Lorado Taft's Alma Mater in Urbana, Illinois

Alumni (singular: alumnus (masculine) or alumna (feminine)) are people who used to be students of a school, college, or university who have either attended or graduated in some way from the institution.

The Latin noun alumnus means "foster son" or "pupil" and comes from the verb alere "to nourish".
