The Reverend is an honorific style given before the names of certain Christian clergy and ministers. There are sometimes differences in the way the style is used in different countries and church traditions. The Reverend is correctly called a style, but is sometimes referred to as a title, form of address, or title of respect. The style is also sometimes used by leaders in other religions such as Judaism and Buddhism.

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.
