Earthquake brings desolation (10)
I believe the answer is:
heartbreak
This clue could be a double definition.
'earthquake' is the first definition.
Although both the answer and definition are singular nouns, I can't see how one could define the other.
'desolation' is the second definition.
(thesaurus)
'brings' acts as a link.
Can you help me to learn more?
(Other definitions for heartbreak that I've seen before include "Grief" , "Anguish" , "sad state" , "Intense disappointment" , "Overwhelming distress" .)
