He often lifts his glass to each (5)
I believe the answer is:
toper
'he often lifts his glass' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
'to each' is the wordplay.
'each' becomes 'per'.
'to'+'per'='TOPER'
Can you help me to learn more?
(Other definitions for toper that I've seen before include "Regular drinker" , "Drunkard" , "Drinker, imbiber" , "Trope for habitual drinker" , "Wino" .)
