Monkey doctor holding limb firm (8)
I believe the answer is:
marmoset
This clue could be a double definition.
'monkey' is the first definition.
(I know that marmoset is a type of New World monkey)
'doctor holding limb firm' is the second definition.
Although both the answer and definition are singular nouns, I don't understand how they can define each other.
Can you help me to learn more?
(Other definitions for marmoset that I've seen before include "Small monkey - Rome's mat (anag)" , "Small tropical American monkey" , "Small bushy-tailed monkey" , "Star memo about kind of monkey" , "Turn morse mat over for the monkey" .)
