Cautioned about providing schooling (9)
I believe the answer is:
education
'schooling' is the definition.
(thesaurus)
'cautioned about' is the wordplay.
'about' is an anagram indicator.
'cautioned' is an anagram of 'EDUCATION'.
'providing' acts as a link.
(Other definitions for education that I've seen before include "Theory and practice of teaching" , "Auctioned off learning process" , "Culture" , "what may be completed by degrees" , "Work of master" .)
