Ran over and talked foolishly about European (8)
I believe the answer is:
operated
'ran' is the definition.
('operate' can be a synonym of 'run')
'over and talked foolishly about european' is the wordplay.
'over' becomes 'o' (cricket abbreviation).
'and' means one lot of letters go next to another.
'talked foolishly' becomes 'prated' (to prate is to talk foolishly).
'about' means one lot of letters goes inside another.
'european' becomes 'E' (abbreviation e.g. EU).
'prated' placed around 'e' is 'perated'.
'o'+'perated'='OPERATED'
(Other definitions for operated that I've seen before include "Functioned" , "Performed surgery or worked a machine" , "'Directed or controlled, machinery say (8)'" , "ran" , "Adore pet (anag.)" .)
