Regarding what you say, is not one of the listeners
'of the listeners' is the definition.
The definition suggests a singular noun which matches the answer.
'regarding what you say is not one' is the wordplay.
I cannot quite understand how this works, but
'regarding' could be 're' ('re' means regarding or about) and 're' is found in the answer.
'one' could be 'i' (Roman numeral) and 'i' is located in the answer.
This explanation may well be incorrect...
