The end of a fox
I believe the answer is:
brush
This might be a double definition.
'the end' is the first definition.
The definition and answer can be both acts as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'a fox' is the second definition.
Although both the answer and definition are singular nouns, I don't see how they can define each other.
'of' is the link.
Can you help me to learn more?
(Other definitions for brush that I've seen before include "Cleaning implement" , "Undergrowth, fox tail" , "Sweeping implement" , "Tool for cleaning or painting" , "Sweep" .)
