A less than strictly accurate summary? (6)
I believe the answer is:
precis
'summary?' is the definition.
(I know that precis is a type of sum-up)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for precis that I've seen before include "Prices for a summary" , "Digest - summary" , "Summary of the main points" , "Summary, short version" , "Abstract; make summary (of text)" .)
