Overseas sailor’s on the street (6)
I believe the answer is:
abroad
'overseas' is the definition.
(synonyms)
'sailor's on the street' is the wordplay.
'sailor' becomes 'ab' (abbreviation for able seaman).
'on' is a charade indicator (letters next to each other).
'the street' becomes 'road' (I've seen this before).
'ab'+'road'='ABROAD'
(Other definitions for abroad that I've seen before include "Pole would be so" , "out of UK?" , "At large; widely current" , "At large - overseas" , "Stare lecherously at (someone)" .)
