ALUMNI VS. ALUMNUS VS. ALUM VS. ALUMNA VS. ALUMNAE

What’s the difference between alumni and alumnus?

An alumnus is a graduate of a school, such as a high school or university. The plural of alumnus is alumni (which follows the plural ending construction used in other Latin-derived words, like stimulus and stimuli).

In Latin, alumnus specifically refers to a male graduate, and sometimes this distinction is carried into English, with alumna being used to refer to a female graduate. The plural of alumna is alumnae.

Still, alumnus and alumni are both commonly used in a gender-neutral way.

The informal shortening alum is used to refer to a single graduate (regardless of gender). It’s sometimes pluralized as alums.

Here’s an example of alumni and alumnus used correctly in the same sentence.

Example: As an alumnus, you share something with all of the alumni, regardless of when each of you graduated.
