A teacher is an example of a mentor.
Origin of mentor
- French Mentor Mentor from Latin Mentōr from Greek men-1 in Indo-European roots
From American Heritage Dictionary of the English Language, 5th Edition
- From French mentor, from Ancient Greek Μέντωρ (Mentōr, “Mentor"), a mythological character in the Odyssey, whose name, a historical name from Ancient Greece, may share the same root as English mind. Akin to Sanskrit मन्तृ (mantá¹›, “one who thinks") and Latin monitor (“one who admonishes"), and perhaps ultimately from Proto-Indo-European *mon-eyo-, causative form of *men- (“to think").
