Alumni can be used to refer to men only, and in that case alumnae is used to refer to women only, but more often alumni is used to refer to either or both sexes where both attend the same school. The singular forms are alumnus for a man, and alumna for a woman. An alumnus or an alumna of a college, university, or other school is a former student who has either attended or graduated in some fashion from the institution. The word is Latin and simply means student. The plural is alumni for men and mixed groups and alumnae for women. The term is not synonymous with "graduate"; one can be an alumnus without graduating alumnus but not graduate of An "alumnus" can also be, and has more recently been expanded to include, a former employee of an organization and may also apply to a former member, contributor, or inmate.
