Carry on a summary (6)
I believe the answer is:
resume
I believe this is a double definition.
'carry on' is the first definition.
(I know that resume is a kind of carry on)
'a summary' is the second definition.
(I know that resume is a type of summary)
(Other definitions for resume that I've seen before include "proceed" , "Begin the summary again?" , "Carry on (with something adjourned)" , "Short descriptive summary" , "Continue after a break" .)
