Turned out unusually ignorant (9)
I believe the answer is:
untutored
'ignorant' is the definition.
(thesaurus)
'turned out unusually' is the wordplay.
'unusually' indicates anagramming the letters.
'turned'+'out'='turnedout'
'turnedout' with letters rearranged gives 'UNTUTORED'.
(Other definitions for untutored that I've seen before include "Being ignorant" , "without formal education" , "lacking education" , "Lacking formal teaching" , "lacking refinement" .)
