Assorted nuts covering each throw (6)
I believe the answer is:
unseat
'throw' is the definition.
(thesaurus)
'assorted nuts covering each' is the wordplay.
'assorted' indicates anagramming the letters.
'covering' means one lot of letters goes inside another.
'each' becomes 'ea'.
'nuts' is an anagram of 'unst'.
'unst' placed around 'ea' is 'UNSEAT'.
(Other definitions for unseat that I've seen before include "Get out of office" , "Cause to fall from the saddle" , "Remove from power" , "Throw (as a 15?)" , "Remove from horse (or house?)" .)
