Affects the hearing of listener from Washington? Wrong!
I believe the answer is:
earwax
'affects the hearing' is the definition.
I can't judge whether this definition defines the answer.
'listener from washington? wrong' is the wordplay.
'listener' becomes 'ear' (I've seen this before).
'from' is a charade indicator (letters next to each other).
'washington?' becomes 'wa'.
'wrong' becomes 'x'.
'ear'+'wa'+'x'='EARWAX'
'of' is the link.
Can you help me to learn more?
(Other definitions for earwax that I've seen before include "Substance accumulating in the lugholes" , "Otic deposit" , "Hearing problem" , "Otic secretion" , "Secretion in the lugholes" .)
