Relating to the Netherlands (5)
I believe the answer is:
dutch
'relating to the netherlands' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for dutch that I've seen before include "People of the Netherlands" , "A European; pay-for-oneself (treat)" , "Relating to the Netherlands" , "Better half" , "& 7 Alcohol-induced nerve" .)
