Cod Beth cooked is badly done (7)
I believe the answer is:
botched
'badly done' is the definition.
The definition and answer can be both to do with social activities as well as being past participle verbs.
Perhaps you can see an association between them that I don't see?
'cod beth cooked' is the wordplay.
'cooked' is an anagram indicator (letters cooked into a new form).
'cod'+'beth'='codbeth'
'codbeth' with letters rearranged gives 'BOTCHED'.
'is' is the link.
Can you help me to learn more?
(Other definitions for botched that I've seen before include "Messed up" , "Made a mess of, spoiled by clumsy work" , "Made a bags of" .)
