Quietly mentions compliments (7)
I believe the answer is:
praises
'compliments' is the definition.
(I've seen this in another clue)
'quietly mentions' is the wordplay.
'quietly' becomes 'p' (p for piano and quiet).
'mentions' becomes 'raises' (raising is a kind of mentioning).
'p'+'raises'='PRAISES'
(Other definitions for praises that I've seen before include "Commends, hails" , "Worships" , "Extols, lauds" .)
