Plans happening is likely (7)

I believe the answer is:
intends
'plans' is the definition.
(intending is a kind of planning)
'happening is likely' is the wordplay.
I cannot really understand how this works, but
'happening' could be 'end' (end is a kind of happening) and 'end' is found in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for intends that I've seen before include "Has as a purpose" , "Plans, means" , "Aims" .)
