Get rid of extra tip foolish European added (9)
I believe the answer is:
extirpate
'get rid of' is the definition.
(to extirpate is to get rid of or destroy)
'extra tip foolish european added' is the wordplay.
'foolish' is an anagram indicator.
'european' becomes 'E' (abbreviation e.g. EU).
'added' means one lot of letters go next to another.
'extra'+'tip'='extratip'
'extratip' anagrammed gives 'extirpat'.
'extirpat'+'e'='EXTIRPATE'
(Other definitions for extirpate that I've seen before include "Completely destroy" , "destroy utterly" , "Destroy totally" , "Remove completely" , "Root out" .)
