Sound of Queen always with live value (11)
I believe the answer is:
reverberate
'sound' is the definition.
(I know that reverberate is a type of sound)
'queen always with live value' is the wordplay.
'queen' becomes 'r' (abbreviation for regina, e.g. in ER ).
'always' becomes 'ever' (synonyms).
'with' means one lot of letters go next to another.
'live' becomes 'be' (synonyms).
'value' becomes 'rate' (both can mean to esteem).
'r'+'ever'+'be'+'rate'='REVERBERATE'
'of' acts as a link.
(Other definitions for reverberate that I've seen before include "boom" , "Resound" , "ring" , "Echo around" , "Echo loudly" .)
