Take up the summary again, perhaps (6)
I believe the answer is:
resume
'take up' is the definition.
(I know that take up can be written as resume)
'summary again perhaps' is the wordplay.
I cannot quite see how this works, but
'again' could be 're' (prefix meaning 'again') and 're' is present in the answer.
This explanation may well be incorrect...
'the' is the link.
Can you help me to learn more?
(Other definitions for resume that I've seen before include "Start again having taken a break" , "Go on after a pause" , "Re-open" , "Begin the summary again?" , "Carry on where one left off" .)
