Beastly food for a chap with a broken leg (6)
I believe the answer is:
mangel
'beastly food' is the definition.
I know nothing about this answer so I cannot judge whether it can be defined by this definition.
'chap with a broken leg' is the wordplay.
'chap' becomes 'man' (chap can mean a man).
'with' is a charade indicator (letters next to each other).
'a broken' indicates anagramming the letters.
'leg' with letters rearranged gives 'gel'.
'man'+'gel'='MANGEL'
'for a' is the link.
Can you help me to learn more?
(Other definitions for mangel that I've seen before include "Type of beet for cattle fodder" , "cattle food" .)
