Look beyond page two (4)
I believe the answer is:
pair
'two' is the definition.
(pair is a kind of two)
'look beyond page' is the wordplay.
'look' becomes 'air' (I've seen this before).
'beyond' says to put letters next to each other.
'page' becomes 'p'.
'air' after 'p' is 'PAIR'.
(Other definitions for pair that I've seen before include "Agreement to avoid division" , "Two of a similar type" , "Two of a kind, as in cards" , "Twins" , "Put together - two of a kind" .)
