The blue area on the weather map? (10)
I believe the answer is:
depression
This could be a double definition.
'the blue area' is the first definition.
The definition and answer can be both states of affairs as well as being singular nouns.
Maybe you can see an association between them that I don't see?
'the weather map?' is the second definition.
The definition and answer can be both relationships as well as being singular nouns.
Maybe you can see an association between them that I can't see?
'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" .)
