Junior (suffix)

A name suffix, in the Western English-language naming tradition, follows a person's full name and provides additional information about the person. Post-nominal letters indicate that the individual holds a position, educational degree, accreditation, office, or honor (e.g. "PhD", "CCNA", "OBE"). Other examples include generational designations like "Sr." and "Jr." (or often "Snr" and "Jnr" in British English) and "III", and legal ones such as "Estate" and (French) Feme Covert.

Academic suffixes indicate the degree earned at a college or university. These include the bachelor's degree (A.B, B.A., B.S., B.E., B.F.A., B.Tech., L.L.B, B.Sc., etc.), the master's degree (M.A., M.S., M.F.A., LL.M, M.L.A., M.B.A., M.Sc., M.Eng etc.), the professional doctorate (J.D., M.D., D.O., Pharm.D., etc.), and the academic doctorate (Ph.D., Ed.D., D.Phil., D.B.A., LL.D, Eng.D., etc.).

In the case of doctorates, either the prefix (e.g. "Dr." or "Atty.") or the suffix (e.g. "J.D.", "M.D.", "D.O.", "D.C.", or "Ph.D.") is used, not both. In the United States, the suffix is the preferred format (thus allowing differentiation between types of doctorate) in written documentation.

Such titles may be given by:

The style Esq. or Esquire was once used to distinguish a man who was an apprentice to a knight and is used for a man of socially high ranking. In the United States, Esq. is used as a professional styling for a lawyer. In the United Kingdom, it is used by untitled males in social and business contexts, or occasionally by an untitled male heir to a hereditary peer.
