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

'inform' is the definition.
(I know that educate is a kind of instruct)

I can't explain the remainder of the clue.

(Other definitions for educate that I've seen before include "Train, instruct" , "Train, teach" , "Impart knowledge" , "teaching style" , "Give instruction to" .)

I've seen this clue in The Sun.
