Made a mockery of the men (5)
I believe the answer is:
guyed
'made' is the definition.
The definition and answer can be both related to change as well as being past participle verbs.
Perhaps there's a link between them I don't understand?
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for guyed that I've seen before include "Secured with rope" , "sent up" , "Made fun of - kept in position by ropes" .)
