Appropriate summary (8)
I believe the answer is:
abstract
I believe this is a double definition.
'appropriate' 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 "painting by Kandinsky, perhaps" , "Rothko work?" , "Half-inch" , "Steal" , "Extract; summary" .)
