afar

I'm a little stuck... Click here to teach me more about this clue!

'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.

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" .)
