Put off, postpone (5)
I believe the answer is:
defer
This clue is a double definition.
'put off' is the first definition.
(I know that put off can be written as defer)
'postpone' is the second definition.
(I know that postpone can be written as defer)
(Other definitions for defer that I've seen before include "Capitulate" , "Allow precedence (to)" , "Bow?" , "Play for time" , "Put off till later" .)
