The result of intervention of astronomical proportions (7)
I believe the answer is:
eclipse
This could be a double definition.
'the result' is the first definition.
The answer and definition can be both related to natural events as well as being singular nouns.
Perhaps you can see an association between them that I can't see?
'intervention of astronomical proportions' is the second definition.
Although both the answer and definition are singular nouns, I don't see how one could define the other.
'of' is the link.
Can you help me to learn more?
(Other definitions for eclipse that I've seen before include "Ennui" , "dark?" , "Outdo" , "Overshadow, obscure" , "Block" .)
