Town to prohibit travel before end of war (6)
I believe the answer is:
bangor
'town' is the definition.
Both the definition and answer are singular nouns.
Perhaps you can see a link between them that I can't see?
'prohibit travel before end of war' is the wordplay.
'prohibit' becomes 'ban' (banning is a kind of prohibiting).
'travel' becomes 'go' (synonyms).
'before' says to put letters next to each other.
'end of' indicates one should take the final letters.
The final letter of 'war' is 'r'.
'ban'+'go'+'r'='BANGOR'
'to' is the link.
(Other definitions for bangor that I've seen before include "Town in Wales and in Northern Ireland" , "University city on the Menai Strait" , "Town in NI and Wales" , "North Wales university" , "N. Wales, N. Ireland, towns" .)
