# Master (form of address)
**Master** is an English honorific traditionally prefixed to the name of a boy or young man who is not yet old enough to be addressed as Mister (Mr.). It descends from the same word as the everyday noun *master*, Latin *magister* "chief, teacher," and is the older sibling of the modern courtesy title Mr., which developed from it.[1](https://en.wikisource.org/wiki/1911_Encyclop%C3%A6dia_Britannica/Master) • [2](https://www.merriam-webster.com/dictionary/master)
| Key fact | Detail |
|---|---|
| Who it applies to | A male youth or boy too young to be called Mister, used as a title before his name[2](https://www.merriam-webster.com/dictionary/master) |
| Origin | From Latin *magister* "chief, head, teacher," through Old French *maistre* and Old English *mægester*[3](https://www.etymonline.com/word/master) |
| Relation to Mr. | Master was the usual prefix to a man's name; it was corrupted in sound to "mister" and abbreviated to Mr.[1](https://en.wikisource.org/wiki/1911_Encyclop%C3%A6dia_Britannica/Master) |
| 19th-century convention | By the late 19th century, etiquette dictated that men be addressed as Mister and boys as Master[4](https://api.scienceweb.uz/storage/publication_files/5437/15438/6569aae261f21___1.pdf) |
| Current status | Still used for boys in formal contexts, but it now sounds old-fashioned[5](https://dictionary.cambridge.org/us/grammar/british-grammar/names-and-titles) |
| Peerage use | In some Scottish peerages below the rank of earl, Master appears in the courtesy title of the heir, as in the "Master of Ruthven"[1](https://en.wikisource.org/wiki/1911_Encyclop%C3%A6dia_Britannica/Master) |
## Origins
The word reaches English from Latin *magister*, a contrastive adjective meaning "he who is greater," built on *magis* "more." It entered late [Old English](https://www.edgepedia.org/old-english) as *mægester*, a man having control or authority over a place or a teacher of children, and was reinforced in [Middle English](https://www.edgepedia.org/middle-english) by the [Old French](https://www.edgepedia.org/old-french) cognate *maistre* (modern French *maître*).[3](https://www.etymonline.com/word/master) The 1911 Encyclopædia Britannica groups the word's applications into holders of command or authority, holders of public or private offices, and the teacher–pupil or employer–employed relationship, and notes that as a title of address it came to mark a man's name in general use.[1](https://en.wikisource.org/wiki/1911_Encyclop%C3%A6dia_Britannica/Master)
## From Master to Mister
Master was once the ordinary prefix of address to a man's name, though at first confined to people of some social standing. Under the influence of "mistress," its female counterpart, the pronunciation shifted to "mister," and the title was abbreviated to Mr.[1](https://en.wikisource.org/wiki/1911_Encyclop%C3%A6dia_Britannica/Master) The spelling Mister developed into a separate courtesy title for men; the abbreviated Mr. is the form normally written before a name, while the long form mister survives mainly in direct address without a name, as a usually less formal, "low" equivalent of *sir* ("Excuse me, mister, can you help me?").[6](https://www.encyclopedia.com/humanities/encyclopedias-almanacs-transcripts-and-maps/form-address) • [7](https://our-languages.canada.ca/en/writing-tips-plus/mr-mrs-miss-ms)
Once Mister had taken over in common speech, Master was retained as a form of address only for boys who had not yet entered society. By the late 19th century, etiquette writers prescribed Mister for men and Master for boys.[4](https://api.scienceweb.uz/storage/publication_files/5437/15438/6569aae261f21___1.pdf) Etymonline dates the specific boy-title use, as a shortening of "young master," to the late sixteenth century.[3](https://www.etymonline.com/word/master)
## Usage for boys
**Formal correspondence.** Style manuals that prescribe conventional forms of address still list Master for male children: the United States Federal Highway Administration's correspondence manual gives "Master John Doe" as the standard address for ages 1 to 12.[8](https://highways.dot.gov/laws-regulations/directives/orders/correspondence-manual/appendix-c-external-and-internal-forms) A household hierarchy of the [Edwardian era](https://www.edgepedia.org/edwardian-era), recreated in the television series *Manor House*, distinguished within one family between the eldest son addressed as "Mister Jonathan" and the youngest as "Master Guy," with servants referring to third parties as "Master Olliff-Cooper."[9](https://www.pbs.org/manorhouse/edwardianlife/servants_address.html)
The same age distinction once held for women, where Miss marked a girl or unmarried woman and Mrs. a married one; Cambridge's grammar notes that Miss is also becoming less common among younger women.[5](https://dictionary.cambridge.org/us/grammar/british-grammar/names-and-titles)
**Peerage and offices.** In Scottish usage, Master appears in the courtesy title of the heir in some peerages below the rank of earl, such as the Master of Ruthven.[1](https://en.wikisource.org/wiki/1911_Encyclop%C3%A6dia_Britannica/Master) Merriam-Webster records this as a current dictionary sense: the eldest son of a Scottish viscount or baron.[2](https://www.merriam-webster.com/dictionary/master) The title also survives in the master of a college at Oxford and Cambridge, a presiding office rather than a form of address to a boy.[1](https://en.wikisource.org/wiki/1911_Encyclop%C3%A6dia_Britannica/Master)
## Current status and contested institutional uses
Cambridge's usage guidance states plainly that Master now sounds old-fashioned, though it is still occasionally used for boys in formal contexts.[5](https://dictionary.cambridge.org/us/grammar/british-grammar/names-and-titles) Modern American English rarely requires the Master/Mister distinction in ordinary conversation or writing.[10](https://englishrulebook.com/master-vs-mister/)
The word's other meanings have weighed on the title's acceptability in American institutions. A legal analysis of address by [Richard Brooks](https://www.edgepedia.org/richard-brooks) notes that over the history of slavery and slave-like servitude in America, *master* acquired a distinct meaning as a form of address, and that when free to choose, people across social classes rejected the usage; he examines the case of a Yale college head who declined the title Master of Pierson College, where servant-employees of the university had been expected to address the head as "master."[11](https://www.law.nyu.edu/sites/default/files/upload_documents/Richard%20Brooks%20Paper_0.pdf) A commentary in *Time* on the same debate observed that in [American English](https://www.edgepedia.org/american-english) the word "carries a whiff of the plantation and the whip," and that the title at issue was an awkward relic rather than an intended insult.[12](https://time.com/4133650/harvard-master/) Under slavery, enslaved people customarily addressed owners as "master" or its dialect variants "marster" and "mars," usually followed by a first name such as "Mars Bill";[13](https://erenow.org/modern/been-in-the-storm-so-long/6.php) after emancipation, "Boss" and "Cap'n" replaced "Master" in the etiquette of the Jim Crow period.[14](https://jimcrowmuseum.ferris.edu/question/2006/september.htm)
