Angry man not taking booze inside (5)
I believe the answer is:
ratty
'angry' is the definition.
(thesaurus)
'man not taking booze inside' is the wordplay.
'man' becomes 'r' (abbreviation for rook, a chess piece or 'man').
'not taking booze inside' becomes 'atty' (I can't explain this - if you can you should believe this answer much more).
'r'+'atty'='RATTY'
Can you help me to learn more?
(Other definitions for ratty that I've seen before include "Fictional mole's chum" , "character on the river bank" , "Moley's friend" , "Bad tempered" , "infestation of vermin" .)
