A bone can provide plenty to eat! (5)
I believe the answer is:
beano
'plenty to eat' is the definition.
I can't tell whether this definition defines the answer.
'a bone can' is the wordplay.
'can' indicates anagramming the letters (I've seen 'canned' mean this (canned can mean drunk)).
'a'+'bone'='abone'
'abone' anagrammed gives 'BEANO'.
'provide' is the link.
Can you help me to learn more?
(Other definitions for beano that I've seen before include "Celebration" , "Kids' comic" , "Comic - party" , "Comic and informal get-together" , "Informal party" .)
