Jumble, assortment (7)
I believe the answer is:
mixture
This clue is a double definition.
'jumble' is the first definition.
(thesaurus)
'assortment' is the second definition.
(I know that assortment can be written as mixture)
(Other definitions for mixture that I've seen before include "That which is left" , "Melange" , "Amalgamation" , "Blend" , "Alloy, compound, fusion" .)
