Usage
Plural word for alumni Alumni is the plural form of the singular noun alumnus. The plurals of several other words ending in -us are also formed in this way, such as fungus/fungi and cactus/cacti. Irregular plurals that are formed like alumni derive directly from their original pluralization in Latin. Specifically, alumnus is the masculine singular form in Latin and alumni is the masculine plural form. The feminine singular form in Latin is alumna and the feminine plural form is alumnae. Sometimes, this distinction is carried over into English. However, alumnus and alumni are both commonly used in a gender-neutral way in English. Alumni is sometimes treated as a singular noun. However, this is not considered valid in standard English, and alumni should be treated as a plural form.
