Quiet lift gets approval (6)
I believe the answer is:
praise
'approval' is the definition.
(praise is a kind of approval)
'quiet lift' is the wordplay.
'quiet' becomes 'p' (music symbol for 'piano').
'lift' becomes 'raise' ('raise' can be a synonym of 'lift').
'p'+'raise'='PRAISE'
'gets' is the link.
(Other definitions for praise that I've seen before include "Aspire (anag)" , "Express approval and admiration" , "Speak highly of" , "Commendation" , "Congratulate" .)
