Strange Caribbean spirit (3)
I believe the answer is:
rum
This clue could be a double definition.
'strange' is the first definition.
(synonyms)
'caribbean spirit' is the second definition.
'rum' can be an answer for 'spirit' (alcoholic spirit). I'm not certain of the 'caribbean' bit.
Can you help me to learn more?
(Other definitions for rum that I've seen before include "Odd sort of spirit used in grog" , "Sugar-cane spirit" , "Odd sort of drink" , "Queer" , "Odd kind of drink for sailor" .)
