Detective to manage a thousand inebriated (5)
I believe the answer is:
drunk
'inebriated' is the definition.
(I know that inebriated can be written as drunk)
'detective to manage a thousand' is the wordplay.
'detective' becomes 'd' (this might be a standard abbreviation which I don't know about).
'to manage' becomes 'run' (both can mean to organise).
'a thousand' becomes 'K' ('K' can be a synonym of 'thousand').
'd'+'run'+'k'='DRUNK'
Can you help me to learn more?
(Other definitions for drunk that I've seen before include "Toper" , "Nine Ac" , "Inebriated" , "Intoxicated" , "Wino" .)
