History


Ancient Greek origin

The full stop symbol derives from the Greek punctuation introduced by
Aristophanes of Byzantium __NOTOC__ Aristophanes of Byzantium ( grc-gre, Ἀριστοφάνης ὁ Βυζάντιος ; BC) was a Hellenistic Greek scholar, critic and grammarian, particularly renowned for his work in Homeric scholarship, but also for work on other ...
in the 3rd century . In his system, there were a series of dots whose placement determined their meaning.


''stigmḕ teleía'', ''stigmḕ mésē'' and ''hypostigmḕ''

The full stop at the end of a completed thought or expression was marked by a high dot ⟨˙⟩, called the ''stigmḕ teleía'' () or "terminal dot". The "middle dot" ⟨·⟩, the ''stigmḕ mésē'' (), marked a division in a thought occasioning a longer breath (essentially a

In practice, scribes mostly employed the terminal dot; the others fell out of use and were later replaced by other symbols. From the 9th century onwards, the full stop began appearing as a low mark (instead of a high one), and by the time

were consistent in their usage of the terms ''period'' and ''full stop''. The word ''period'' was used as a name for what printers often called the "full point", the punctuation mark that was a dot on the baseline and used in several situations. The phrase ''full stop'' was only used to refer to the punctuation mark when it was used to terminate a sentence. This terminological distinction seems to be eroding. For example, the 1998 edition of '' Fowler's Modern English Usage'' used ''full point'' for the mark used after an abbreviation, but ''full stop'' or ''full point'' when it was employed at the end of a sentence; the 2015 edition, however, treats them as synonymous (and prefers ''full stop''), and '' New Hart's Rules'' does likewise (but prefers ''full point''). Essentially the same text is found in the previous edition under various titles, including ''New Hart's Rules'', ''Oxford Style Manual'', and ''The Oxford Guide to Style''. In 1989, the last edition (1989) of the original ''Hart's Rules'' (before it became ''

Usage

Full stops are the most commonly used punctuation marks; analysis of texts indicate that approximately half of all punctuation marks used are full stops.


Ending sentences

Full stops indicate the end of sentences that are not questions or exclamations.


After initials

It is usual in North American English to use full stops after initials; e.g. A. A. Milne, George W. Bush. British usage is less strict. A few style guides discourage full stops after initials. However, there is a general trend and initiatives to spell out names in full instead of abbreviating them in order to avoid ambiguity.


Abbreviations

A full stop is used after some
abbreviation An abbreviation (from Latin ''brevis'', meaning ''short'') is a shortened form of a word or phrase, by any method. It may consist of a group of letters or words taken from the full version of the word or phrase; for example, the word ''abbrevia ...
s. If the abbreviation ends a declaratory sentence there is no additional period immediately following the full stop that ends the abbreviation (e.g. "My name is Gabriel Gama, Jr."). Though two full stops (one for the abbreviation, one for the sentence ending) might be expected, conventionally only one is written. This is an intentional omission, and thus not

, which is unintentional omission of a duplicate. In the case of an interrogative or exclamatory sentence ending with an abbreviation, a question or exclamation mark can still be added (e.g. "Are you Gabriel Gama Jr.?").


Abbreviations and personal titles of address

According to the ''Oxford A–Z of Grammar and Punctuation'', "If the abbreviation includes both the first and last letter of the abbreviated word, as in 'Mister' Mr'and 'Doctor' Dr' a full stop is not used." This does not include, for example, the standard abbreviations for titles such as ''Professor'' ("Prof.") or ''Reverend'' ("Rev."), because they do not end with the last letter of the word they are abbreviating. In
American English American English, sometimes called United States English or U.S. English, is the set of varieties of the English language native to the United States. English is the most widely spoken language in the United States and in most circumstances ...
, the common convention is to include the period after all such abbreviations.


Acronyms and initialisms

In acronyms and initialisms, the modern style is generally to not use full points after each initial (e.g.: ''DNA'', ''UK'', ''USSR''). The punctuation is somewhat more often used in American English, most commonly with ''U.S.'' and ''U.S.A.'' in particular. However, this depends much upon the house style of a particular writer or publisher. As some examples from American style guides, '' The Chicago Manual of Style'' (primarily for book and academic-journal publishing) deprecates the use of full points in acronyms, including ''U.S.'', while ''

Mathematics

The period glyph is used in the presentation of numbers, but in only one of two alternate styles at a time. In the more prevalent usage in English-speaking countries, the point represents a decimal separator, visually dividing whole numbers from fractional (decimal) parts. The comma is then used to separate the whole-number parts into groups of three digits each, when numbers are sufficiently large. * 1.007 (one and seven thousandths) * 1,002.007 (one thousand two and seven thousandths) * 1,002,003.007 (one million two thousand three and seven thousandths) The more prevalent usage in much of Europe, southern Africa, and Latin America (with the exception of Mexico due to the influence of the United States), reverses the roles of the comma and point, but sometimes substitutes a ( thin-)space for a point. * 1,007 (one and seven thousandths) * 1.002,007 or 1 002,007 (one thousand two and seven thousandths) * 1.002.003,007 or 1 002 003,007 (one million two thousand three and seven thousandths) (To avoid problems with spaces, another convention sometimes used is to use

The end of a sentence would be marked by ''STOP''; its use "in telegraphic communications was greatly increased during the World War, when the Government employed it widely as a precaution against having messages garbled or misunderstood, as a result of the misplacement or emission of the tiny dot or period."


In conversation

In British English, the words "full stop" at the end of an utterance strengthen it; they indicate that it admits of no discussion: "I'm not going with you, full stop." In American English the word "period" serves this function. Another common use in African-American Vernacular English is found in the phrase "And that's on period" which is used to express the strength of the speaker's previous statement, usually to emphasise an opinion.

The point as a time separator is also used in Irish English, particularly by the Raidió Teilifís Éireann (RTÉ), and to a lesser extent in Australian, Cypriot, Maltese, New Zealand, South African and other Commonwealth English varieties outside Canada.


Punctuation styles when quoting

The practice in the United States and Canada is to place full stops and commas inside quotation marks in most styles. In the British system, which is also called "logical quotation", full stops and commas are placed according to grammatical sense: This means that when they are part of the quoted material, they should be placed inside, and otherwise should be outside. For example, they are placed outside in the cases of words-as-words, titles of short-form works, and quoted sentence fragments. * Bruce Springsteen, nicknamed "the Boss," performed "American Skin." (closed or American style) * Bruce Springsteen, nicknamed "the Boss", performed "American Skin". (logical or British style) * He said, "I love music." (both) There is some national crossover. American style is common in British fiction writing. British style is sometimes used in American English. For example, the Chicago Manual of Style recommends it for fields where comma placement could affect the meaning of the quoted material, such as linguistics and textual criticism. Use of placement according to logical or grammatical sense, or "logical convention", now the more common practice in regions other than North America, was advocated in the influential book '' The King's English'' by Fowler and Fowler, published in 1906. Prior to the influence of this work, the typesetter's or printer's style, or "closed convention", now also called American style, was common throughout the world.


Spacing after a full stop

There have been a number of practices relating to the spacing after a full stop. Some examples are listed below: * One word space ("

typesetting practices (until the early 20th century). It has also been used in other typesetting systems such as the Linotype machine and the TeX system. Modern computer-based digital fonts can adjust the spacing after terminal punctuation as well, creating a space slightly wider than a standard word space.
