A couple of pages, right shape, getting consent (8)
I believe the answer is:
approval
'consent' is the definition.
(I've seen this before)
'a couple of pages right shape' is the wordplay.
'couple of' indicates the doubling of some letters.
'pages' becomes 'p'.
'right' becomes 'r' (common abbreviation).
'shape' becomes 'oval' (oval is a kind of shape).
'p' duplicated is 'pp'.
'a'+'pp'+'r'+'oval'='APPROVAL'
'getting' is the link.
(Other definitions for approval that I've seen before include "Confirmation" , "Favourable judgement" , "Official consent, authorisation" , "Favourable opinion or official permission" , "Green light" .)
