Prepared to explode - or not to explode (5)
I believe the answer is:
fused
'prepared' is the definition.
Both the definition and answer are adjectives. Perhaps there's a link between them I don't understand?
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for fused that I've seen before include "Married" , "Joined by melting" , "Combined" , "Welded together by heat" , "Coalesced" .)
