Strange nodule flummoxed canine specialist (6,7)
I believe the answer is:
dental surgeon
'canine specialist' is the definition.
The answer and definition can be both people as well as being singular nouns.
Maybe there's an association between them I don't understand?
'strange nodule flummoxed' is the wordplay.
'strange nodule' can be anagrammed to 'DENTAL SURGEON'.
However, I'm not sure how this is indicated.
Can you help me to learn more?
(Other definitions for dental surgeon that I've seen before include "Medic having to fill in" , "Canine expert" , "Gnashers' doctor" , "Expert on 10 across cavities?" , "One treating teeth" .)
