A professor is someone who teaches at a college or university. Professor is officially a teacher of the highest rank, above adjuncts and lecturers, but college students can call them all professor.

The Latin origin of the word means “declare publicly,” and professors are responsible for publicly sharing their knowledge with the world, or at least with whoever can afford to pay them for lessons. Although anyone teaching college can be called a professor, it’s really a title that has to be earned by going to graduate school and moving up by being an assistant professor, then associate professor, and finally a full professor.
