Anybody mighty stops handle turning (8)
I believe the answer is:
everyman
'anybody' is the definition.
(I've seen this before)
'mighty stops handle turning' is the wordplay.
'mighty' becomes 'very' (synonyms).
'stops' indicates putting letters inside.
'handle' becomes 'name' (handle can mean a name or nickname).
'turning' says the letters should be written backwards.
'name' written backwards gives 'eman'.
'very' inserted inside 'eman' is 'EVERYMAN'.
(Other definitions for everyman that I've seen before include "Average Joe" , "Mystery play character" , "Mr Average" , "Old morality play" , "A typical human being" .)
