In the English language, an honorific is a form of address conveying esteem, courtesy or respect. These can be titles prefixing a person's name, e.g.: Mr, Mrs, Miss, Ms, Mx,Sir, Dr, Lady or Lord, or titles or positions that can appear as a form of address without the person's name, as in Mr President, General, Captain, Father, Doctor or Earl.
Many forms of honorifics are for members of the nobility, clergy, military/naval forces, or royalty, mostly in countries that are monarchies. These include "Your Majesty", "Your Royal Highness" or simply "Your Highness", which are used to address certain members of royalty and "My lord/lady" or "Your Lordship/Ladyship" to address a peer other than a Duke, who is referred to as "Your Grace".
Mr: (/ˈmɪstər/) for men, regardless of marital status, who do not have another professional or academic title. The variant Mister, with the same pronunciation, is sometimes used to give jocular or offensive emphasis, or to address a man whose name is unknown.
"Mr" is used with the name of some offices to address a man who is the office-holder, e.g. "Mr President"; "Mr Speaker", see "Madam" below for the equivalent usage for women.
Miss: (/mɪs/) for girls, unmarried women and (in the UK) married women who continue to use their maiden name (although "Ms" is often preferred for the last two). In the UK, it has traditionally been used in schools to address female teachers, regardless of marital status. It is also used, without a name, to address girls or young women and (in the UK) to address female shop assistants and wait staff.
Mrs: (/ˈmɪsɪz/ in the UK, /ˈmɪsəz/ or /ˈmɪsəs/ in the US generally, or /ˈmɪzəz/ or /ˈmɪzəs/ in the southern US) for married women who do not have another professional or academic title, an abbreviation of Mistress. The variant Missus (/ˈmɪsəz/) is used in the UK to address a woman whose name is unknown. There are examples of professional women who were unmarried using the title Mrs, such as Mrs Crocombe, the Cook at Audley End House in the late 19th century.
Ms: (/mɪz/ or /məz/) for women, regardless of marital status or when marital status is unknown.
Mx: (/mɪks/ or /məks/) a gender-neutral honorific for those who do not wish to specify their gender or who do not identify with Mr/Master or Ms/Mrs/Miss, for example if they are non-binary.
Sir: for men, formally if they have a British knighthood or if they are a baronet (used with first name or full name, never surname alone) or generally (used on its own) as a term of general respect or flattery, when it is equivalent in meaning to "Madam" for women (see below). Also traditionally used to address male teachers in British schools.
Gentleman: Originally a social rank, standing below an esquire and above a Yeoman. The term can now refer to any man of good, courteous conduct. It is only generally used as an honorific form of address in the plural ("gentlemen" if referring to a group of men, or as part of "ladies and gentlemen" if referring to a mixed group), with "sir" (or "ladies and sir") being used for the singular.
Sire: a term of address for a male monarch, previously could be used for a person in a position of authority in general or a lord.
Mistress is an archaic form of address for a woman, equivalent to Mrs. Used on its own, it was used to address the female head of a household. The titles Mrs, Miss and Ms are abbreviations derived from Mistress. The term is no longer commonly used because of its connotative meaning; "mistress" is used to refer to a woman with whom a married man is having an affair.
"Sir", "Madam", and "Ma'am" are commonly used by workers performing a service for the beneficiary of the service, e.g. "May I take your coat, Ma'am?"
"Madam" is used with the name of an office to address a woman who is the office-holder, e.g. "Madam President".
Dame: for women who have been honoured with a British knighthood in their own right. Women (who are not dames) married to knights are commonly referred to as "Lady".
Lord: for male barons, viscounts, earls, and marquesses, as well as some of their children. In some countries judges, especially those of higher rank, are referred to as lords, ladies or lordship/ladyship. (Style: Lordship or My Lord).
Lady: for female peers with the rank of baroness, viscountess, countess, and marchioness, or the wives of men who hold the equivalent titles. By courtesy the title is often also used for wives of Knights and Baronets. (Style: Your Ladyship or My Lady). As a plural, it may be used as an honorific for women generally ("ladies" if referring to a group of women, or as part of "ladies and gentlemen" if referring to a mixed group); "madam" (or "madam and gentlemen") is used in the singular.
Esq: (/ɪˈskwaɪər/) (abbreviation of "esquire") in the UK used postnominally in written addresses for any adult male if no pre-nominal honorific (Mr, Dr, etc.) is used. In the United States it is used in the same manner for lawyers irrespective of sex; usage of "esquire" by a person not licensed to practice in a jurisdiction may be used as evidence of unauthorized practice of law in some cases. May be punctuated "esq" or "esq." following practice for other post-nominals.

Although most all male adults of the LDS church are Elders, the title is reserved for the prior mentioned groups.
Rabbi: In Judaism, a rabbi/ˈræbaɪ/ is an ordained religious officiant or a teacher of Torah. This title derives from the Hebrew word רַבִּי rabi[ˈʁabi], meaning "My Master" (irregular plural רבנים rabanim[ʁabaˈnim]), which is the way a student would address a master of Torah. The word "master" רב rav[ˈʁav] literally means "great one".

Cantor: Generally used for Jewish clergy who lead prayer services on a regular basis.
Chief Rabbi: Generally used for a leading rabbi of a city or country, often known in Hebrew as רב הראשי. Sometimes an honorific title if a community rabbi has an ancestor who served as a chief rabbi of a town, or for a son of a grand rabbi who is heir apparent to the position of grand rabbi and serves a rabbinical role in a Hasidic community. Generally, in such cases, this is known in Hebrew as אב בית דין, meaning "leader of the rabbinical court" (literally "father of the house of law"), and abbreviated אב"ד. May also be titled as גאון אב בית דין or ראש אב בית דין, which would be abbreviated as גאב"ד or ראב"ד. These abbreviations may be rendered in English spelling as Ab"d, Gaava"d, or Raava"d, and will often be called "Rav". Generally the abbreviated title will be followed either by the name of the city or town (including ancestral towns), or the name of the congregation, or when called "Rav" the town or congregation will come before the title. For example, the chief rabbi of the Vien community is known either as "Ab"d Vien" or the "Vienner Rav". In some communities, particularly those from Hungarian and Galician backgrounds, the title is used interchangeably with the title of Grand Rabbi or Admo"r.
Grand Rabbi: The charismatic leader of a Hasidic court or community. Generally known in Hebrew as אדונינו מורינו ורבינו, literally "our lord, our teacher, our rabbi", and abbreviated as אדמו"ר and rendered in English spelling as Admo"r or Rebbe. Generally the abbreviated title will be followed either by the name of the city or town (including ancestral towns), or the name of the congregation, or when called "Rebbe" the town or congregation will come before the title. For example, the grand rabbis of the Boston Hasidic communities would be known as either "Admo"r miBoston" or "Bostoner Rebbe".
