Snake put in here sheds its skin (5)
I believe the answer is:
adder
This could be a double definition.
'snake' is the first definition.
(I know that adder is a type of viper)
'in here sheds its skin' is the second definition.
Although both the answer and definition are singular nouns, I cannot see how they can define each other.
'put' acts as a link.
Can you help me to learn more?
(Other definitions for adder that I've seen before include "accountant?" , "Small poisonous snake, viper" , "Reptilian" , "poisoner" , "danger in the countryside" .)
