The '''glottal stop''' or '''glottal plosive''' is a type of [[consonant]]al sound used in many [[Speech communication|spoken]] [[language]]s, produced by obstructing airflow in the vocal tract or, more precisely, the [[glottis]]. The symbol in the [[International Phonetic Alphabet]] that represents this sound is {{angbr IPA|ʔ}}.

As a result of the obstruction of the airflow in the glottis, the glottal vibration either stops or becomes irregular with a low rate and sudden drop in intensity.<ref name="umeda">{{Cite journal |last=Umeda |first=Noriko |date=1978 |title=Occurrence of Glottal Stops in Fluent Speech |journal=The Journal of the Acoustical Society of America |language=en |volume=64 |issue=1 |pages=88–94 |doi=10.1121/1.381959|pmid=712005 |bibcode=1978ASAJ...64...88U }}</ref>

In the traditional [[romanization]] of many languages, such as Arabic, the glottal stop is transcribed with the [[Modifier letter apostrophe|apostrophe]] [[ʼ|{{angle bracket|ʼ}}]] or the symbol [[ʾ|{{angbr|ʾ}}]], which is the source of the IPA character {{angbr IPA|ʔ}}. In many [[Polynesian languages]] that use the [[Latin alphabet]], however, the glottal stop is written with a rotated apostrophe, {{angbr|{{okina}}}} (called ''[[ʻokina]]'' in [[Hawaiian language|Hawaiian]] and [[Samoan language|Samoan]]), which is commonly used to transcribe the Arabic [[ayin]] as well (also {{angbr|{{ayin}}}}) and is the source of the IPA character for the [[voiced pharyngeal fricative]] {{angbr IPA|ʕ}}. In [[Malay language|Malay]] the glottal stop is represented by the letter {{angbr|k}} (at the end of words), in [[Võro language|Võro]] and [[Maltese language|Maltese]] by {{angbr|q}}. Another way of writing the glottal stop is the [[Saltillo (linguistics)#The saltillo letter|saltillo]] {{Angbr|Ꞌ ꞌ}}, used in languages such as [[Tlapanec language|Tlapanec]] and [[Rapa Nui language|Rapa Nui]].

Other scripts also have letters used for representing the glottal stop, such as the [[Hebrew alphabet|Hebrew letter]] [[aleph]] {{angbr|{{Script/Hebrew|א}}}} and the [[Cyrillic script|Cyrillic]] letter [[palochka]] {{angbr|Ӏ}}, used in several [[Languages of the Caucasus|Caucasian languages]]. The [[Arabic script]] uses [[hamza]] {{angbr|{{lang|ar|ء}}}}, which can appear both as a [[diacritic]] and as an independent letter (though not part of the alphabet). In [[Tundra Nenets language|Tundra Nenets]], it is represented by the letters [[modifier letter apostrophe|apostrophe]] {{angbr|ʼ}} and [[modifier letter double apostrophe|double apostrophe]] {{angbr|ˮ}}. In [[Japanese language|Japanese]], glottal stops occur at the end of interjections of surprise or anger and are represented by the character {{angbr|[[っ]]}}.

In the graphic representation of most [[Philippine languages]], the glottal stop has no consistent symbolization. In most cases, however, a word that begins with a vowel-letter (e.g. [[Tagalog language|Tagalog]] {{lang|tl|aso}}, "dog") is always pronounced with an unrepresented glottal stop before that vowel (as in Modern [[German language|German]] and [[Hausa language|Hausa]]). Some orthographies use a hyphen instead of the reverse apostrophe if the glottal stop occurs in the middle of the word (e.g. Tagalog {{lang|tl|pag-ibig}}, "love"; or [[Visayan languages|Visayan]] ''gabi-i'', "night"). If it occurs in the end of a word, the last vowel can be written with a [[circumflex accent]] (known as the ''pakupyâ'') if both a stress and a glottal stop occur in the final vowel (e.g. ''basâ'', "wet") or a [[grave accent]] (known as the ''paiwà'') if the glottal stop occurs at the final vowel, but the stress occurs at the penultimate syllable (e.g. ''batà'', "child").<ref name="expr">{{Cite web |last=Morrow |first=Paul |date=March 16, 2011 |title=The Basics of Filipino Pronunciation: Part 2 of 3 • Accent Marks |url=https://www.pilipino-express.com/history-a-culture/in-other-words/1180-basics-of-filipino-pronunciation-part-2.html |url-status=live |archive-url=https://web.archive.org/web/20111227075213/https://www.pilipino-express.com/history-a-culture/in-other-words/1180-basics-of-filipino-pronunciation-part-2.html |archive-date=December 27, 2011 |access-date=July 18, 2012 |website=Pilipino Express |language=en}}</ref><ref name="nolasco">{{Citation |last=Nolasco |first=Ricardo M.

Some [[Languages of Canada#Indigenous languages|Canadian indigenous languages]], especially some of the [[Salishan languages]], have adopted the IPA letter {{angbr|ʔ}} into their orthographies. In some of them, it occurs as a [[casing pair]], [[glottal stop (letter)|{{angbr|Ɂ}} and {{angbr|ɂ}}]].<ref>{{Citation |title=Proposal to Add Latin Small Letter Glottal Stop to the UCS |date=2005-08-10 |url=https://std.dkuug.dk/jtc1/sc2/wg2/docs/n2962.pdf |postscript=. |archive-url=https://web.archive.org/web/20110926214035/https://std.dkuug.dk/jtc1/sc2/wg2/docs/n2962.pdf |language=en |access-date=2011-10-26 |archive-date=2011-09-26 |url-status=live}}</ref> The digit {{angbr|7}} or a [[question mark]] is sometimes substituted for {{angbr|ʔ}}, and is preferred in languages such as [[Squamish language|Squamish]].

In 2015, two women in the [[Northwest Territories]] challenged the territorial government over its refusal to permit them to use the letter {{angbr|ʔ}} in their daughters' names: ''Sahaiʔa'', a [[Chipewyan language|Chipewyan]] name, and ''Sakaeʔah'', a [[Slavey language|Slavey]] name (the two names are actually [[cognate]]s). The territory argued that territorial and federal identity documents were unable to accommodate the character. The women registered the names with hyphens instead of the {{angbr|ʔ}}, while continuing to challenge the policy.<ref>{{Cite web |last=Browne |first=Rachel |date=12 March 2015 |title=What's in A Name? a Chipewyan's Battle Over Her Native Tongue |url=https://www.macleans.ca/society/life/all-in-the-family-name/ |url-status=live |archive-url=https://web.archive.org/web/20150404142237/https://www.macleans.ca/society/life/all-in-the-family-name/ |archive-date=4 April 2015 |access-date=5 April 2015 |website=Maclean's |language=en}}</ref>

In the [[Crow language]], the glottal stop is written as a [[question mark]] {{angbr|?}}. The only instance of the glottal stop in Crow is as a [[question marker]] morpheme at the end of a sentence.<ref>{{Cite book |last=Graczyk |first=Randolph |title=A grammar of Crow = Apsáalooke Aliláau |date=2007 |publisher=University of Nebraska Press |others=Bloomington.

Use of the glottal stop is a distinct characteristic of the Southern Mainland [[Argyll]] dialects of [[Scottish Gaelic]]. In such a dialect, the standard Gaelic phrase {{lang|gd|Tha Gàidhlig agam}} ("I speak Gaelic"), would be rendered {{lang|gd|Tha Gàidhlig a'am}}.{{citation needed|date=July 2012}}

In the [[Nawdm language]] of Ghana, the glottal stop is written ''ɦ'', capital ''Ĥ''.

==In English==
===Replacement of /t/===
In English, the glottal stop occurs as an [[open juncture]] (for example, between the vowel sounds in ''uh-oh!'',<ref>{{Cite book |url=https://books.google.com/books?id=ooR_9bUYwR8C&pg=PR28 |title=Mastering Hebrew |date=1988 |publisher=Barron's |isbn=0-8120-3990-4 |language=en |access-date=2016-11-26 |archive-date=2020-08-01 |archive-url=https://web.archive.org/web/20200801230122/https://books.google.com/books?id=ooR_9bUYwR8C&pg=PR28 |url-status=live }}</ref>) and allophonically in [[t-glottalization]].  In [[British English]], the glottal stop is most familiar in the [[Cockney]] pronunciation of "butter" as "bu'er". [[Geordie]] English often uses glottal stops for t, k, and p, and has a unique form of glottalization. Additionally, there is the glottal stop as a [[Syllable#Null onset|null onset]] for English; in other words, it is the non-phonemic glottal stop occurring before isolated or initial vowels.

Often a glottal stop happens at the beginning of vowel [[phonation]] after a silence.<ref name = umeda/>

Although this [[segment (linguistics)|segment]] is not a [[phoneme]] in English, it occurs phonetically in nearly all dialects of English, as an [[allophone]] of {{IPA|/t/}} in the syllable coda. Speakers of Cockney, [[Scottish English]] and several other British dialects also pronounce an intervocalic {{IPA|/t/}} between vowels as in ''city''. In [[Received Pronunciation]], a glottal stop is inserted before a [[tautosyllabic]] voiceless stop: sto{{hamza}}p, tha{{hamza}}t, kno{{hamza}}ck, wa{{hamza}}tch, also lea{{hamza}}p, soa{{hamza}}k, hel{{hamza}}p, pin{{hamza}}ch.<ref>{{Cite book |last=Brown |first=Gillian |title=Listening to Spoken English |date=1977 |publisher=Longman |location=London |page=27 |language=en}}</ref><ref name="Kortlandt">{{Citation |last=Kortlandt |first=Frederik |title=General Linguistics & Indo-European Reconstruction |date=1993 |url=https://www.kortlandt.nl/publications/art130e.pdf |postscript=. |archive-url=https://web.archive.org/web/20110608062414/https://www.kortlandt.nl/publications/art130e.pdf |language=en |access-date=2009-08-23 |archive-date=2011-06-08 |author-link=Frederik Kortlandt |via=kortlandt.nl |url-status=live}}</ref>

In [[American English]], a "t" is usually not aspirated in syllables ending either in a vowel + "t", such as "cat" or "outside"; or in a "t" + unstressed vowel + "n", such as "mountain" or "Manhattan". This is referred to as a "held t" as the airflow is stopped by tongue at the ridge behind the teeth. However, there is a trend of younger speakers in the [[Mid-Atlantic states]] to replace the "held t" with a glottal stop, so that "Manhattan" sounds like "Man-haʔ-in" or "Clinton" like "Cli(n)ʔ-in", where "ʔ" is the glottal stop. This may have crossed over from [[African American Vernacular English]], particularly that of New York City.<ref>{{cite web | url=https://www.chronicle.com/blogs/linguafranca/2012/03/12/that-way-they-talk-ii/ |url-access=registration |first1=Ben |last1=Yagoda |website=The Chronicle of Higher Education | title=((That Way They Talk II)) | date=12 March 2012 |url-status=live |archive-url= https://archive.today/20220121171044/https://www.chronicle.com/blogs/linguafranca/2012/03/12/that-way-they-talk-ii/ |archive-date= 21 Jan 2022 }}</ref><ref>{{Cite journal |last1=Eddington |first1=David |last2=Channer |first2=Caitlin |date=2010-08-01 |title=American English Has Goʔ A Loʔ Of Glottal Stops: Social Diffusion and Linguistic Motivation |url=https://read.dukeupress.edu/american-speech/article/85/3/338/5886/American-English-Has-Go-A-Lo-Of-Glottal-Stops |journal=American Speech |language=en |volume=85 |issue=3 |pages=338–351 |doi=10.1215/00031283-2010-019 |issn=0003-1283}}</ref>
===Before initial vowels===
{{Redirect|hard attack||Hard Attack (disambiguation){{!}}Hard Attack}}
Most English speakers today often use a glottal stop before the initial vowel of words beginning with a vowel, particularly at the beginning of sentences or phrases or when a word is emphasized. This is also known as "hard attack".<ref name="glottal2" /> Traditionally in [[Received Pronunciation]], "hard attack" was seen as a way to emphasize a word. Today, in British, American and other varieties of English, it is increasingly used not only to emphasize but also simply to separate two words, especially when the first word ends in a glottal stop.{{clarify|date=June 2023 |reason= Does this mean the first word already ends in a glottal stop and then a second glottal stop is added to the beginning of the second word?}}<ref name="glottal1">{{cite book |last1=Katz |first1=William F. |title=Phonetics for Dummies |date=5 September 2013 |page=137 |publisher=John Wiley & Sons |isbn=978-1-118-50508-3 |url=https://books.google.com/books?id=5f5dAAAAQBAJ&dq=glottal+stop+initial+vowel+english&pg=PA137 |access-date=26 February 2023}}</ref><ref name="glottal2">{{cite book |last1=Lindsey |first1=Geoff |title=English After RP: Standard British Pronunciation Today |date=2019 |publisher=Springer |isbn=978-3-030-04357-5 |pages=89–92 |url=https://books.google.com/books?id=6nSKDwAAQBAJ&q=glottal |access-date=27 February 2023}}</ref><ref name="glottal3">{{cite journal |last1=Garellek |first1=Marc |title=Glottal stops before word-initial vowels in American English: distribution and acoustic characteristics |journal=UCLA Working Papers in Phonetics |volume=110 |pages=1–23 |url=https://escholarship.org/content/qt7m55b8bb/qt7m55b8bb_noSplash_ad63f821e520155ec5195eaaa435e10f.pdf?t=mezowz |access-date=28 February 2023}}</ref>

==Occurrence in other languages==
In many languages that do not allow a sequence of vowels, such as [[Persian language|Persian]], the glottal stop may be used [[Epenthesis|epenthetically]] to prevent such a [[hiatus (linguistics)|hiatus]]. There are intricate interactions between falling [[tone (linguistics)|tone]] and the glottal stop in the histories of such languages as [[Danish language|Danish]] (see [[stød]]), [[Cantonese]] and [[Thai language|Thai]].{{Citation needed|date=November 2011}}

In many languages, the unstressed intervocalic allophone of the glottal stop is a [[creaky-voiced glottal approximant]]. It is known to be contrastive in only one language, [[Gimi language|Gimi]], in which it is the voiced equivalent of the stop. {{Citation needed|date=September 2017}}
