From Merrian-Webster:

Main Entry: men·tor
Pronunciation: \ˈmen-ˌtȯr, -tər\
Function: noun
Etymology: Latin, from Greek Mentōr
Date: 1616
1 capitalized : a friend of Odysseus entrusted with the education of Odysseus' son Telemachus
2 a : a trusted counselor or guide b : tutor, coach

To me, a mentor is someone who interacts with the students on the team. Whether that interaction is showing them how to build a robot, how to submit an award, how to organize a dinner, how to act graciously towards others, or tutoring Odysseus's son, you are still mentoring.

Part of the NEM/EM dichotomy is expressed in the description of the WFA:

"The Woodie Flowers Award celebrates effective communication in the art and science of engineering and design. Dr. William Murphy founded this prestigious award in 1996 to recognize mentors who lead, inspire and empower using excellent communication skills."

I think they are trying to expand the award to NEMs, but still can't quite get away from the engineering mindset.
