Twisted Byzantine tragedy (7)
I believe the answer is:
gyrated
'twisted' is the definition.
The answer and definition can be both to do with motion as well as being past participle verbs.
Perhaps there's an association between them I don't understand?
'byzantine tragedy' is the wordplay.
'byzantine' is an anagram indicator (byzantine means complex or confusing).
'tragedy' with letters rearranged gives 'GYRATED'.
Can you help me to learn more?
(Other definitions for gyrated that I've seen before include "did turns" , "What Turner did" , "Writhed" , "What whirling dervishes did" .)
