What is the term for an experienced person guiding a less experienced person toward a goal?

The term "mentor" refers to an experienced individual who provides guidance, support, and advice to a less experienced person, often in a professional or personal development context. A mentor typically shares knowledge and experiences, helping the mentee navigate challenges and achieve specific goals. This relationship goes beyond mere instruction; it fosters a supportive environment where the mentee can learn, grow, and develop skills under the mentor's guidance.

In contrast, while roles like advisor, coach, and guide can involve elements of teaching and support, they may not encompass the comprehensive, long-term relationship emphasized in mentorship. An advisor usually provides information and recommendations, a coach focuses on performance improvement and often has a more structured approach to training, and a guide typically leads someone through a specific experience or journey, rather than developing a personal relationship aimed at holistic growth. Thus, "mentor" captures the essence of the supportive and developmental relationship described in the question.
