Yields to others wishes and arranges a postponement (6)
I believe the answer is:
defers
'yields' is the definition.
(deferring is a kind of yielding)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for defers that I've seen before include "Puts off to another time" , "Puts off or submits" , "Yield to another's wish" , "Gives precedence (to)" , "Puts off till a later time" .)
