Option available for the drinker (6)
I believe the answer is:
potion
'the drinker' is the definition.
Although both the answer and definition are singular nouns, I don't understand how one could define the other.
'option available' is the wordplay.
'option' can be anagrammed to 'POTION'.
Though, I am not sure how this is indicated.
'for' is the link.
Can you help me to learn more?
(Other definitions for potion that I've seen before include "bit of medicine" , "Medicinal or magical beverage" , "brew of Getafix?" , "Magic concoction" , "A liquid medicine or drug" .)
