127-544: The TARDIS ( / ˈ t ɑːr d ɪ s / ; acronym for "Time And Relative Dimension(s) In Space") is a fictional hybrid of a time machine and spacecraft that appears in the British science fiction television series Doctor Who and its various spin-offs. While a TARDIS is capable of disguising itself, the exterior appearance of the Doctor's TARDIS typically mimics a police box , an obsolete type of telephone kiosk that
254-590: A cloaking mechanism (later referred to as the "chameleon circuit") was devised to explain this. In the first episode, An Unearthly Child (1963), the TARDIS is first seen hidden in a London scrapyard in 1963, and after travelling back in time (" The Cave of Skulls ") to the Paleolithic era , the police box exterior persists. In a subsequent story, The Time Meddler (1965), the First Doctor explains that

The European Space Agency has sent 3,000 tardigrades ("water bears") into orbit on the outside of a rocket; 32% survived. The experiment was named Tardigrades in Space, or Tardis. Cultural references to the TARDIS are many and varied. In music, The KLF (performing as "The Timelords") released
508-428: A numeronym . For example, "i18n" abbreviates " internationalization ", a computer-science term for adapting software for worldwide use; the "18" represents the 18 letters that come between the first and the last in "internationalization". Similarly, "localization" can be abbreviated "l10n"; " multilingualization " "m17n"; and " accessibility " "a11y". In addition to the use of a specific number replacing that many letters,
635-645: A single word ("television" or "transvestite", for instance), and is in general spelled without punctuation (except in the plural). Although "PS" stands for the single English word " postscript " or the Latin postscriptum , it is often spelled with periods ("P.S.") as if parsed as Latin post scriptum instead. The slash ('/', or solidus ) is sometimes used to separate the letters in an acronym, as in "N/A" ("not applicable, not available") and "c/o" ("care of"). Inconveniently long words used frequently in related contexts can be represented according to their letter count as
762-669: A "perception filter" that causes people to ignore it, thinking that it is normal. In another episode, it also has a function called the Hostile Action Displacement System (H.A.D.S), which makes it teleport away if it senses danger and will not return until after the danger is dealt with. In the 60th anniversary special " The Giggle ", the Fifteenth Doctor created a copy of TARDIS for the Fourteenth Doctor . Responding to speculation that

It is an unsettled question in English lexicography and style guides whether it is legitimate to use the word acronym to describe forms that use initials but are not pronounced as a word. While there is plenty of evidence that acronym is used widely in this way, some sources do not acknowledge this usage, reserving
1016-459: A Time Lord who goes by the name of the Doctor . TARDISes are built with a "chameleon circuit", a type of camouflage technology that changes the exterior form of the ship to blend into the environment of whatever time or place it lands in. The Doctor's TARDIS always resembles a 1960s London police box , an object that was very common in Britain at the time of the show's first broadcast. Owing to

In the two-part serial The Temptation of Sarah Jane Smith (2008), Sarah Jane becomes trapped in 1951 and briefly mistakes an actual police public call box for the Doctor's TARDIS (the moment is even heralded by the Doctor's musical cue, frequently used in the revived series). It makes
1270-625: A different meaning. Medical literature has been struggling to control the proliferation of acronyms, including efforts by the American Academy of Dermatology. Acronyms are often taught as mnemonic devices: for example the colors of the rainbow are ROY G. BIV (red, orange, yellow, green, blue, indigo, violet). They are also used as mental checklists: in aviation GUMPS stands for gas-undercarriage-mixture-propeller-seat belts. Other mnemonic acronyms include CAN SLIM in finance, PAVPANIC in English grammar, and PEMDAS in mathematics. It
1397-650: A full appearance in The Wedding of Sarah Jane Smith (2009), in which the Doctor briefly welcomes Sarah Jane's three adolescent companions into the control room. It then serves as a backdrop for the farewell scene between Sarah Jane and the Tenth Doctor, which echoed nearly word-for-word her final exchange with the Fourth Doctor aboard the TARDIS in 1976. It reappears in Death of the Doctor (2010), where it

The Doctor has attempted to repair the chameleon circuit, unsuccessfully in Logopolis (1981) and with only temporary success in Attack of the Cybermen (1985). In the 2005 television story " Boom Town ", the Doctor reveals that he has stopped trying to repair
1778-781: A medial decimal point . Particularly in British and Commonwealth English , all such punctuation marking acronyms and other capitalized abbreviations is now uncommon and considered either unnecessary or incorrect. The presence of all-capital letters is now thought sufficient to indicate the nature of the UK , the EU , and the UN . Forms such as the U.S.A. for "the United States of America " are now considered to indicate American or North American English . Even within those dialects, such punctuation
1905-473: A mixed reaction to the serial, according to the BBC's Audience Research Report, but there had been a majority of "moderate approval". Howe and Walker themselves commended the "very well written and highly intelligent" scripts, the "polished production", and strong cast. In 2010, Patrick Mulkern of Radio Times described the serial as "polished" with "an air of confidence in the writing and performances". He praised
2032-400: A move to a more steampunk -inspired set design, which later influenced the set design in the revived series from 2005 onwards . The production team conceived of the TARDIS travelling by dematerialising at one point and rematerialising elsewhere, although sometimes in the series it is shown also to be capable of conventional space travel. In the 2006 Christmas special, " The Runaway Bride ",
2159-459: A new religion. The Doctor tells Giuliano the temple must be destroyed. They go to the temple, and the Doctor enters the catacombs alone. Giuliano tells Sarah that he and a few others believe that the earth is a sphere ( although that was common knowledge of the day ). As the Doctor enters the main chamber the Helix attacks him psychically. Rossini informs Federico of Giuliano's trip to the temple, and
2286-603: A novelty pop single in 1988 entitled " Doctorin' the Tardis ". The record reached number one in the UK Singles Chart and had chart success worldwide. It was a reworking of several songs (principally Gary Glitter 's " Rock and Roll Part 2 ", The Sweet 's " Block Buster! " and the Doctor Who theme music ) with lyrics referencing Doctor Who , specifically the TARDIS. In 2007, the British rock band Radiohead included
2413-529: A peasant revolt is violently put down by Count Federico and his men, led by Captain Rossini. In a palace, Federico's brother, the Duke of San Martino, lies dying, attended to by his son Giuliano and Giuliano's companion Marco. The Duke's death had been foretold by Hieronymous, the court astrologer , but Giuliano, a man of science, does not believe in such superstition. In fact, Hieronymous is working for Federico, and
2540-407: A period when the letters are pronounced individually, as in " K.G.B. ", but not when pronounced as a word, as in " NATO ". The logic of this style is that the pronunciation is reflected graphically by the punctuation scheme. When a multiple-letter abbreviation is formed from a single word, periods are in general not used, although they may be common in informal usage. "TV", for example, may stand for

After the Helix vanishes, the figure removes his mask, revealing the face of Hieronymous. The guards take the Doctor and Sarah to Giuliano, who shows him the dead guard's body and tells the Doctor of fears that if Federico rules San Martino, all knowledge and learning will be suppressed. Elsewhere, Federico discovers that Giuliano has invited several nobles to San Martino to celebrate his succession to

At the palace, the invited nobles arrive and Federico realizes he does not have much time to eliminate Giuliano, but Rossini is unable to find Giuliano. Hieronymous warns Federico that his life is in danger. Federico scoffs, believing Hieronymous a fraud, but is suspicious enough to tell Rossini to banish Hieronymous from the city. In the catacombs, Giuliano and

The Chicago Manual of Style acknowledges the complexity ("Furthermore, an acronym and initialism are occasionally combined (JPEG), and the line between initialism and acronym is not always clear") but still defines
3429-527: A time rotor. The presence of a physically larger space contained within the police box is explained as "dimensionally transcendental", with the interior being a whole separate dimension containing an infinite number of rooms, corridors and storage spaces, all of which can change their appearance and configuration. The TARDIS also allows the Doctor and others to communicate with people who speak languages other than their own, as well as turn all written languages to English. The "translation circuit" (occasionally called
3556-515: A twentieth-century phenomenon. Linguist David Wilton in Word Myths: Debunking Linguistic Urban Legends claims that "forming words from acronyms is a distinctly twentieth- (and now twenty-first-) century phenomenon. There is only one known pre-twentieth-century [English] word with an acronymic origin and it was in vogue for only a short time in 1886. The word is colinderies or colinda , an acronym for
3683-471: A word, an abbreviation is not an acronym." In contrast, some style guides do support it, whether explicitly or implicitly. The 1994 edition of Merriam-Webster's Dictionary of English Usage defends the usage on the basis of a claim that dictionaries do not make a distinction. The BuzzFeed style guide describes CBS and PBS as "acronyms ending in S". Acronymy, like retronymy , is a linguistic process that has existed throughout history but for which there
3810-677: A word. American English dictionaries such as Merriam-Webster , Dictionary.com's Random House Webster's Unabridged Dictionary and the American Heritage Dictionary as well as the British Oxford English Dictionary and the Australian Macquarie Dictionary all include a sense in their entries for acronym equating it with initialism , although The American Heritage Dictionary criticizes it with
3937-572: Is a subset with a narrower definition: an initialism pronounced as a word rather than as a sequence of letters. In this sense, NASA / ˈ n æ s ə / is an acronym but USA / j uː ɛ s ˈ eɪ / is not. The broader sense of acronym , ignoring pronunciation, is its original meaning and in common use. Dictionary and style-guide editors dispute whether the term acronym can be legitimately applied to abbreviations which are not pronounced as words, and they do not agree on acronym spacing , casing , and punctuation . The phrase that

4064-488: Is a question about how to pluralize acronyms. Often a writer will add an 's' following an apostrophe, as in "PC's". However, Kate L. Turabian 's A Manual for Writers of Research Papers, Theses, and Dissertations , writing about style in academic writings, allows for an apostrophe to form plural acronyms "only when an abbreviation contains internal periods or both capital and lowercase letters". Turabian would therefore prefer "DVDs" and "URLs" but "Ph.D.'s". The style guides of

Federico orders the Doctor to be executed as a spy. Meanwhile, Sarah is brought before a priest and told that she is the foretold sacrifice to Demnos, the Roman god of moonlight and solstice. In the palace courtyard, the Doctor is led to the executioner. Before

Larry Trask , American author of The Penguin Guide to Punctuation , states categorically that, in British English , "this tiresome and unnecessary practice is now obsolete." Nevertheless, some influential style guides , many of them American , still require periods in certain instances. For example, The New York Times Manual of Style and Usage recommends following each segment with

The complete 2005 season DVD box set, released in November 2005, was issued in packaging that resembled the TARDIS. One of the original-model TARDISes used in the television series' production in the 1970s was sold at auction in December 2005 for £ 10,800.

It also gives students a convenient review list to memorize the important acronyms introduced in a textbook chapter. Expansion at first use and abbreviation keys originated in the print era, but they are equally useful for electronic text . While acronyms provide convenience and succinctness for specialists, they often degenerate into confusing jargon . This may be intentional, to exclude readers without domain-specific knowledge. New acronyms may also confuse when they coincide with an already existing acronym having

The Count at first thinks the Doctor
5080-459: Is not uncommon for acronyms to be cited in a kind of false etymology , called a folk etymology , for a word. Such etymologies persist in popular culture but have no factual basis in historical linguistics , and are examples of language-related urban legends . For example, " cop " is commonly cited as being derived, it is presumed, from "constable on patrol", and " posh " from " port outward, starboard home ". With some of these specious expansions,

However, although acronymic words seem not to have been employed in general vocabulary before the twentieth century (as Wilton points out), the concept of their formation is treated as effortlessly understood (and evidently not novel) in an Edgar Allan Poe story of the 1830s, " How to Write a Blackwood Article ", which includes
5969-623: The Modern Language Association and American Psychological Association prohibit apostrophes from being used to pluralize acronyms regardless of periods (so "compact discs" would be "CDs" or "C.D.s"), whereas The New York Times Manual of Style and Usage requires an apostrophe when pluralizing all abbreviations regardless of periods (preferring "PC's, TV's and VCR's"). Possessive plurals that also include apostrophes for mere pluralization and periods appear especially complex: for example, "the C.D.'s' labels" (the labels of

9398-409: The TARDIS police box props used in the series have changed many times, as a result of damage and the requirements of the show, and none of the BBC props has been a faithful replica of the original MacKenzie Trench model. Numerous details have been altered over time, including the shape of the roof, the signage, the shade of blue paint, the presence of a St John Ambulance emblem and the overall height of
9525-579: The TARDIS should automatically adopt a disguise, such as a howdah (a carrier on the back of an Indian elephant in the Indian Mutiny ) or a rock on a beach. Accounts differ as to the origin of the police box prop. While the BBC asserts that it was constructed specially for Doctor Who , it has been claimed that the box was a reused prop from the BBC television police dramas Z-Cars or Dixon of Dock Green (a claim later repeated by Doctor Who producer Steven Moffat ). The dimensions and colour of
9652-560: The TARDIS, issued on Niue Island in the South Pacific Ocean by the Perth Mint to mark the 50th anniversary of the Doctor Who television show; and Tardis Environmental, a British sewage company, in reference to the similarity of their portable toilets to a police box. "Tardis" has also become a slang term used in the British real estate industry, to suggest that a house or apartment is actually substantally bigger on
9779-564: The U.S. Navy, is "COMCRUDESPAC", which stands for "commander, cruisers destroyers Pacific"; it is also seen as "ComCruDesPac". Inventors are encouraged to anticipate the formation of acronyms by making new terms "YABA-compatible" ("yet another bloody acronym"), meaning the term's acronym can be pronounced and is not an offensive word: "When choosing a new name, be sure it is 'YABA-compatible'." Acronym use has been further popularized by text messaging on mobile phones with short message service (SMS), and instant messenger (IM). To fit messages into
9906-560: The United States are among the " alphabet agencies " (jokingly referred to as " alphabet soup ") created under the New Deal by Franklin D. Roosevelt (himself known as "FDR"). Business and industry also coin acronyms prolifically. The rapid advance of science and technology also drives the usage, as new inventions and concepts with multiword names create a demand for shorter, more pronounceable names. One representative example, from
10033-411: The acronym may use normal case rules, e.g. it would appear generally in lower case, but with an initial capital when starting a sentence or when in a title. Once knowledge of the words underlying such an acronym has faded from common recall, the acronym may be termed an anacronym . Examples of anacronyms are the words " scuba ", " radar ", and " laser ". The word "an acro nym" should not be confused with
10160-545: The acronym stands for is called its expansion . The meaning of an acronym includes both its expansion and the meaning of its expansion. The word acronym is formed from the Greek roots akro- , meaning 'height, summit, or tip', and -nym , 'name'. This neoclassical compound appears to have originated in German , with attestations for the German form Akronym appearing as early as 1921. Citations in English date to
10287-590: The adoption of acronyms was modern warfare, with its many highly technical terms. While there is no recorded use of military acronyms dating from the American Civil War (acronyms such as "ANV" for " Army of Northern Virginia " post-date the war itself), they became somewhat common in World War I , and by World War II they were widespread even in the slang of soldiers, who referred to themselves as G.I.s . The widespread, frequent use of acronyms across
10414-506: The apostrophe should be reserved for the possessive ("the TV's antenna"). In some languages, the convention of doubling the letters in the acronym is used to indicate plural words: for example, the Spanish EE.UU. , for Estados Unidos ('United States'). This old convention is still sometimes followed for a limited number of English abbreviations, such as SS. for Saints , pp. for
10541-405: The box. The original prop remained in use for around 13 years until it collapsed – reportedly on Elisabeth Sladen 's head. A new prop was introduced for The Masque of Mandragora in 1976, and there have been at least six versions in total. The evolution of the prop design was referenced on-screen in the episode " Blink " (2007), when the character Detective Inspector Shipton says the TARDIS "isn't
10668-1163: The case. Sometimes function words are included to make a pronounceable acronym, such as CORE ( Congress of Racial Equality ). Sometimes the letters representing these words are written in lower case, such as in the cases of "TfL" (" Transport for London ") and LotR ( The Lord of the Rings ); this usually occurs when the acronym represents a multi-word proper noun. Numbers (both cardinal and ordinal ) in names are often represented by digits rather than initial letters, as in "4GL" (" fourth generation language ") or "G77" (" Group of 77 "). Large numbers may use metric prefixes , as with " Y2K " for "Year 2000". Exceptions using initials for numbers include " TLA " ("three-letter acronym/abbreviation") and "GoF" (" Gang of Four "). Abbreviations using numbers for other purposes include repetitions, such as " A2DP " ("Advanced Audio Distribution Profile"), " W3C " ("World Wide Web Consortium"), and T3 ( Trends, Tips & Tools for Everyday Living ); pronunciation, such as " B2B " ("business to business"); and numeronyms , such as "i18n" ("internationalization"; "18" represents
10795-460: The catacombs. Sarah is brought back to the astrologer's chambers where she is left gagged as the Priest and Hieronymous talk. The priest is eager to sacrifice Sarah, but Hieronymous decides to use her as bait for the Doctor. Hieronymous allowed the Brethren to save Giuliano because the young prince may still have value. Sarah is hypnotised to believe the Doctor is an evil sorcerer. Hieronymous gives her
10922-453: The central console and to the layout, but the overall concept remained constant. In Season 14 (1976–77), a dark wood-panelled "Control Room Number 2" was briefly used for a few episodes, but the white console room set was reinstated in Season 15 , due to damage to the set. After the cancellation of the television show, a radically redesigned TARDIS set was used in the 1996 TV movie , heralding
11049-416: The circuit as he has become fond of its appearance. The other TARDISes that appear in the series have chameleon circuits that are fully functional. While the exterior is of limited size, the TARDIS is famously "bigger on the inside". Behind the police box doors lies a large control room, at the centre of which is a console for operating the TARDIS. In the middle of the console is a moving tubular device called
11176-413: The compact discs). In some instances, however, an apostrophe may increase clarity: for example, if the final letter of an abbreviation is "S", as in "SOS's" (although abbreviations ending with S can also take "-es", e.g. "SOSes"), or when pluralizing an abbreviation that has periods. A particularly rich source of options arises when the plural of an acronym would normally be indicated in a word other than
11303-564: The contrived acronym "P.R.E.T.T.Y.B.L.U.E.B.A.T.C.H." The use of Latin and Neo-Latin terms in vernaculars has been pan-European and pre-dates modern English. Some examples of acronyms in this class are: The earliest example of a word derived from an acronym listed by the OED is "abjud" (now " abjad "), formed from the original first four letters of the Arabic alphabet in the late eighteenth century. Some acrostics pre-date this, however, such as
11430-438: The dictionary entries and style guide recommendations regarding the term acronym through the twentieth century did not explicitly acknowledge or support the expansive sense. The Merriam–Webster's Dictionary of English Usage from 1994 is one of the earliest publications to advocate for the expansive sense, and all the major dictionary editions that include a sense of acronym equating it with initialism were first published in
11557-835: The end of the 20th century. Working titles for this story included The Catacombs of Death and The Curse of Mandragora . The ultimate name references the masque, entertainment performed by masked players, that later plays a key role in the plot. Location shooting for the serial was done at the resort of Portmeirion in Wales, better known as the setting for the cult series The Prisoner . Tim Pigott-Smith previously played Captain Harker in The Claws of Axos (1971). Norman Jones previously played Khrisong in The Abominable Snowmen (1967) and Major Baker in Doctor Who and
11684-664: The exclusive sense for acronym and its earliest citation was from 1943. In early December 2010, Duke University researcher Stephen Goranson published a citation for acronym to the American Dialect Society e-mail discussion list which refers to PGN being pronounced "pee-gee-enn", antedating English language usage of the word to 1940. Linguist Ben Zimmer then mentioned this citation in his December 16, 2010 " On Language " column about acronyms in The New York Times Magazine . By 2011,
11811-408: The executioner's sword lands, the Doctor unfurls his scarf and hooks it around the executioner's ankle, throwing him off balance. The Doctor escapes and finds his way into catacombs beneath the city. The guards, fearing the Brethren of Demnos who reside there, stop their pursuit. Inside, Sarah is laid out on an altar. A purple-robed figure is about to stab her when the Doctor snatches Sarah away, just as
11938-544: The fade-in and fade-out effects of a TARDIS. Writer Patrick Ness has described the ship's distinctive dematerialisation noise as "a kind of haunted grinding sound", while the Doctor Who Magazine comic strips traditionally use the onomatopoeic phrase "vworp vworp vworp". The sound of the Doctor's TARDIS featured in the final scene of the Torchwood episode " End of Days " (2007). As Torchwood Three's hub
12065-763: The final word if spelled out in full. A classic example is "Member of Parliament", which in plural is "Members of Parliament". It is possible then to abbreviate this as "M's P", which was fairly common in mid-twentieth-century Australian news writing (or similar ), and used by former Australian Prime Minister Ben Chifley . This usage is less common than forms with "s" at the end, such as "MPs", and may appear dated or pedantic. In common usage, therefore, "weapons of mass destruction" becomes "WMDs", "prisoners of war" becomes "POWs", and "runs batted in" becomes "RBIs". Abbreviations that come from single, rather than multiple, words – such as "TV" ("television") – are usually pluralized without apostrophes ("two TVs"); most writers feel that
12192-464: The first letter of acronyms, reserving all-caps styling for initialisms, writing the pronounced acronyms "Nato" and "Aids" in mixed case, but the initialisms "USA" and "FBI" in all caps. For example, this is the style used in The Guardian , and BBC News typically edits to this style (though its official style guide, dating from 2003, still recommends all-caps ). The logic of this style is that
12319-405: The fragment appears in the chamber, suffusing it with a red glow and providing a distraction for the two to escape. Giuliano examines the body of a guard who was killed earlier by the fragment, and while he does not know the cause of the guard's death, he dismisses ideas that it was some kind of fire demon. The Doctor and Sarah are found by palace guards. In the temple, the Helix manifests itself as
12446-538: The gameplay of a number of popular video games , including Lego Dimensions and Fortnite: Battle Royale . To promote the Barbie film released in July 2023, a pink TARDIS was unveiled next to Tower Bridge in London on 11 July, as Ncuti Gatwa would appear in both Barbie as a Ken and in Doctor Who as the Fifteenth Doctor . Other references to the TARDIS have included a $ 2 silver commemorative coin depicting
12573-473: The guards but does not seem to have seen the Doctor. The Doctor joins the circle around the Helix as Hieronymous announces that Mandragora will swallow the moon the next evening and then the Brethren will strike. The Doctor slips away unnoticed. In the palace dungeons, Rossini is about to kill the prisoners when the Doctor arrives and reveals that Federico is dead. The guards change their allegiance to Giuliano and take Rossini into custody. The Doctor observes that
12700-424: The guards capture the Doctor, Sarah, and Giuliano. In the dungeons, Federico accuses the prisoners of being followers of Demnos. Rossini rushes in, informing the Count that members of the Brethren are moving towards the temple. The Doctor tries to convince Federico that Hieronymous is the real threat. Federico takes the Doctor with him and some guards, leaving the others as hostages. In the temple, Hieronymous summons
12827-421: The horoscope's prediction of the Duke's death was helped along by poison. Hieronymous tells the Count that he feels his powers are growing, but all Federico wants is for the astrologer to foretell Giuliano's death next, and he will take care of the rest. The TARDIS materialises in a field near San Martino, and when the Doctor and Sarah exit, the energy fragment flies out of the TARDIS, unseen. Sarah wanders off and
12954-414: The inception of the show in 1963 up until the end of the " classic series " in 1989, the design of the TARDIS console room remained largely unchanged from Brachacki's original set, a brightly lit white chamber, lined with a pattern of roundels on the walls and with a central hexagonal console which contained a cylindrical "time rotor" that moved when the TARDIS was in transit. Numerous alterations were made to
13081-429: The inside that it looks on the outside. Acronym An acronym is a type of abbreviation consisting of a phrase whose only pronounced elements are the initial letters or initial sounds of words inside that phrase. Acronyms are often spelled with the initial letter of each word in all caps with no punctuation . For some, an initialism or alphabetism , connotes this general meaning, and an acronym
13208-435: The king". In English, abbreviations have previously been marked by a wide variety of punctuation . Obsolete forms include using an overbar or colon to show the ellipsis of letters following the initial part. The forward slash is still common in many dialects for some fixed expressions—such as in w/ for "with" or A/C for " air conditioning "—while only infrequently being used to abbreviate new terms. The apostrophe
13335-500: The label "usage problem". However, many English language dictionaries, such as the Collins COBUILD Advanced Dictionary , Cambridge Advanced Learner's Dictionary , Macmillan Dictionary , Longman Dictionary of Contemporary English , New Oxford American Dictionary , Webster's New World Dictionary , and Lexico from Oxford University Press do not acknowledge such a sense. Most of
13462-836: The language to changing circumstances. In this view, the modern practice is just the "proper" English of the current generation of speakers, much like the earlier abbreviation of corporation names on ticker tape or newspapers. Exact pronunciation of "word acronyms" (those pronounced as words rather than sounded out as individual letters) often vary by speaker population. These may be regional, occupational, or generational differences, or simply personal preference. For instance, there have been decades of online debate about how to pronounce GIF ( / ɡ ɪ f / or / dʒ ɪ f / ) and BIOS ( / ˈ b aɪ oʊ s / , / ˈ b aɪ oʊ z / , or / ˈ b aɪ ɒ s / ). Similarly, some letter-by-letter initialisms may become word acronyms over time, especially in combining forms: IP for Internet Protocol
13589-498: The line was plural in the script for the episode). The acronym was explained in the first episode of the show, An Unearthly Child (1963), in which the Doctor's granddaughter Susan claims to have made it up herself. Despite this, the term is used commonly by other Time Lords to refer to both the Doctor's and their own time ships. Generally, "TARDIS" is written in all uppercase letters , but may also be written in title case as "Tardis". The word "Tardis" first appeared in print in
13716-413: The masked ball ending and the costumes and music, and remarked that "perhaps the only feeble note is the representation of the Helix". DVD Talk 's Ian Jane gave The Masque of Mandragora three and a half out of five stars, calling it "pretty entertaining stuff". While he felt that "it's a bit predictable and most of the supporting cast is surprisingly poorly defined", he praised Baker and the atmosphere of
13843-495: The middle of sentences for proper nouns; when following the AMA Manual of Style , this would instead be rendered as "the onset of congestive heart failure (CHF)". The Masque of Mandragora The Masque of Mandragora is the first serial of the 14th season of the British science fiction television series Doctor Who , which was first broadcast in four weekly parts on BBC1 from 4 to 25 September 1976. The serial
13970-466: The more general "x" can be used to replace an unspecified number of letters. Examples include "Crxn" for "crystallization" and the series familiar to physicians for history , diagnosis , and treatment ("hx", "dx", "tx"). Terms relating to a command structure may also sometimes use this formatting, for example gold, silver, and bronze levels of command in UK policing being referred to as Gx, Sx, and Bx. There
14097-609: The nature of the supernatural world." Paul Cornell , Martin Day , and Keith Topping wrote of the serial in The Discontinuity Guide (1995), "One of the few metaphors in Doctor Who history (nasty alien energy mass = superstition and scientific ignorance) is blurred by the lack of actual scientific understanding that the story exhibits. Looks and sounds great, though." In The Television Companion (1998), David J. Howe and Stephen James Walker reported that viewers had
14224-729: The plural of 'pages', or mss. for manuscripts . The most common capitalization scheme seen with acronyms is all-uppercase ( all caps ). Small caps are sometimes used to make the run of capital letters seem less jarring to the reader. For example, the style of some American publications, including the Atlantic Monthly and USA Today , is to use small caps for acronyms longer than three letters; thus "U.S." and " FDR " in normal caps, but " nato " in small caps. The acronyms " AD " and " BC " are often smallcapped as well, as in: "From 4004 bc to ad 525 ". Where an acronym has linguistically taken on an identity as regular word,
14351-544: The police. The Patent Office issued a ruling in favour of the BBC in 2002. The word TARDIS is listed in the Oxford English Dictionary . A number of legacy police boxes are still standing on streets around the United Kingdom. Although now no longer used for their original function, many have been repurposed as coffee kiosks, and are often affectionately referred to as TARDISes. A police box in
14478-483: The pronunciation is reflected graphically by the capitalization scheme. However, it conflicts with conventional English usage of first-letter upper-casing as a marker of proper names in many cases; e.g. AIDS stands for acquired immuno-deficiency syndrome which is not a proper name, while Aids is in the style of one. Some style manuals also base the letters' case on their number. The New York Times , for example, keeps "NATO" in all capitals (while several guides in
14605-685: The publication of the 3rd edition of the Oxford English Dictionary added the expansive sense to its entry for acronym and included the 1940 citation. As the Oxford English Dictionary structures the senses in order of chronological development, it now gives the "initialism" sense first. English language usage and style guides which have entries for acronym generally criticize the usage that refers to forms that are not pronounceable words. Fowler's Dictionary of Modern English Usage says that acronym "denotes abbreviations formed from initial letters of other words and pronounced as
14732-523: The science of translation technology, Doctor Who gets it wrong more often than it gets it right. However, perhaps we can forgive the artistic license if we recognise that, as in other science fiction works, the presentation of some type of ubiquitous translation tool is necessary to explain to the audience how people from other countries, time periods, and even other worlds, can understand each other and indeed appear to speak (mostly) flawless English." The TARDIS also has other special abilities: it can produce
14859-542: The serial and wrote that ultimately the good outweighs the bad. A novelisation of this serial, written by Philip Hinchcliffe , was published by Target Books in December 1977. A French translation of it was published in 1987. An unabridged reading of the novelisation read by Tim Pigott-Smith was released by BBC Audiobooks in April 2009. This story was released on VHS in August 1991, on DVD on 8 February 2010, and as part of
14986-470: The sides of railroad cars (e.g., "Richmond, Fredericksburg and Potomac Railroad" → "RF&P"); on the sides of barrels and crates; and on ticker tape and newspaper stock listings (e.g. American Telephone and Telegraph Company → AT&T). Some well-known commercial examples dating from the 1890s through 1920s include " Nabisco " ("National Biscuit Company"), " Esso " (from "S.O.", from " Standard Oil "), and " Sunoco " ("Sun Oil Company"). Another field for
15113-456: The song "Up on the Ladder" on their album In Rainbows which begins with the line "I'm stuck in the TARDIS". In 2001, Turner Prize -winning artist Mark Wallinger created a piece or artwork entitled Time and Relative Dimensions in Space that is structurally a police box shape faced with mirrors. The BBC website describes it as "recent proof of [the TARDIS'] enduring legacy". In July 2014,
15240-476: The term acronym only for forms pronounced as a word, and using initialism or abbreviation for those that are not. Some sources acknowledge the usage, but vary in whether they criticize or forbid it, allow it without comment, or explicitly advocate it. Some mainstream English dictionaries from across the English-speaking world affirm a sense of acronym which does not require being pronounced as
15367-502: The terms as mutually exclusive. Other guides outright deny any legitimacy to the usage: Bryson's Dictionary of Troublesome Words says "Abbreviations that are not pronounced as words (IBM, ABC, NFL) are not acronyms; they are just abbreviations." Garner's Modern American Usage says "An acronym is made from the first letters or parts of a compound term. It's read or spoken as a single word, not letter by letter." The New York Times Manual of Style and Usage says "Unless pronounced as
15494-493: The twenty-first century. The trend among dictionary editors appears to be towards including a sense defining acronym as initialism : the Merriam-Webster's Collegiate Dictionary added such a sense in its 11th edition in 2003, and both the Oxford English Dictionary and The American Heritage Dictionary added such senses in their 2011 editions. The 1989 edition of the Oxford English Dictionary only included
15621-536: The whole range of linguistic registers is relatively new in most languages, becoming increasingly evident since the mid-twentieth century. As literacy spread and technology produced a constant stream of new and complex terms, abbreviations became increasingly convenient. The Oxford English Dictionary ( OED ) records the first printed use of the word initialism as occurring in 1899, but it did not come into general use until 1965, well after acronym had become common. In English, acronyms pronounced as words may be
15748-425: The word " an achro nym ", which is a type of misnomer. Words derived from an acronym by affixing are typically expressed in mixed case, so the root acronym is clear. For example, "pre-WWII politics", "post-NATO world", " DNase ". In some cases a derived acronym may also be expressed in mixed case. For example, " messenger RNA " and " transfer RNA " become "mRNA" and "tRNA". Some publications choose to capitalize only
15875-511: Was done with a full space between every full word (e.g. A. D. , i. e. , and e. g. for " Anno Domini ", " id est ", and " exempli gratia "). This even included punctuation after both Roman and Arabic numerals to indicate their use in place of the full names of each number (e.g. LII. or 52. in place of "fifty-two" and "1/4." or "1./4." to indicate "one-fourth"). Both conventions have fallen out of common use in all dialects of English, except in places where an Arabic decimal includes
16002-449: Was little to no naming , conscious attention, or systematic analysis until relatively recent times. Like retronymy, it became much more common in the twentieth century than it had formerly been. Ancient examples of acronymy (before the term "acronym" was invented) include the following: During the mid- to late nineteenth century, acronyms became a trend among American and European businessmen: abbreviating corporation names, such as on
16129-399: Was once commonly seen on streets in Britain in the 1940s and 50s. Paradoxically, its interior is shown as being much larger than its exterior, commonly described as being "bigger on the inside". Due to the significance of Doctor Who in popular British culture , the shape of the police box is now more strongly associated with the TARDIS than its real-world inspiration. The name and design of
