Damn the explosion (5)
I believe the answer is:
blast
I believe this is a double definition.
'damn' is the first definition.
(thesaurus)
'the explosion' is the second definition.
(blast is a kind of explosion)
(Other definitions for blast that I've seen before include "Great time: explosion" , "Blow up with explosives" , "Strong gust of air" , "Sudden, strong current of air" , "Severely criticise" .)
