What stops boozer going back? (5)
I believe the answer is:
rehab
'what stops boozer going back?' is the definition.
I know nothing about this answer so I cannot judge whether it can be defined by this definition.
'what stops boozer going back?' is the wordplay.
'what' becomes 'eh' (sound used to ask 'what?' or 'pardon?').
'stops' is an insertion indicator (stopping can mean blocking a gap).
'boozer' becomes 'bar'.
'going back?' says the letters should be written backwards.
'bar' written backwards gives 'rab'.
'eh' put inside 'rab' is 'REHAB'.
Can you help me to learn more?
(Other definitions for rehab that I've seen before include "brief convalescence?" , "Treatment for alcohol or drug dependence" , "Treatment for, eg, addiction" , "Treatment for alcohol abuse" , "Treatment for alcoholism" .)
