Shattering discovery in Moab tomb (4,4)
I believe the answer is:
atom bomb
'shattering discovery' is the definition.
Although both the answer and definition are singular nouns, I cannot see how one could define the other.
'moab tomb' is the wordplay.
'moab tomb' anagrams to 'ATOM BOMB'.
But, I am not clear how the anagram is indicated.
'in' is the link.
Can you help me to learn more?
(Other definitions for atom bomb that I've seen before include "Destructive weapon" , "Weapon of mass destruction" , "Big weapon" , "The first one fell on Hiroshima" , "Explosive causing huge cloud" .)
