A sailor with taste (4)
I believe the answer is:
salt
I believe this is a double definition.
'a sailor' is the first definition.
(salt is a kind of sailor)
'taste' is the second definition.
(I know that salt is a type of taste)
'with' is the link.
(Other definitions for salt that I've seen before include "Mariner; sodium chloride" , "Wit; sodium chloride" , "Seasoning; old sailor" , "Pile up" , "Crystalline substance used to season food" .)
