Emeritus is an adjective that is used in the title of a retired professor, bishop or other professional. Emerita was used for women, but is rarely used today. The term is used when a person of importance in a given profession retires, so that his or her former rank can still be used in his or her title. This is particularly useful when establishing the authority a person might have to comment, lecture or write on a particular subject....The word is always associated with the title, not the name, of a person. For example, "Professor Emeritus of Mathematics Alex Robertson."  Emeritus does not imply that the person must be retired from all duties of his or her previous title. Nor does it imply that the person is engaged in the duties of his or her previous title. ---From AskDefine.com

 

A Professor Emeritus is a full professor who retires in good standing. This title is also given to retired professors who continue to teach and to be listed; they may also draw a very large percentage of their last salary as pension. The title may also be given to full professors who have left for another institution but are still working full time. The concept has in some places been expanded to include also tenured associate professors. In some 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. Depending on local circumstances Emeritus Professors may retain their offices and/or other privileges in order to remain active in the academic community of an institution as a mentor or subject matter expert.  ---From Wikipedia
