Parrot's speech offensive to some extent (4)

I believe the answer is:

echo

'parrot's' is the definition.
(thesaurus)

'speech offensive to some extent' is the wordplay.
'to some extent' indicates the answer is hidden within the clue.
'ECHO' is hidden in the letters of 'speech offensive'.

(Other definitions for echo that I've seen before include "What evokes memories" , "Before foxtrot" , "The distant sound" , "repeated answer" , "Sound following" .)

I've seen this clue in The Telegraph.
