Extra styles with additional meanings (9)
I believe the answer is:
overtones
'additional meanings' is the definition.
'overtones' can be an answer for 'meanings' (overtone is a kind of meaning). I am not sure about the 'additional' bit.
'extra styles' is the wordplay.
'extra' becomes 'over' (both can mean left over).
'styles' becomes 'tones' (tone is a kind of style).
'over'+'tones'='OVERTONES'
'with' acts as a link.
Can you help me to learn more?
(Other definitions for overtones that I've seen before include "Subtle implications" , "added nuances" , "subtle innuendoes" , "Upper partials" .)
