Eventually say the main thing is to reach the tip (3,2,3,5)
I believe the answer is:
get to the point
'eventually say the main thing is' is the definition.
I don't know anything about this answer so I can't tell whether this works.
'reach the tip' is the wordplay.
'reach' becomes 'get to' (getting to is a kind of reaching).
'tip' becomes 'point' (both can mean the end of something).
'getto'+'the'+'point'='GET TO THE POINT'
'to' is the link.
Can you help me to learn more?
(Another definition for get to the point that I've seen is " Stop waffling!".)
