Trained, taught (7)
I believe the answer is:
tutored
I believe this is a double definition.
'trained' is the first definition.
(I've seen this before)
'taught' is the second definition.

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