Man from borders in England to be a success (5)
I believe the answer is:
edwin
'man from borders' is the definition.
'edwin' can be an answer for 'man' (I've seen this before). I'm not sure about the 'from borders' bit.
'england to be a success' is the wordplay.
'england' becomes 'E' (short for England).
'to be a' becomes 'd' (I am not sure about this - if you are sure you should believe this answer much more).
'success' becomes 'win' (I've seen this in another clue).
'e'+'d'+'win'='EDWIN'
'in' is the link.
Can you help me to learn more?
(Other definitions for edwin that I've seen before include "-- Hubble (astronomer)" , "Northumbrian king" , "Man" , "Wined (anag.), man's name" , "Dickens novel 'The Mystery of . . . . . Drood'" .)
