Share of profit split with north Germany (8)
I believe the answer is:
dividend
'share of profit' is the definition.
(I've seen this before)
'split with north germany' is the wordplay.
'split' becomes 'divide' ('divide' can be a synonym of 'split'**).
'with' says to put letters next to each other.
'north' becomes 'n' ('N' can be a synonym of 'north').
'germany' becomes 'd' (international vehicle registration code).
'divide'+'n'+'d'='DIVIDEND'
(Other definitions for dividend that I've seen before include "Number to be divided, or share of profits" , "Payout on shares" , "Bonus share of a surplus" , "A share of profits paid to shareholders (8)" , "Payment to shareholder" .)
