One drunkard turns to espy another (7)
I believe the answer is:
tosspot
'one drunkard turns to espy another' is the definition.
I can't tell whether this defines the answer.
'one drunkard turns to espy' is the wordplay.
'one drunkard' becomes 'sot' (sot can mean a drunken person).
'turns' says the letters should be written in reverse.
'to espy' becomes 'spot' ('spot' can be a synonym of 'espy').
'sot' back-to-front is 'tos'.
'tos'+'spot'='TOSSPOT'
Can you help me to learn more?
(Other definitions for tosspot that I've seen before include "One drinker" , "One drunkard" , "Drunk (informal)" , "Habitual drinker" , "Fool" .)
