Does coping with dirty habits make him thirsty? (3,7)
I believe the answer is:
dry cleaner
'does coping with dirty habits make him' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
'thirsty?' is the wordplay.
I cannot really understand how this works, but
'thirsty?' could be 'dry' ('dry' can be similar in meaning to 'thirsty') and 'dry' is found within the answer.
The remaining letters 'cleaner' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for dry cleaner that I've seen before include "Hero of The Three Musketeers" , "Clothes refresher" , "Who could improve habits" .)
