Openers for Caribbean islands (4)
I believe the answer is:
keys
This might be a double definition.
'openers' is the first definition.
(I've seen this in another clue)
'islands' is the second definition.
(I know this)
'for caribbean' acts as a link.
I am not very happy about this link. Some or all of it may belong to one of the definitions.
Can you help me to learn more?
(Other definitions for keys that I've seen before include "Low-lying Caribbean islands" , "Musical scales" , "'Unlockers'" , "Lock-openers?" , "Lower House of the Isle of Man parliament" .)
