Feast made of a bone? (5)
I believe the answer is:
beano
'feast' is the definition.
(I've seen this before)
'of a bone?' is the wordplay.
'of' indicates an anagram (the answer comes from or \'of\' the letters).
'a'+'bone'='abone'
'abone' anagrammed gives 'BEANO'.
'made' acts as a link.
(Other definitions for beano that I've seen before include "Celebration" , "Kids' comic" , "binge" , "Rowdy jollification" , "Function" .)
