Find sea eagle in another nest (4)
I believe the answer is:
erne
'find sea eagle' is the definition.
Although both the answer and definition are singular nouns, I cannot understand how they can define each other.
'in another nest' is the wordplay.
'in' indicates a hidden word.
'ERNE' can be found hidden inside 'another nest'.
Can you help me to learn more?
(Other definitions for erne that I've seen before include "Sea bird: lough in Ulster" , "River and lake of the North" , "White-tailed eagle" , "Lough of the North" , "European sea eagle" .)
