Chip from Ohio is able to head north (5)
I believe the answer is:
nacho
'chip' is the definition.
(I've seen this before)
'ohio is able to head north' is the wordplay.
'ohio' becomes 'oh' (abbreviation).
'is able to' becomes 'can' (if you can do something you are able to do it).
'head north' says the letters should be written backwards (I've seen 'heading north' mean this (in a down clue, letters travel north)).
'oh'+'can'='ohcan'
'ohcan' backwards is 'NACHO'.
'from' is the link.
(Other definitions for nacho that I've seen before include "Piece of tortilla served with sauce" , "chip production line unit" , "Something consumed" , "Mexican tortilla chip" , "Tortilla chip topped with cheese and spices" .)
