Nearly threw away page over writer's tip (3,3)
I believe the answer is:
pen nib
'nearly threw away page' is the definition.
I don't know anything about this answer so I cannot tell whether this works.
'over writer's tip' is the wordplay.
'over' says to put letters next to each other.
'writer' becomes 'pen' (something which writes).
'tip' becomes 'nib' (I have seen 'Tip of pen ' mean 'nib' so perhaps 'tip' could also mean 'nib').
'pen'+'nib' is 'PEN-NIB'.
Can you help me to learn more?
(Another definition for pen nib that I've seen is " Point of writing instrument".)
