A mentee is the person a mentor helps — someone with less experience who is advised and supported, most often at work, in training, or at university. The mentor is the experienced one; the mentee is the one receiving the help. It is office and school English, not family English: you do not usually call a child a mentee of a parent. It feels a little formal. Many people skip the word and say “the person I mentor” instead. The word is fairly new (from about 1958). English speakers looked at mentor, treated the end as if it meant “the one who does it” (like employer), and built mentee with -ee for “the one it is done to” (like employee). Mentor itself is from an old Greek name, so that -or reading was a mistake — but mentee stuck, and it is a real word now.
