The Origin of Alum or Alumni

The words come from Latin:

• Alumnus (male) and Alumna (female) originally meant “foster child” or “nourished one.”
• Alumni is the plural masculine form; Alumnae is the plural feminine form.
• Over time, English adapted alum as a casual shorthand for alumnus/alumna.

The historical roots explain why using alum for a single person is common in American English, while alumni is used formally for multiple graduates.
