Bond trained parrot to keep quiet (7)
I believe the answer is:
rapport
'bond' is the definition.
(I've seen this before)
'trained parrot to keep quiet' is the wordplay.
'trained' indicates anagramming the letters (to train can mean to grow something into a shape).
'to keep' means one lot of letters goes inside another.
'quiet' becomes 'p' (music symbol for 'piano', ie soft or quiet).
'parrot' anagrammed gives 'raport'.
'raport' enclosing 'p' is 'RAPPORT'.
(Other definitions for rapport that I've seen before include "Relation, connection" , "Harmonious and understanding relationship between people" , "Mutual harmony and affinity" , "Empathy" , "Bond of sympathy" .)
