Explosive device briefly associated with a Caribbean state (7)
I believe the answer is:
grenada
'caribbean state' is the definition.
(country in the Caribbean)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for grenada that I've seen before include "Island state in the West Indies" , "West Indian island" , "A garden (anag) - Caribbean island" , "Caribbean island country" , "Nation" .)
