Encourage move forward with leader stepping down (4)
I believe the answer is:
urge
'encourage' is the definition.
(I know that urge is a more specific form of encourage)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for urge that I've seen before include "Sudden inclination to do something" , "Advocate" , "Strong, restless desire" , "Appeal to" , "Propel, drive onward" .)
