Sailors last trip (4)
I believe the answer is:
salt
'sailors last trip' is the definition.
I can't judge whether this defines the answer.
'last trip' is the wordplay.
'trip' is an anagram indicator.
'last' with letters rearranged gives 'SALT'.
Can you help me to learn more?
(Other definitions for salt that I've seen before include "Brackish" , "Crystalline substance for the table" , "Seasoning; old sailor" , "White crystalline substance" , "Condiment - experienced sailor" .)
