Potion originally drunk by pigeon for Alice, say? (6)
I believe the answer is:
cooper
'alice say?' is the definition.
(Alice Cooper)
'potion originally drunk by pigeon' is the wordplay.
'originally' says to take the initial letters.
'drunk by' indicates putting letters inside.
'pigeon' becomes 'cooer' (I am not sure about this - if you are sure you should believe this answer much more).
The first letter of 'potion' is 'p'.
'p' placed within 'cooer' is 'COOPER'.
'for' acts as a link.
Can you help me to learn more?
(Other definitions for cooper that I've seen before include "Porter with stout" , "Barrel-maker" , "Craftsman" , "Cask and barrel maker" , "supplier of stiffeners?" .)
