Beastly medic? (3)
I believe the answer is:
vet
'beastly medic?' is the definition.
The answer and definition can be both people as well as being singular nouns.
Maybe they are linked in a way I don't understand?
This is all the clue.
Can you help me to learn more?
(Other definitions for vet that I've seen before include "Examine carefully for suitability" , "Ex-serviceman" , "Scrutinise" , "A diminutive animal doctor" , "Animal doctor, in brief" .)
