Emeritus (//; female: Emerita),[Note 1] in its current usage, is an adjective used to designate a retired chair, professor, pastor, bishop, pope, director, president, prime minister, rabbi, emperor, or other person who has been "permitted to retain as an honorary title the rank of the last office held".
In some cases, the term is conferred automatically upon all persons who retire at a given rank, but in others, it remains a mark of distinguished service, awarded only to a few on retirement. It is also used when a person of distinction in a profession retires or hands over the position, enabling their former rank to be retained in their title, e.g., "professor emeritus". The term emeritus does not necessarily signify that a person has relinquished all the duties of their former position, and they may continue to exercise some of them.
Emeritus (past participle of Latin emerere, meaning "complete one's service") is a compound of the Latin prefix e- (variant of ex-) meaning "out of, from" and merere (source of "merit") meaning "to serve, earn". The word is attested since the early 17th century with the meaning "having served out one's time, having done sufficient service." The Latin feminine equivalent, emerita (//), is also sometimes used, however, in English the word emeritus is often unmarked for gender.
In the United States and other countries, a tenured full professor who retires from an educational institution in good standing may be given the title "professor emeritus". The title "professor emerita" is sometimes used for women. In most systems and institutions, the rank is bestowed on all professors who have retired in good standing, while at others, it needs a special act or vote. Professors emeriti may, depending on local circumstances, retain office space or other privileges. The adjective may be placed before or after the title, e.g., "professor emeritus" or "emeritus professor".

When a diocesan bishop or auxiliary bishop retires, the word emeritus is added to his former title, i.e., "Archbishop Emeritus of ...". The term "Bishop Emeritus" of a particular see can apply to several people, if the first lives long enough. The title was applied to the Bishop of Rome, Pope Emeritus Benedict XVI, on his retirement. In Community of Christ, the status of emeritus is occasionally granted to senior officials upon retirement. In Judaism, emeritus is often a title granted to long-serving rabbis of synagogues or other Jewish institutions. In some cases, the title is also granted to chazzans. Rabbi Emeritus or Cantor Emeritus is largely an honorific title.
