One who’s given to avoid any of the educational basics? (5)

I believe the answer is:
donor
'avoid any of the educational basics?' is the definition.
I can't judge whether this defines the answer.
'one who's given to' is the wordplay.
'one who' becomes 'dr' (from TV series Doctor Who).
'given' indicates putting letters inside.
'to' becomes 'ono' (I can't explain this - if you can you should give a lot more credence to this answer).
'dr' going around 'ono' is 'DONOR'.
Can you help me to learn more?
(Other definitions for donor that I've seen before include "contributor" , "One who gives blood, for instance" , "Generous type" , "One giving to a cause" , "Sponsor" .)
