Put off after page 1 (8)
I believe the answer is:
postpone
'put off' is the definition.
(I know that put off can be written as postpone)
'after page 1' is the wordplay.
'after' becomes 'post' (prefix meaning after, eg post-war).
'page' becomes 'p'.
'1' becomes 'one' (synonyms).
'post'+'p'+'one'='POSTPONE'
(Other definitions for postpone that I've seen before include "Put off until future date" , "'Hold over, defer (8)'" , "pigeon-hole" , "Put off, defer" , "'Put off, delay (8)'" .)
