Pole going to the West Indies to find success (3)
I believe the answer is:
win
'success' is the definition.
(I know that success can be written as win)
'pole going to the west indies' is the wordplay.
'pole' becomes 'n' (abbreviation for North, as in North Pole).
'going to' says to put letters next to each other.
'the west indies' becomes 'wi'.
'n' put after 'wi' is 'WIN'.
'to find' acts as a link.
(Other definitions for win that I've seen before include "Be successful" , "Achieve victory" , "Gain; triumph" , "Come first" , "Finish in first place" .)
