Strange drink for a pirate? (3)
I believe the answer is:
rum
This clue is a double definition.
'strange' is the first definition.
(similar in meaning)
'drink for a pirate?' is the second definition.
(pirates drink rum)
(Other definitions for rum that I've seen before include "The spirit is peculiar" , "An odd kind of drink made from molasses" , "Sugar-cane spirit" , "Curious, strange" , "Weird" .)
