Honour your leader and submit (4)
I believe the answer is:
'submit' is the definition.
'honour your leader' is the wordplay.
'honour' becomes 'obe' (**).
'leader' says to take the initial letters.
The initial letter of 'your' is 'y'.
'and' is the link.
(Other definitions for obey that I've seen before include "Do as one's told" , "Carry out (orders)" , "Accept instructions" , "Abide by" , "Be dominated" .)
