Preposition that can help you make a point (4)
I believe the answer is:
into
'preposition' is the definition.
(I've seen this in another clue)
'can help you make a point' is the wordplay.
I cannot really understand how this works, but
'point' could be 'n' (North) and 'n' is found within the answer.
The remaining letters 'ito' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
'that' is the link.
Can you help me to learn more?
(Other definitions for into that I've seen before include "A fan of" , "Keen on, colloquially" , "Four this twelve is three" , "Not I (anag.)" , "Expression of division" .)
