Might one be upset in red with Villa up? (12)
I believe the answer is:
liverpudlian
'might one' is the definition.
Although both the answer and definition are adjectives, I can't understand how one could define the other.
'upset in red with villa up?' is the wordplay.
'upset' indicates an anagram.
'with' is a charade indicator (letters next to each other).
'in'+'red'+'villa'+'up'='inredvillaup'
'inredvillaup' anagrammed gives 'LIVERPUDLIAN'.
'be' is the link.
Can you help me to learn more?
(Other definitions for liverpudlian that I've seen before include "Scouser" , "Northerner" , "Black, say" , "Harrison, say" , "Scouse" .)
