Stopped moving round on being delayed (9)
I believe the answer is:
postponed
'being delayed' is the definition.
('postponed' can be similar in meaning to 'delayed')
'stopped moving round on' is the wordplay.
'moving' indicates anagramming the letters.
'round' is an insertion indicator.
'stopped' with letters rearranged gives 'postped'.
'postped' going around 'on' is 'POSTPONED'.
(Other definitions for postponed that I've seen before include "Deferred" , "Put off" , "delayed" .)
