Drink which exceptional soprano aspires to reach? (4)
I believe the answer is:
tope
'drink' is the definition.
(I know that drink can be written as tope)
'exceptional soprano aspires to reach?' is the wordplay.
I cannot quite see how this works, but
'to' is found in the answer.
This explanation may well be incorrect...
'which' is the link.
(Other definitions for tope that I've seen before include "Small grey requiem shark" , "Drink too much like poet" , "Drink hard regularly" , "What habitual drinkers do" , "plantation?" .)
