Repeats one's rights during revolting arrest (7)
I believe the answer is:
parrots
'repeats' is the definition.
(parroting is a kind of repeating)
'one's rights during revolting arrest' is the wordplay.
'one' becomes 'a' (a thing is one thing).
'rights' becomes 'rr' (two abbreviations for right).
'during' means one lot of letters goes inside another.
'revolting' is a reversal indicator.
'arrest' becomes 'stop' (synonyms).
'stop' back-to-front is 'pots'.
'a'+'rr'='arr'
'arr' placed into 'pots' is 'PARROTS'.
(Other definitions for parrots that I've seen before include "Brightly colored tropical birds" , "Imitates" , "Brightly-coloured tropical birds" , "Repeats" , "Tropical birds able to mimic sounds" .)
