To a sailor, the way to get away from home (6)
I believe the answer is:
abroad
'away from home' is the definition.
(I've seen this in another clue)
'to a sailor the way' is the wordplay.
'to a sailor' becomes 'ab' (abbreviation for able seaman).
'the way' becomes 'road' (road is a kind of way).
'ab'+'road'='ABROAD'
'to get' acts as a link.
(Other definitions for abroad that I've seen before include "not in Britain" , "in France, say" , "Europe, for example" , "At large - overseas" , "Away from home" .)
