Most of the taxmen... they leave the man dry (7)
I believe the answer is:
thirsty
'dry' is the definition.
(similar in meaning)
'most of the taxmen they leave the man' is the wordplay.
'most of' means to remove the last letter.
'taxmen' becomes 'ir' (I've seen this in other clues).
'they leave' becomes 's' (I am not sure about this - if you are sure you should believe this answer much more).
'the man' becomes 'Ty'.
'the' with its final letter taken away is 'th'.
'th'+'ir'+'s'+'ty'='THIRSTY'
Can you help me to learn more?
(Other definitions for thirsty that I've seen before include "Gasping" , "Parched" , "Needing a drink" , "Feeling the need to drink" , "Keen" .)
