Parody, almost unbiased, into chaos (13)
I believe the answer is:
impersonation
'parody' is the definition.
(thesaurus)
'almost unbiased into chaos' is the wordplay.
I cannot really understand how this works, but
an anagram of 'into' is 'tion' which is within the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for impersonation that I've seen before include "Pretence of being someone else" , "Mimicry" , "Act of pretending to be another" , "identity theft?" , "Pretending to be someone else" .)
