Strange in spirit? (3)
I believe the answer is:
rum
This clue is a double definition.
'strange' is the first definition.
(synonyms)
'spirit?' is the second definition.
(alcoholic spirit)
'in' acts as a link.
(Other definitions for rum that I've seen before include "Odd like drink distilled from molasses" , "Alcoholic drink from molasses" , "The spirit is peculiar" , "Strange drink from molasses" , "Weird" .)
