Many an auricle is not clogged up with wax (5)
I believe the answer is:
clear
'not clogged up with wax' is the definition.
I can't judge whether this definition defines the answer.
'many an auricle' is the wordplay.
'many an' becomes 'cl' (I am not sure about this - if you are sure you should believe this answer much more).
'auricle' becomes 'ear' (synonyms).
'cl'+'ear'='CLEAR'
'is' is the link.
Can you help me to learn more?
(Other definitions for clear that I've seen before include "Open; not cloudy" , "Free from blame" , "Discharge (debt), unclouded" , "negotiate" , "Patent" .)
