Wipe out aid - create confusion (9)
I believe the answer is:
eradicate
'wipe out' is the definition.
(I know that wipe out can be written as eradicate)
'aid create confusion' is the wordplay.
'confusion' indicates anagramming the letters.
'aid'+'create'='aidcreate'
'aidcreate' with letters rearranged gives 'ERADICATE'.
(Other definitions for eradicate that I've seen before include "Excise" , "Scotch" , "Exterminate, extinguish" , "Expunge" , "scratch" .)
