One doesn't appear to be educated (6)
I believe the answer is:
truant
'educated' is the definition.
Both the answer and definition are adjectives. Perhaps there's an association between them I don't understand?
'one doesn't appear to be' is the wordplay.
I cannot quite see how this works, but
'one' could be 'an' (an apple is one apple) and 'an' is found in the answer.
'be' could be 'rut' (rutting is a kind of being) and 'rut' is found in the leftover letters.
A single letter 't' remains which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for truant that I've seen before include "Pupil who stays away from school with permission" , "Runaway" , "Straying" , "Pupil away from school without leave" , "'Bunk off'" .)
