Start again with a summary (6)
I believe the answer is:
resume
I believe this is a double definition.
'start again' is the first definition.
(resume can mean to start doing something again)
'summary' is the second definition.
(I know that resume is a type of summary)
'with a' acts as a link.
(Other definitions for resume that I've seen before include "Start again where one left off" , "Abstract" , "Short descriptive summary" , "Begin the summary again?" , "Speak again" .)
