Tail removed from genuine old parrot (4)
I believe the answer is:
echo
'parrot' is the definition.
(thesaurus)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for echo that I've seen before include "Reiterate" , "Ape" , "Be suggestive of" , "repetitive" , "A natural sound reflection" .)
