For some seafarers, it's a long way to go (4)
I believe the answer is:
afar
'a long way to go' is the definition.
I can't tell whether this defines the answer.
'for some seafarers' is the wordplay.
'AFAR' is hidden in amongst the letters.
But, I am not sure how this is indicated.
'it's' acts as a link.
Can you help me to learn more?
(Other definitions for afar that I've seen before include "Inhabitant of Ethiopia" , "Unusually distant" , "a good way off" , "A long way away" , "(From/at) a great distance" .)
