Fierce type in endless pain seen by doctor (6)
I believe the answer is:
dragon
'fierce type' is the definition.
The definition and answer can be both people as well as being singular nouns.
Maybe there's an association between them I don't understand?
'endless pain seen by doctor' is the wordplay.
'endless pain' becomes 'agon' (I've seen this in other clues).
'seen by' is a charade indicator (letters next to each other).
'doctor' becomes 'dr' (abbreviation).
'agon' after 'dr' is 'DRAGON'.
'in' acts as a link.
Can you help me to learn more?
(Other definitions for dragon that I've seen before include "[TERMAGANT]" , "Teutonic mythological creature" , "Mythical fire-breathing creature" , "Continue interminably" , "dangerous creature?" .)
