An exponent is a person who is a big promoter of something. Are you an exponent of the four-day school and work week?

You may already know the mathematical meaning of exponent: a numeric notation showing how many times a number is multiplied by itself. How did exponent come to mean a strong advocate or promoter of something? Well, its Latin ancestor was a verb meaning "to put forth" and it's easy to see how this could be generalized to refer to people. After all, aren't you an exponent of freedom of expression?
