Admonished as a result of bad education (9)
I believe the answer is:
cautioned
'admonished' is the definition.
('caution' can be a synonym of 'admonish')
'bad education' is the wordplay.
'bad' is an anagram indicator.
'education' with letters rearranged gives 'CAUTIONED'.
'as a result of' acts as a link.
(Other definitions for cautioned that I've seen before include "Gave warning" , "Education (anag)" , "Warned by way of education" , "Given formal warning" .)
