Will he not have a drink while tattooing the sailor? (9)
I believe the answer is:
abstainer
'will he not have a drink while tattooing the sailor?' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
'will he not have' is the wordplay.
'will' is a charade indicator (letters next to each other) (I've seen this in other clues).
'he' becomes 'Ab'.
'not have' becomes 'stainer' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'ab' next to 'stainer' is 'ABSTAINER'.
Can you help me to learn more?
(Other definitions for abstainer that I've seen before include "AA member" , "One declining to vote" , "One refusing hard stuff" , "Bull's not my stuff" , "one on the wagon" .)
