Describes town on the outskirts of Ulster, bringing in prohibition (5)
I believe the answer is:
urban
'describes town on' is the definition.
I can't tell whether this definition defines the answer.
'outskirts of ulster bringing in prohibition' is the wordplay.
'outskirts of' means to remove the middle letters (only letters on the outskirts).
'bringing' says to put letters next to each other.
'in prohibition' becomes 'ban' (I am not sure about this - if you are sure you should believe this answer much more).
'ulster' with its centre removed is 'ur'.
'ur'+'ban'='URBAN'
'the' is the link.
Can you help me to learn more?
(Other definitions for urban that I've seen before include "Name adopted by eight popes: built-up" , "Civic" , "Relating to town/city" , "Of or about city areas" , "Of towns or cities" .)
