Mocked, having got free in action (7)
I believe the answer is:
derided
'mocked' is the definition.
(deriding is a kind of mocking)
'free in action' is the wordplay.
'free' becomes 'rid' (to be free of something is to be rid of it).
'in' is an insertion indicator.
'action' becomes 'deed' (deed is a kind of action).
'rid' inserted inside 'deed' is 'DERIDED'.
'having got' acts as a link.
(Other definitions for derided that I've seen before include "Treated or spoke of with contempt" , "Did rubbish" , "Ridiculed" , "Mocked, laughed at" , "Scorned" .)
