Round bird? (5)
I believe the answer is:
robin
This might be a double definition.
'round' is the first definition.
Although both the answer and definition are singular nouns, I don't understand how they can define each other.
'bird?' is the second definition.
(I know that robin is a type of oscine)
Can you help me to learn more?
(Other definitions for robin that I've seen before include "Hood, possibly" , "Bird, killed by Sparrow" , "Batman's assistant" , "So-called outlaw" , "Small brown and red bird" .)
