Monarch with only one foot? (5)
I believe the answer is:
ruler
This clue might be a double definition.
'monarch' is the first definition.
(I've seen this before)
'only one foot?' is the second definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'with' is the link.
Can you help me to learn more?
(Other definitions for ruler that I've seen before include "liner?" , "Measuring rod; governor" , "King, president etc." , "Queen maybe" , "One measures" .)
