An honorific is a title that conveys esteem, courtesy, or respect for position or rank when used in addressing or referring to a person. Sometimes, the term "honorific" is used in a more specific sense to refer to an honorary academic title. It is also often conflated with systems of honorific speech in linguistics, which are grammatical or morphological ways of encoding the relative social status of speakers. Honorifics can be used as prefixes or suffixes depending on the appropriate occasion and presentation in accordance with style and customs.

Typically, honorifics are used as a style in the grammatical third person, and as a form of address in the second person. Use in the first person by the honored dignitary, outside a relevant context, is uncommon or often considered very rude and egotistical. Some languages have anti-honorific (despective or humilific) first person forms (expressions such as "your most humble servant" or "this unworthy person") whose effect is to enhance the relative honor accorded to the person addressed.
