Bird in bank given mention (4)
I believe the answer is:
tern
This could be a double definition.
'bird' is the first definition.
(tern is a kind of bird)
'bank given mention' is the second definition.
Although both the answer and definition are singular nouns, I can't see how one could define the other.
'in' acts as a link.
Can you help me to learn more?
(Other definitions for tern that I've seen before include "Gull-like seabird" , "Fork-tailed seabird" , "Sea bird, a small gull" , "Small slender gull" , "Seabird, sounds like become sour" .)
