Exact point covered by the summary (7)
I believe the answer is:
precise
'exact' is the definition.
(I know that exact can be written as precise)
'point covered by the summary' is the wordplay.
'point' becomes 'E' (compass point).
'covered by' means one lot of letters go next to another (on top of in a down clue).
'the summary' becomes 'precis' (precis is a kind of summary).
'e' after 'precis' is 'PRECISE'.
(Other definitions for precise that I've seen before include "Recipes (anag.)" , "Detailed, exact" , "Highly accurate and sharply exact" , "Specific" , "with accuracy" .)
