A couple of pages are not clear (8)
I believe the answer is:
apparent
'clear' is the definition.
('apparent' can be a synonym of 'clear')
'a couple of pages are not' is the wordplay.
'couple of' indicates the doubling of some letters.
'pages' becomes 'p'.
'not' becomes 'nt' ('n't' can be a synonym of 'not'**).
'p' doubled is 'pp'.
'a'+'pp'+'are'+'nt'='APPARENT'
(Other definitions for apparent that I've seen before include "Readily perceived" , "Seeming real or true" , "Noticeable" , "cut , book written on a page" , "Obvious, evident" .)
