Inform — educate (9)
I believe the answer is:
enlighten
I believe this is a double definition.
'inform' is the first definition.
(I know that enlighten is a type of clarify)
'educate' is the second definition.
(I've seen this before)
(Other definitions for enlighten that I've seen before include "Free from ignorance" , "Explain" , "free from superstition" , "Impart knowledge to" , "Provide illumination" .)
