French royal biscuit (7)
I believe the answer is:
bourbon
This might be a double definition.
'french royal' is the first definition.
The definition and answer can be both people as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'biscuit' is the second definition.
(I've seen this before)
Can you help me to learn more?
(Other definitions for bourbon that I've seen before include "Chocolate-flavoured biscuit" , "10" , "Rye whisky; biscuit" , "Rye whiskey" , "Corn whiskey" .)
