Pre-nominal letters are a title which is placed before the name of a person as distinct from a post-nominal title which is placed after the name. Examples of pre-nominal titles, for instance professional titles include: Doctor, Captain, Eur Ing (European Engineer), Ir (Ingenieur), CA (Indian Chartered Accountant) and Professor; whilst other common social titles are Mr., Master, The Honorable, Ms., Mrs. and Miss. Pre-nominal letters are generally social, but can be professional in nature (e.g. Eur Ing).
