With page missing, took it as read and carried on (7)
I believe the answer is:
resumed
'carried on' is the definition.
(I've seen this before)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for resumed that I've seen before include "Recommenced" , "got to work on again" , "Carried on again" , "Restarted" , "Once again picked up" .)
