One hopes people will come late to this meeting (6)
I believe the answer is:
seance
'this meeting' is the definition.
(seance is a kind of meeting)
'one hopes people will come late' is the wordplay.
I cannot really understand how this works, but
'one' could be 'an' (an apple is one apple) and 'an' is found within the answer.
This may be the basis of the clue (or it may be nonsense).
'to' acts as a link.
Can you help me to learn more?
(Other definitions for seance that I've seen before include "Medium experience?" , "Dead-contacting meeting" , "Dead rousing session" , "Encase (anag)" , "Spiritualists meeting with medium" .)
