Potentate with only one foot? (5)
I believe the answer is:
ruler
'potentate' is the definition.
(I've seen this in another clue)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for ruler that I've seen before include "Emperor - measure" , "Despot perhaps" , "One exercising control" , "King or, president, say" , "It can be used to strike" .)
