Separate summary (8)
I believe the answer is:
abstract
I believe this is a double definition.
'separate' is the first definition.
(thesaurus)
'summary' is the second definition.
(abstract is a kind of summary)
(Other definitions for abstract that I've seen before include "Steal" , "Summary; remove" , "Theoretical; painting" , "Appropriate - theoretical - summary" , "Theoretical, not physical" .)
