Revived, cuckoo raced up tree (11)
I believe the answer is:
recuperated
'revived' is the definition.
The definition and answer can be both related to bodily activities as well as being past participle verbs.
Maybe you can see an association between them that I don't see?
'cuckoo raced up tree' is the wordplay.
'cuckoo' is an anagram indicator (I've seen this in other clues).
'raced'+'up'+'tree'='raceduptree'
'raceduptree' is an anagram of 'RECUPERATED'.
Can you help me to learn more?
(Other definitions for recuperated that I've seen before include "Recovered" , "Regained health" .)
