Professor (often shortened to Prof.) is an academic rank at most universities and colleges. The word professor comes from Latin. It means a "person who professes", so professors are usually experts in arts or sciences. A professor is a teacher of the highest rank. Professors are often active in research. In many institutions, the job title 'professor' means the same as "instructor".
