The other half of Dutch budget (7)
I believe the answer is:
husband
This might be a double definition.
'the other half' is the first definition.
(thesaurus)
'dutch budget' is the second definition.
'husband' can be an answer for 'budget' (thesaurus). I'm unsure of the 'dutch' bit.
'of' is the link.
Can you help me to learn more?
(Other definitions for husband that I've seen before include "Economically manage" , "Use resources economically" , "Groom" , "be economical" , "Make careful use of" .)
