Leave comedian at hospital - unacceptable to be deprived (2,7)
I believe the answer is:
go without
'be deprived' is the definition.
I can't tell whether this definition defines the answer.
'leave comedian at hospital unacceptable' is the wordplay.
'leave' becomes 'go' (to go is to depart or leave).
'comedian' becomes 'wit' (a witty person).
'at' is a charade indicator (letters next to each other).
'hospital' becomes 'H' (abbreviation for hospital on maps).
'unacceptable' becomes 'out' (out can mean incorrect or inappropriate).
'go'+'wit'+'h'+'out'='GO WITHOUT'
'to' acts as a link.
Can you help me to learn more?
(Other definitions for go without that I've seen before include "be denied" , "Be deprived of" , "give up" , "Suffer a lack of" , "pass up" .)
