Origin of alumnusLatin, pupil, from alere, to nourish; see al-2 in Indo-European roots. Usage Note: Alumnus and alumna both come from Latin and preserve Latin plurals. Alumnus is a masculine noun whose plural is alumni, and alumna is a feminine noun whose plural is alumnae. Coeducational institutions usually use alumni for graduates of both sexes. But those who object to masculine forms in such cases may prefer using alumni and alumnae, alumnae/i, or the more casual alums. The word graduates also presents a gender-neutral alternative.
Alumnus is used when the gender of the subject is unspecified.
- Any alumnus may be invited to the reunion.
Borrowed from Latin alumnus (literally “foster child, nourished one”).
