From part of England, say, needing to go back or go west (7)
I believe the answer is:
geordie
'go west' is the definition.
The definition suggests a singular noun which matches the answer.
'from part of england say needing to go back' is the wordplay.
I cannot quite see how this works, but
'of' could be 'o' and 'o' is located in the answer.
'england' could be 'e' and 'e' is located in the answer.
'go' could be 'die' ('die' can be a synonym of 'go') and 'die' is found in the answer.
This explanation may well be incorrect...
'or' acts as a link.
Can you help me to learn more?
(Other definitions for geordie that I've seen before include "North-easterner" , "Tynesider" , "Native of Newcastle" , "Native of Tyneside" , "Newcastle-born?" .)
