Guide to Styles of Address

This guide outlines the traditional manner of addressing and referring to others, in both speech and writing, according to social and official rank. The use of formal styles is courteous but never obligatory, and readers are free to employ them or not, at their own discretion.

In the table below, alternatives are separated by slashes, in decreasing order of formality; square brackets enclose optional wording. If a person falls under multiple headings, the highest applies.

* Some Marquesses’, Earls’ and Viscounts’ titles include the word “of” (e.g. Marquess of Thalano, Countess of Ranell) and some do not (e.g. Viscountess Verdandi, Viscount Le Héricy). It is also possible for the title to include a territorial designation (e.g. Earl Denison of Holt, Viscountess Walker of Rallathy); these are treated as titles without “of”.

** In this instance, “Mayako” is the given name and “Kimura” the surname. Regardless of name order, the given name should always be used with “Lord”, “Lady” and “Sir”.

*** In this instance, “ibn Muhammad” is a patronymic, not a surname; “Mr. Muhammad” would be incorrect.
