Turning over a couple of pages before you sanction it (7)
I believe the answer is:
approve
'you sanction it' is the definition.
I can't judge whether this defines the answer.
'turning over a couple of pages before' is the wordplay.
'turning' indicates an anagram.
'couple of' shows that letters should be duplicated.
'pages' becomes 'p' ().
'before' means one lot of letters go next to another.
'p' duplicated is 'pp'.
'over' is an anagram of 'rove'.
'a'+'pp'='app'
'rove' after 'app' is 'APPROVE'.
Can you help me to learn more?
(Other definitions for approve that I've seen before include "Agree" , "permit" , "Say yes to" , "Confirm" , "Deem satisfactory" .)
