tutored

I'm a little stuck... Click here to teach me more about this clue!

'privately instructed' is the definition.
'tutored' can be an answer for 'instructed' (both can mean taught). I'm not certain of the 'privately' bit.

'do utter nonsense' is the wordplay.
'nonsense' is an anagram indicator.
'do'+'utter'='doutter'
'doutter' anagrammed gives 'TUTORED'.

'to' acts as a link.

Can you help me to learn more?

(Other definitions for tutored that I've seen before include "Was coach" , "Coached" , "Gave private lessons to" , "Instructed" , "Privately taught" .)
