Born to come to Split (6)
I believe the answer is:
breach
'to split' is the definition.
(I've seen this before)
'born to come' is the wordplay.
'born' becomes 'b' (abbreviation next to the year of someone's birth).
'to' is a charade indicator (letters next to each other).
'come' becomes 'reach' (reaching is a kind of coming).
'b'+'reach'='BREACH'
(Other definitions for breach that I've seen before include "Opening -- infraction" , "Opening - quarrel" , "transgression" , "Gap made in a fortification" , "Violation, maybe of the peace" .)
