Glottal stop

A glottal stop or glottal plosive is a type of consonantal sound used in many spoken languages, 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 Template:Angbr IPA.

As a result of the airflow in the glottis, the glottal vibration either stops or becomes irregular with a low rate and sudden drop in intensity.

Features

Features of a glottal stop:

• It has no phonation at all, as there is no airflow through the glottis. It is voiceless, however, in the sense that it is produced without vibrations of the vocal cords.

In the traditional romanization of many languages, such as Arabic, a glottal stop is transcribed with the apostrophe [[ʼ|Template:Angle bracket]] or the symbol [[ʾ|Template:Angbr]], which is the source of the IPA character Template:Angbr IPA. In many Polynesian languages that use the Latin alphabet, however, the glottal stop is written with a rotated apostrophe, Template:Angbr (called ʻokina in Hawaiian and Samoan), which is commonly used to transcribe the Arabic ayin as well (also Template:Angbr) and is the source of the IPA character for the voiced pharyngeal fricative Template:Angbr IPA. In Malay the glottal stop is represented by the letter Template:Angbr (at the end of words), in Võro and Maltese by Template:Angbr. Another way of writing the glottal stop is the saltillo Template:Angbr, used in languages such as Tlapanec and Rapa Nui.

Other scripts also have letters used for representing glottal stops, such as the Hebrew letter aleph Template:Angbr and the Cyrillic letter palochka Template:Angbr, used in several Caucasian languages. The Arabic script uses hamza Template:Angbr, which can appear both as a diacritic and as an independent letter (though not part of the alphabet). In Tundra Nenets, it is represented by the letters apostrophe Template:Angbr and double apostrophe Template:Angbr. In Japanese, glottal stops occur at the end of interjections of surprise or anger and are represented by the character Template:Angbr.

In the graphic representation of most Philippine languages, glottal stops have no consistent symbolization. In most cases, however, a word that begins with a vowel-letter (e.g. Tagalog , "dog") is always pronounced with an unrepresented glottal stop before that vowel (as in Modern German and 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 , "love"; or Visayan , "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").

Some Canadian indigenous languages, especially some of the Salishan languages, have adopted the IPA letter Template:Angbr into their orthographies. In some of them, it occurs as a casing pair, [[glottal stop (letter)|Template:Angbr and Template:Angbr]]. The digit Template:Angbr or a question mark is sometimes substituted for Template:Angbr, and is preferred in languages such as Squamish.

In 2015, two women in the Northwest Territories challenged the territorial government over its refusal to permit them to use the letter Template:Angbr in their daughters' names: Sahaiʔa, a Chipewyan name, and Sakaeʔah, a Slavey name (the two names are actually cognates). 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 Template:Angbr, while continuing to challenge the policy.

In the Crow language, the glottal stop is written as a question mark Template:Angbr. The only instance of the glottal stop in Crow is as a question marker morpheme at the end of a sentence.

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 ("I speak Gaelic"), would be rendered .

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!,) 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 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.

Although this segment is not a phoneme in English, it occurs phonetically in nearly all dialects of English, as an allophone of in the syllable coda. Speakers of Cockney, Scottish English and several other British dialects also pronounce an intervocalic between vowels as in city. In Received Pronunciation, a glottal stop is inserted before a tautosyllabic voiceless stop: stoTemplate:Hamzap, thaTemplate:Hamzat, knoTemplate:Hamzack, waTemplate:Hamzatch, also leaTemplate:Hamzap, soaTemplate:Hamzak, helTemplate:Hamzap, pinTemplate:Hamzach.

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.

Before initial vowels

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". 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.Template:Clarify

Occurrence in other languages

In many languages that do not allow a sequence of vowels, such as Persian, the glottal stop may be used epenthetically to prevent such a hiatus. There are intricate interactions between falling tone and the glottal stop in the histories of such languages as Danish (see stød), Cantonese and Thai.

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, in which it is the voiced equivalent of the stop.
