Maybe phrase looks wrong on page (7)
I believe the answer is:
perhaps
'maybe' is the definition.
('perhaps' can be a synonym of 'maybe')
'phrase looks wrong on page' is the wordplay.
'looks wrong' is an anagram indicator.
'on' is an insertion indicator (as in clothing \'on\' a person).
'page' becomes 'p'.
'phrase' is an anagram of 'perhas'.
'perhas' going around 'p' is 'PERHAPS'.
(Other definitions for perhaps that I've seen before include "say" , "Possibly but not certainly" , "Could be, maybe" , "It may be" , "Not necessarily" .)
