by' (both can mean close together).
'rex' becomes 'r' (abbreviation e.g. GR=George Rex, King George).
'close to' suggests the final letters (the close of something is the end).
The final letter of 'george' is 'e'.
'by'+'r'+'e'='BYRE'
Can you help me to learn more?
(Other definitions for byre that I've seen before include "Cattle-shed" , "Cow shelter" , "Durham's cover" , "lower in here" , "Cowhouse" .)
