Make a feast of a bone (5)
I believe the answer is:
beano
'make a feast' is the definition.
The definition and answer can be both acts as well as being singular nouns.
Perhaps there's an association between them I don't understand?
'of a bone' is the wordplay.
'of' is an anagram indicator (the answer comes from or \'of\' the letters).
'a'+'bone'='abone'
'abone' anagrammed gives 'BEANO'.
Can you help me to learn more?
(Other definitions for beano that I've seen before include "Junket - children's comic" , "Comic and informal get-together" , "Comic - party" , "Celebration" , "Informal party" .)
