Northerner in run getting map for one day (9)
I believe the answer is:
laplander
'northerner' is the definition.
(I've seen this before)
'in run getting map for one day' is the wordplay.
'in' is an insertion indicator.
'run getting' becomes 'laer' (I can't explain this - if you can you should give a lot more credence to this answer).
'map' becomes 'plan' (I've seen this before).
'for' means one lot of letters go next to another.
'one day' becomes 'd'.
'plan'+'d'='pland'
'laer' going around 'pland' is 'LAPLANDER'.
(Other definitions for laplander that I've seen before include "North European" , "What falls easily to one" , "Northerner?" , "Santa's compatriot?" , "one in the far north" .)
