Sailor in journey coming to northern country (5)
I believe the answer is:
gabon
'country' is the definition.
(Gabon is an example)
'sailor in journey coming to northern' is the wordplay.
'sailor' becomes 'ab' (abbreviation for able seaman).
'in' means one lot of letters goes inside another.
'journey' becomes 'go' (I've seen this in other clues**).
'coming to' means one lot of letters go next to another.
'northern' becomes 'n' (abbreviation e.g. N. Ireland).
'ab' inserted inside 'go' is 'gabo'.
'gabo'+'n'='GABON'
(Other definitions for gabon that I've seen before include "French spoken here" , "W. African republic" , "African country, capital Libreville" , "state of Africa" , "Republic on the west coast of Africa" .)
