Island surroundings (3)
I believe the answer is:
sea
This could be a double definition.
'island' is the first definition.
The answer and definition can be both natural objects as well as being singular nouns.
Perhaps you can see an association between them that I don't see?
'surroundings' 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 sea that I've seen before include "Division of an ocean" , "North for one" , "Marine" , "The Aegean, for example" , "The drink" .)
