Revolutionary fuel Biden reserves for consumption (6)
I believe the answer is:
'revolutionary' is the definition.
Both the definition and answer are adjectives. Maybe there's an association between them I don't understand?
'fuel biden reserves for consumption' is the wordplay.
'EDIBLE' is hidden backwards within the letters.
However, I'm uncertain how this is indicated.
Can you help me to learn more?
(Other definitions for edible that I've seen before include "Fit to be consumed" , "Suitable for use as food" , "One's fare should be" , "Fit for eating" , "can be taken in" .)
