Geminate consonant

In phonetics and phonology, gemination (), or consonant lengthening (from Latin 'doubling', itself from ''gemini'' 'twins'), is an articulation of a consonant for a longer period of time than that of a singleton consonant. It is distinct from stress. Gemination is represented in many writing systems by a doubled letter and is often perceived as a doubling of the consonant.William Ham, ''Phonetic and Phonological Aspects of Geminate Timing'', p. 1-18 Some phonological theories use "doubling" as a synonym for gemination, others describe two distinct phenomena.

Consonant length is a distinctive feature in certain languages, such as Arabic, Berber, Danish, Estonian, Hindi, Hungarian, Italian, Japanese, Kannada, Punjabi, Polish and Turkish. Other languages, such as English, do not have word-internal phonemic consonant geminates.

Consonant gemination and vowel length are independent in languages like Arabic, Japanese, Finnish and Estonian; however, in languages like Italian, Norwegian and Swedish, vowel length and consonant length are interdependent. For example, in Norwegian and Swedish, a geminated consonant is always preceded by a short vowel, while an ungeminated consonant is preceded by a long vowel. A clear example are the Norwegian words ('ceiling or roof' of a building), and ('thanks').

Phonetics

Lengthened fricatives, nasals, laterals, approximants and trills are simply prolonged. In lengthened stops, the obstruction of the airway is prolonged, which delays release, and the "hold" is lengthened.

In terms of consonant duration, Berber and Finnish are reported to have a 3-to-1 ratio, compared with around 2-to-1 (or lower) in Japanese, (URL is author's "near final version" draft) Italian, and Turkish.

Phonology

Gemination of consonants is distinctive in some languages and then is subject to various phonological constraints that depend on the language.

In some languages, like Italian, Swedish, Faroese, Icelandic, and Luganda, consonant length and vowel length depend on each other. A short vowel within a stressed syllable almost always precedes a long consonant or a consonant cluster, and a long vowel must be followed by a short consonant. In Classical Arabic, a long vowel was lengthened even more before permanently-geminate consonants.

In other languages, such as Finnish, consonant length and vowel length are independent of each other. In Finnish, both are phonemic; 'back', 'fireplace' and 'burden' are different, unrelated words. Finnish consonant length is also affected by consonant gradation. Another important phenomenon is sandhi, which produces long consonants at word boundaries when there is an archiphonemic glottal stop > 'take it!'

In addition, in some Finnish compound words, if the initial word ends in an , the initial consonant of the following word is geminated: 'trash bag' , 'welcome' . In certain cases, a after a is geminated by most people: 'screw' , 'baby' . In the Tampere dialect, if a word receives gemination of after , the is often deleted ( , ), and 'Saturday', for example, receives a medial , which can in turn lead to deletion of ( ).

Distinctive consonant length is usually restricted to certain consonants. There are very few languages that have initial consonant length; among them are Pattani Malay, Chuukese, Moroccan Arabic, a few Romance languages such as Sicilian and Neapolitan as well as many High Alemannic German dialects, such as that of Thurgovia. Some African languages, such as Setswana and Luganda, also have initial consonant length: it is very common in Luganda and indicates certain grammatical features. In colloquial Finnish and in Italian, long consonants occur in specific instances as sandhi phenomena.

The difference between singleton and geminate consonants varies within and across languages. Sonorants show more distinct geminate-to-singleton ratios while sibilants have less distinct ratios. The bilabial and alveolar geminates are generally longer than velar ones.

The reverse of gemination reduces a long consonant to a short one, which is called ''degemination''. It is a pattern in Baltic-Finnic consonant gradation that the strong grade (often the nominative) form of the word is degeminated into a weak grade (often all the other cases) form of the word: > (burden, of the burden). As a historical restructuring at the phonemic level, word-internal long consonants degeminated in Western Romance languages: e.g. Spanish /ˈboka/ 'mouth' vs. Italian /ˈbokka/, both of which evolved from Latin /ˈbukka/.

Examples

Afroasiatic languages

Arabic

Written Arabic indicates gemination with a diacritic ( ) shaped like a lowercase Greek omega or a rounded Latin ''w'', called the : . Written above the consonant that is to be doubled, the is often used to disambiguate words that differ only in the doubling of a consonant where the word intended is not clear from the context. For example, in Arabic, Form I verbs and Form II verbs differ only in the doubling of the middle consonant of the triliteral root in the latter form, ''e. g.'', (with full diacritics: ) is a Form I verb meaning ''to study'', whereas (with full diacritics: ) is the corresponding Form II verb, with the middle consonant doubled, meaning ''to teach''.

Berber

In Berber, each consonant has a geminate counterpart, and gemination is lexically contrastive. The distinction between single and geminate consonants is attested in medial position as well as in absolute initial and final positions.

* 'say'
* 'those in question'
* 'earth, soil'
* 'loss'
* 'mouth'
* 'mother'
* 'hyena'
* 'he was quiet'
* 'pond, lake, oasis'
* 'brown buzzard, hawk'

In addition to lexical geminates, Berber also has phonologically-derived and morphologically-derived geminates . Phonologically-derived geminates can surface by concatenation (e.g. 'give him two!') or by complete assimilation (e.g. 'he will touch you'). The morphological alternations include imperfective gemination, with some Berber verbs forming their
imperfective stem by geminating one consonant in their perfective stem (e.g. 'go! PF', 'go! IMPF'), as well as quantity alternations between singular and plural forms (e.g. 'hand', 'hands').

Austronesian languages

Austronesian languages in the Philippines, Micronesia, and Sulawesi are known to have geminate consonants.Blust, Robert. (2013). ''The Austronesian Languages (Rev. ed.)''. Australian National University.

Kavalan

The Formosan language Kavalan makes use of gemination to mark intensity, as in 'bad' vs. 'very bad'.

Malay dialects

Word-initial gemination occurs in various Malay dialects, particularly those found on the east coast of the Malay Peninsula such as Kelantan-Pattani Malay and Terengganu Malay. Gemination in these dialects of Malay occurs for various purposes such as:

* To form a shortened free variant of a word or phrase so that:
** > 'give'
** > 'to/at/from the shore'
* A replacement of reduplication for its various uses (e.g. to denote plural, to form a different word, etc.) in Standard Malay so that:
** > 'children'
** > 'kite'

Tuvaluan

The Polynesian language Tuvaluan allows for word-initial geminates, such as 'overcooked'.

Indo-European languages

English

In English phonology, consonant length is not distinctive within root words. For instance, ''baggage'' is pronounced , not . However, phonetic gemination does occur marginally.

Gemination is found across words and across morphemes when the last consonant in a given word and the first consonant in the following word are the same fricative, nasal, or stop.

For instance:
* b: ''subbasement''
* d: ''midday''
* f: ''life force''
* g: ''egg girl''
* k: ''bookkeeper''
* l: ''guileless''
* m: ''calm man'' or ''roommate'' (in some dialects) or ''prime minister''
* n: ''evenness''
* p: ''lamppost'' (cf. lamb post, compost)
* r: ''fire road''
* s: ''misspell'' or ''this saddle''
* sh: ''fish shop''
* t: ''cattail''
* th: ''both thighs''
* v: ''live voter''
* z: ''pays zero''

With affricates, however, this does not occur. For instance:
* ''orange juice''

In most instances, the absence of this doubling does not affect the meaning, though it may confuse the listener momentarily. The following minimal pairs represent examples where the doubling ''does'' affect the meaning in most accents:

* ''ten nails'' versus ''ten ales''
* ''this sin'' versus ''this inn''
* ''five valleys'' versus ''five alleys''
* ''his zone'' versus ''his own''
* ''mead day'' versus ''me-day''
* ''unnamed'' versus ''unaimed''
* ''forerunner'' versus ''foreigner'' (only in some varieties of General American)

In some dialects gemination is also found for some words when the suffix ''-ly'' follows a root ending in -l or -ll, as in:
* ''solely''
but not
* ''usually''

In some varieties of Welsh English, the process takes place indiscriminately between vowels, e.g. in ''money'' but it also applies with graphemic duplication (thus, orthographically dictated), e.g. ''butter''

French

In French, gemination is usually not phonologically relevant and therefore does not allow words to be distinguished: it mostly corresponds to an accent of insistence ("c'est terrifiant" realised �tɛʁ.ʁi.fjɑ̃, or meets hyper-correction criteria: one "corrects" one's pronunciation, despite the usual phonology, to be closer to a realization that one imagines to be more correct: thus, the word illusion is sometimes pronounced l.lyˈzjɔ̃by influence of the spelling.

However, gemination is distinctive in a few cases. Statements such as She said ~ She said it /ɛl a di/ ~ /ɛl l‿a di/ can commonly be distinguished by gemination. In a more sustained pronunciation, gemination distinguishes the conditional (and possibly the future tense) from the imperfect: ''courrai'' (will run) /kuʁ.ʁɛ/ vs. ''courais'' (ran) /ku.ʁɛ/, or the indicative from the subjunctive, as in ''croyons'' (we believe) /kʁwa.jɔ̃ / vs. ''croyions'' (we believed) /kʁwaj.jɔ̃ /.

Greek

In Ancient Greek, consonant length was distinctive, e.g., 'I am of interest' vs. 'I am going to'. The distinction has been lost in the standard and most other varieties, with the exception of Cypriot (where it might carry over from Ancient Greek or arise from a number of synchronic and diachronic assimilatory processes, or even spontaneously), some varieties of the southeastern Aegean, and Greek-Bovesian, Italy.

Hindustani

Gemination is common in both Hindi and Urdu. It does not occur after long vowels and is found in words of both Indic and Arabic origin, but not in those of Persian origin. In Urdu, gemination is represented by the Shadda diacritic, which is usually omitted from writings, and mainly written to clear ambiguity. In Hindi, gemination is represented by doubling the geminated consonant, enjoined with the Virama diacritic.

=Aspirated consonants

=
Gemination of aspirated consonants in Hindi are formed by combining the corresponding non-aspirated consonant followed by its aspirated counterpart. In vocalised Urdu, the shadda is placed on the unaspirated consonant followed by the Arabic diacritics, short vowel diacritic, followed by the ''Urdu alphabet#Alphabet, do-cashmī hē'', which aspirates the preceding consonant. There are few examples where an aspirated consonant is truly doubled.

Italian

Italian is notable among the Romance languages for its extensive geminated consonants. In Italian language, Standard Italian, word-internal geminates are usually written with two consonants, and geminates are distinctive. For example, , meaning 'he/she drank', is phonemically and pronounced , while ('he/she drinks/is drinking') is , pronounced . Tonic syllables are mora (linguistics), bimoraic and are therefore composed of either a long vowel in an open syllable (as in ) or a short vowel in a closed syllable (as in ). In varieties with post-vocalic lenition, weakening of some consonants (e.g. → 'reason'), geminates are not affected ( → 'May').

Double or long consonants occur not only within words but also at word boundaries, and they are then pronounced but not necessarily written: + = ('who knows') and ('I am going home') . All consonants except can be geminated. This word-initial gemination is triggered either lexically by the item preceding the lengthening consonant (e.g. by preposition 'to, at' in [a kˈkaːsa] 'homeward' but not by definite article in [la ˈkaːsa] 'the house'), or by any word-final stressed vowel ([] 's/he spoke French' but [] 'I speak French').

Latin

In Latin, consonant length was distinctive, as in 'old woman' vs. 'year'. Vowel length was also distinctive in Latin, but was not reflected in the orthography. Geminates inherited from Latin still exist in Italian, in which and contrast with regard to and as in Latin. It has been almost completely lost in French language, French and completely in Romanian language, Romanian. In West Iberian languages, former Latin geminate consonants often evolved to new phonemes, including some instances of nasal vowels in Portuguese language, Portuguese and Old Galician language, Galician as well as most cases of and in Spanish, but phonetic length of both consonants and vowels is no longer distinctive.

Nepali

In Nepali language, Nepali, all consonants have geminate counterparts except for . Geminates occur only medially. Examples:

* – 'equal' ; – 'honour'
* – 'disturb!' ; – 'authority'
* – 'cook!' ; – 'certain'

Norwegian

In Norwegian, gemination is indicated in writing by double consonants. Gemination often differentiates between unrelated words. As in Italian, Norwegian uses short vowels before doubled consonants and long vowels before single consonants. There are qualitative differences between short and long vowels:

* / – 'method' / 'must'
* / – 'to search' / 'to take off'
* / – 'theirs' / 'anger'

Polish

In Polish, consonant length is indicated with two identical letters. Examples:

* – 'bathtub'
*
* – 'horror'
* or – 'hobby'

Consonant length is distinctive and sometimes is necessary to distinguish words:

* – 'families'; – 'familial'
* – 'sacks, bags'; – 'mammals',
* – 'medicines'; – 'light, lightweight'

Double consonants are common on morpheme borders where the initial or final sound of the suffix is the same as the final or initial sound of the stem (depending on the position of the suffix). Examples:

* – 'before, previously'; from (suffix 'before') + (archaic 'that')
* – 'give back'; from (suffix 'from') + ('give')
* – 'swampy'; from ('swamp') + (suffix forming adjectives)
* – 'brightest'; from (suffix forming superlative) + ('brighter')

Punjabi

Punjabi is written in two scripts, namely, Gurmukhi script, Gurmukhi and Shahmukhi alphabet, Shahmukhi. Both scripts indicate gemination through the uses of diacritics. In Gurmukhi the diacritic is called the which is written ''before'' the geminated consonant and is mandatory. In contrast, the ''shadda'', which is used to represent gemination in the Shahmukhi alphabet, Shahmukhi script, is not necessarily written, retaining the tradition of the original Arabic script and Persian language, where diacritics are usually omitted from writing, except to clear ambiguity, and is written ''above'' the geminated consonant. In the cases of aspirated consonants in the Shahmukhi script, the ''shadda'' remains on the consonant, not on the Shahmukhi alphabet#Consonants, ''do-cashmī he''.

Gemination is specially characteristic of Punjabi compared to other Indo-Aryan languages like Hindi-Urdu, where instead of the presence of consonant lengthening, the preceding vowel tends to be lengthened. Consonant length is distinctive in Punjabi, for example:

Russian

In Russian language, Russian, consonant length (indicated with two letters, as in 'bathtub') may occur in several situations.

Minimal pairs (or chronemes) exist, such as 'to hold' vs 'to support', and their conjugations, or 'length' vs 'long' adj. f.

*Word formation or Grammatical conjugation, conjugation: ( 'length') > ( 'long') This occurs when two adjacent morphemes have the same consonant and is comparable to the situation of Polish described above.
*Assimilation (linguistics), Assimilation. The spelling usually reflects the unassimilated consonants, but they are pronounced as a single long consonant.
** ( 'highest').

Spanish

There are phonetic geminate consonants in Caribbean Spanish due to the assimilation of /l/ and /ɾ/ in syllabic coda to the following consonant. Examples of Cuban Spanish:

Luganda

Luganda is unusual in that gemination can occur word-initially, as well as word-medially. For example, 'cat', 'grandfather' and 'madam' all begin with geminate consonants.

There are three consonants that cannot be geminated: , and . Whenever morphology (linguistics), morphological rules would geminate these consonants, and are prefixed with , and changes to . For example:
* 'army' (root) > 'an army' (noun)
* 'stone' (root) > 'a stone' (noun); is usually spelt
* 'nation' (root) > 'a nation' (noun)
* 'medicine' (root) > 'medicine' (noun)

Japanese

In Japanese, consonant length is distinctive (as is vowel length). Gemination in the syllabary is represented with the sokuon, a small : for hiragana in native words and for katakana in foreign words. For example, (, ) means 'came; arrived', while (, ) means 'cut; sliced'. With the influx of ''gairaigo'' ('foreign words') into Modern Japanese, voiced consonants have become able to geminate as well: () means '(computer) bug', and () means 'bag'. Distinction between voiceless gemination and voiced gemination is visible in pairs of words such as (, meaning 'kit') and (, meaning 'kid'). In addition, in some variants of colloquial Modern Japanese, gemination may be applied to some adjectives and adverbs (regardless of voicing) in order to add emphasis: (, 'amazing') contrasts with (, '''really'' amazing'); (, , 'with all one's strength') contrasts with (, , really'' with all one's strength').

Turkish

In Turkish gemination is indicated by two identical letters as in most languages that have phonemic gemination.

*
*

Loanwords originally ending with a phonemic geminated consonant are always written and pronounced without the ending gemination as in Arabic.

* (hajj) (from Arabic pronounced )
* (Islamic calligraphy) (from Arabic pronounced )

Although gemination is resurrected when the word takes a suffix.

* becomes ('to hajj') when it takes the suffix "-a" ('to', indicating destination)
* becomes ('of calligraphy') when it takes the suffix "-ın" ('of', expressing possession)

Gemination also occurs when a suffix starting with a consonant comes after a word that ends with the same consonant.

* ('hand') + ("-s", marks plural) = ('hands'). (contrasts with , 's/he eliminates')
* ('to throw') + ("-ed", marks past tense, Grammatical person, first person plural) = ('we threw [smth.]'). (contrasts with , 'waste')

Malayalam

In Malayalam, compounding is phonologically conditioned so gemination occurs at words' internal boundaries.

Consider following example:

* + ( + ) – ()

Gemination also occurs in a single morpheme like () which has a different meaning from ().

Uralic languages

Estonian

Estonian has three phonemic lengths; however, the third length is a suprasegmental feature, which is as much tonal patterning as a length distinction. It is traceable to allophony caused by now-deleted suffixes, for example half-long < * 'of the city' vs. overlong < * < * 'to the city'.

Finnish

Consonant length is phonemic in Finnish, for example ('fireplace', transcribed with the length sign or with a doubled letter ) and ('back'). Consonant gemination occurs with simple consonants ( : ) and between syllables in the pattern (consonant)-vowel-sonorant-stop-stop-vowel () but not generally in codas or with longer syllables. (This occurs in Sami languages and in the Finnish name , which is of Sami origin.) Sandhi often produces geminates.

Both consonant and vowel gemination are phonemic, and both occur independently, e.g. , , , (Karelian surname, 'paint', 'model', and 'secular').

In Standard Finnish, consonant gemination of exists only in interjections, new loan words and in the playful word wikt:hihhuli, ''hihhuli'', with its origins in the 19th century, and derivatives of that word.

In many Finnish dialects there are also the following types of special gemination in connection with long vowels: the southwestern special gemination (), with lengthening of stops + shortening of long vowel, of the type < ; the common gemination (), with lengthening of all consonants in short, stressed syllables, of the type > and its extension (which is strongest in the northwestern Savonian dialects); the eastern dialectal special gemination (), which is the same as the common gemination but also applies to unstressed syllables and certain clusters, of the types > and > .

Wagiman

In Wagiman language, Wagiman, an Indigenous Australian languages, indigenous Australian language, consonant length in stops is the primary phonetic feature that differentiates fortis and lenis stops. Wagiman does not have phonetic voice. Word-initial and word-final stops never contrast for length.

Writing

In writing, written language, consonant length is often indicated by writing a consonant twice (''ss'', ''kk'', ''pp'', and so forth), but can also be indicated with a special symbol, such as the shadda in Arabic, the dagesh in Classical Hebrew, or the sokuon in Japanese.

In the International Phonetic Alphabet, long consonants are normally written using the triangular colon , e.g. ''penne'' ('feathers', 'pens', also a kind of pasta), though doubled letters are also used (especially for underlying phonemic forms, or in tone languages to facilitate diacritic marking).

* Catalan orthography, Catalan uses the raised dot (called an interpunct) to distinguish a geminated from a palatal . Thus, ('parallel') and (Standard Catalan: , ).
* Estonian uses ''b'', ''d'', ''g'' for short consonants, and ''p'', ''t'', ''k'' and ''pp'', ''tt'', ''kk'' are used for long consonants.
* Hungarian alphabet, Hungarian digraphs and trigraphs are geminated by doubling the first letter only, thus the geminate form of is (rather than *''szsz''), and that of is .
* The only digraph in Luganda, Ganda, is doubled in the same way: .
* In Italian, geminated instances of the sound cluster (represented by the digraph ) are always indicated by writing , except in the words and , where the letter is doubled. The gemination of sounds , and , (spelled , , and , respectively) is not indicated because these consonants are always geminated when occurring between vowels. Also the sounds , (both spelled ) are always geminated when occurring between vowels, yet their gemination is sometimes shown, redundantly, by doubling the as, e.g., in .
*In Japanese, non-nasal gemination () is denoted by placing the "small" variant of the syllable ( or ) between two syllables, where the end syllable must begin with a consonant. For nasal gemination, precede the syllable with the letter for mora N ( or ). The script of these symbols must match with the surrounding syllables.
* In Swedish and Norwegian, the general rule is that a geminated consonant is written double, unless succeeded by another consonant. Hence ('hall'), but ('Halt!'). In Swedish, this does not apply to morphological changes (so , 'cold' and , 'coldly' or compounds [so ('flatbread')]. The exception are some words ending in ''-m'', thus ['home'] [but ('at home')] and ['stem'], but ['lamb', to distinguish the word from ('lame')], with a long /), as well as adjectives in ''-nn'', so , 'thin' but , 'thinly' (while Norwegian has a rule always prohibiting two "m"s at the end of a word (with the exception being only a handful of proper names, and as a rule forms with suffixes reinsert the second "m", and the rule is that these word-final "m"s always cause the preceding vowel sound to be short (despite the spelling)).

Double letters that are not long consonants

Doubled orthographic consonants do not always indicate a long phonetic consonant.

* In English, for example, the sound of ''running'' is not lengthened. Consonant digraphs are used in English to indicate the preceding vowel is a short (lax) vowel, while a single letter often allows a long (tense) vowel to occur. For example, ''tapping'' (from ''tap'') has a short ''a'' , which is distinct from the diphthongal long ''a'' in ''taping'' (from ''tape'').
* In Standard Modern Greek, doubled orthographic consonants have no phonetic significance at all.
* Hangul (the Korean alphabet) and Korean romanization, its romanizations also use double consonants, but to indicate Fortis and lenis, fortis articulation, not gemination.
* In Klallam language, Klallam, a sequence of two sounds such as in a word like 'sleep' is not pronounced like a geminated stop with a long closure duration – rather the sequence is pronounced as a sequence of two individual sounds such that the first is released before the articulation of the second .
