Take out royal household (5)
I believe the answer is:
court
This clue is a double definition.
'take out' is the first definition.
(both can mean to date someone)
'royal household' is the second definition.
(Other definitions for court that I've seen before include "sovereign's advisers" , "legal building" , "Tennis arena" , "SECOND PART OF 5" , "SECOND PART OF 2" .)
