Sailors possibly in a shipwreck (4)
I believe the answer is:
crew
'sailors' is the definition.
(I've seen this before)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for crew that I've seen before include "boastful" , "A kind of short cut" , "Those who man a ship or aircraft" , "Ship's or aircraft's staff" , "Ship's men" .)
