How can you make a feast merely on a bone? (5)
I believe the answer is:
beano
'how can' is the definition.
Although both the answer and definition are singular nouns, I don't see how one could define the other.
'you make a feast merely on a bone?' is the wordplay.
'a bone' anagrams to 'BEANO'.
However, I am unsure how the anagram is indicated.
Can you help me to learn more?
(Other definitions for beano that I've seen before include "Junket - children's comic" , "Kids' comic" , "Rowdy jollification" , "Enjoyable party" , "Informal party" .)
