Excellent tippler, on reflection (7)
I believe the answer is:
tosspot
'excellent tippler on reflection' is the definition.
I can't tell whether this definition defines the answer.
'excellent tippler on reflection' is the wordplay.
'excellent' becomes 'tops' (I've seen this before).
'tippler' becomes 'sot' (I've seen this in another clue).
'on reflection' shows that the letters should be reversed in order.
'tops'+'sot'='topssot'
'topssot' in reverse letter order is 'TOSSPOT'.
Can you help me to learn more?
(Other definitions for tosspot that I've seen before include "One drunkard" , "Habitual drinker" , "supper, habitually" , "Drunk (informal)" , "Fool" .)
