The blue area on the weather map? (10)
I believe the answer is:
depression
This might be a double definition.
'the blue area' is the first definition.
The answer and definition can be both states of affairs as well as being singular nouns.
Perhaps you can see a link between them that I don't see?
'the weather map?' is the second definition.
The answer and definition can be both relationships as well as being singular nouns.
Maybe there's a link between them I don't understand?
'on' is the link.
Can you help me to learn more?
(Other definitions for depression that I've seen before include "mental anguish" , "gloom" , "Pit" , "despair" , "Bad times" .)
