Invent, contrive (7)
I believe the answer is:
concoct
I believe this clue is a double definition.
'invent' is the first definition.
(concocting is a kind of inventing)
'contrive' is the second definition.
(thesaurus)
(Other definitions for concoct that I've seen before include "Invent (a story/plan)" , "Invent (a story)" , "cook" , "Invent, devise" , "Fabricate" .)
