Alma Mater

Alma Mater is a Latin phrase meaning 'nourishing mother'. However, in English it is used to mean an educational institution, classically a college, or an anthem or fight song of an educational institution.

Usually in the sense of an educational institution, the term is used in reference to an institution which someone has personally attended, as in “at my alma mater, they didn't offer many science courses.” When the term is used to describe an anthem, the speaker need not have attended the institution in question.
