The sailors' song (6)
I believe the answer is:
shanty
'the sailors' song' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for shanty that I've seen before include "folk song" , "A traditional sailors' ballad" , "Slum ghetto" , "Ramshackle dwelling" , "A song for sailors or a ramshackle house" .)
