Subtle meaning confused one voter (8)
I believe the answer is:
overtone
'subtle meaning' is the definition.
'overtone' can be an answer for 'meaning' (overtone is a kind of meaning). I'm unsure of the 'subtle' bit.
'confused one voter' is the wordplay.
'confused' is an anagram indicator.
'one'+'voter'='onevoter'
'onevoter' with letters rearranged gives 'OVERTONE'.
Can you help me to learn more?
(Other definitions for overtone that I've seen before include "hidden meaning" , "Subtle quality" , "part of harmonic series" , "Subtle implication or connotation" , "Association" .)
