Quiet lift gets acclaim (6)
I believe the answer is:
praise
'acclaim' is the definition.
(I've seen this before)
'quiet lift' is the wordplay.
'quiet' becomes 'p' (music symbol for 'piano', ie soft or quiet).
'lift' becomes 'raise' (synonyms).
'p'+'raise'='PRAISE'
'gets' acts as a link.
(Other definitions for praise that I've seen before include "Commend or laud" , "Be aware of (something)" , "Extol, glorify" , "plaudit" , "Worship, glorify" .)
