Eliminate misuse of "Frog" with edit (3,3,2)
I believe the answer is:
get rid of
'eliminate' is the definition.
('get rid of' can be a synonym of 'eliminate')
'misuse of frog with edit' is the wordplay.
'misuse of' indicates an anagram (I've seen this in other clues).
'with' says to put letters next to each other.
'frog' after 'edit' is 'editfrog'.
'editfrog' with letters rearranged gives 'GET RID OF'.
(Other definitions for get rid of that I've seen before include "Cause to go away or throw out" , "dump" , "Shrug off" , "sack someone else?" .)
