Subapical retroflex plosive

A retroflex consonant is a coronal consonant where the tongue has a flat, concave, or even curled shape, and is articulated between the alveolar ridge and the hard palate. They are sometimes referred to as cerebral consonants, especially in Indology. Other terms occasionally encountered are apico-domal and cacuminal.

The Latin-derived word retroflex means "bent back"; some retroflex consonants are pronounced with the tongue fully curled back so that articulation involves the underside of the tongue tip (subapical). These sounds are sometimes described as "true" retroflex consonants. However, retroflexes are commonly taken to include other consonants having a similar place of articulation without such extreme curling of the tongue; these may be articulated with the tongue tip (apical) or the tongue blade (laminal).

Types

Retroflex consonants, like other coronal consonants, come in several varieties, depending on the shape of the tongue. The tongue may be either flat or concave, or even with the tip curled back. The point of contact on the tongue may be with the tip (apical), with the blade (laminal), or with the underside of the tongue (subapical). The point of contact on the roof of the mouth may be with the alveolar ridge (alveolar), the area behind the alveolar ridge (postalveolar), or the hard palate (palatal). Finally, both sibilant (fricative or affricate) and nonsibilant (stop, nasal, lateral, rhotic) consonants can have a retroflex articulation.

The greatest variety of combinations occurs with sibilants, because for these, small changes in tongue shape and position cause significant changes in the resulting sound. Retroflex sounds in general have a duller, lower-pitched sound than other alveolar or postalveolar consonants, and especially the grooved alveolar sibilants. The farther back the point of contact with the roof of the mouth, the more concave is the shape of the tongue, and the duller (lower pitched) is the sound, with subapical consonants being the most extreme.

The main combinations normally observed are:

• Laminal post-alveolar, with a flat tongue. These occur, for example, in Polish cz, sz, ż (rz), dż and Mandarin zh, ch, sh, r.


• Apical post-alveolar, with a somewhat concave tongue. These occur, for example, in Hindi and other Indo-Aryan languages. (Hindi has no retroflex sibilants, although some of the other Indo-Aryan languages do.)


• Subapical palatal, with a highly concave tongue. These occur particularly in the Dravidian languages. These are the dullest and lowest-pitched type, and when following a vowel often add strong r-coloring to the vowel, sounding as if an American English r occurs between the vowel and consonant. These are not a place of articulation, as the IPA chart implies, but a shape of the tongue analogous to laminal and apical.^[1]
  

The subapical sounds are sometimes called "true retroflex" because of the curled-back shape of the tongue, while the other sounds sometimes go by other names. For example, Ladefoged and Maddieson^[2] prefer to call the laminal post-alveolar sounds "flat post-alveolar".

Other sounds

Retroflex sounds need to be distinguished from other consonants made in the same parts of the mouth:

• the palato-alveolar consonants (e.g. [ʃ ʒ]), such as the sh, ch and zh occurring in English words like ship, chip and vision
  


• the alveolo-palatal consonants (e.g. [ɕ ʑ]), such as the q, j and x occurring in Mandarin Chinese
  


• the dorsal palatal consonants (e.g. [ç ʝ ɲ]), such as the ch [ç] in German ich or the ñ [ɲ] in Spanish año
  


• the grooved alveolar consonants (e.g. [s z]), such as the s and z occurring in English words like sip and zip
  

The first three types of sounds above have a convex tongue shape, which gives them an additional secondary articulation of palatalization. The last type has a groove running down the center line of the tongue, which gives it a strongly hissing quality. The retroflex sounds, however, have a flat or concave shape, with no associated palatalization, and no groove running down the tongue. The term "retroflex", in fact, literally means "bent back" (concave), although consonants with a flat tongue shape are commonly considered retroflex as well.

Transcription

In the International Phonetic Alphabet, the symbols for retroflex consonants are typically the same as for the alveolar consonants, but with the addition of a right-facing hook to the bottom of the symbol.

Retroflex consonants are transcribed in the International Phonetic Alphabet as follows:

IPA	Description	Example
		Language	Orthography	IPA	Meaning
	retroflex nasal	Swedish	Vänern	[ˈvɛː.neɳ]	Vänern
	voiceless retroflex stop	Hindi	टापू (ṭāpū)	[ʈaːpuˑ]	island
	voiced retroflex stop	Swedish	nord	[nuːɖ]	north
	voiceless retroflex sibilant	Mandarin	上海 (Shànghǎi)	[ʂɑ̂ŋ.xàɪ]	Shanghai
	voiced retroflex sibilant	Russian	жаба	[ˈʐabə]	toad
		Polish	żaba	[ˈʐaba]	frog
	retroflex approximant	Tamil	தமிழ் (Tamil)	[t̪ɐmɨɻ]	Tamil
	retroflex lateral approximant	Swedish	Karlstad	[ˈkʰɑːɭ.sta]	Karlstad
	retroflex flap	Hausa	shaara	[ʃáːɽa]	sweeping
ɭ̆	retroflex lateral flap	Pashto	ړوند	[ɭ̆und]	blind
ꞎ	voiceless retroflex lateral fricative	Toda		[pʏːꞎ]	summer
ǃ˞ (‼)	retroflex click release (many distinct consonants)	Ekoka !Kung	—	[ɡǃ˞ú]	water

Some linguists restrict these symbols for consonants with subapical palatal articulation, in which the tongue is curled back and contacts the hard palate, and use the alveolar symbols with the obsolete IPA underdot symbol for an apical post-alveolar articulation: ⟨ṭ, ḍ, ṇ, ṣ, ẓ, ḷ, ɾ̣, ɹ̣⟩.

Laminal retroflexes, as in Polish and Russian, are often transcribed with a retraction diacritic, as ⟨s̠⟩. Otherwise they are typically but inaccurately transcribed as if they were palato-alveolar, as ⟨*ʃ⟩.

Consonants with more forward articulation, in which the tongue touches the Alveolar or postalveolar region rather than the hard palate, can be indicated with the retracted diacritic (minus sign below). This occurs especially for [s̱ ẕ]; other sounds indicated this way, such as ⟨ṉ ḻ ḏ⟩, tend to refer to alveolo-palatal rather than retroflex consonants.

Occurrence

Although data is not precise, about 20 percent of the world's languages contain retroflex consonants of one sort or another.^[3] About half of these possess only retroflex continuants, with most of the rest having both stops and continuants.

Retroflex consonants are concentrated in the Indian subcontinent, particularly in the Indo-Aryan and Dravidian languages, but are found in other languages of the region as well, such as the Munda languages and Burushaski. The Nuristani languages of eastern Afghanistan also have retroflex consonants. Among Eastern Iranian languages, they are common in Pashto, Wakhi, Sanglechi-Ishkashimi, and Munji-Yidgha. They also occur in some other Asian languages such as Mandarin Chinese, Javanese and Vietnamese.

The other major concentration is in the indigenous languages of Australia and the Western Pacific (notably New Caledonia). Here, most languages have retroflex plosives, nasal and approximants.

Retroflex consonants are relatively rare among European languages but are used in such languages as Swedish and Norwegian in Northern Europe, some Romance languages of Southern Europe (Sardinian, Sicilian, including Calabrian and Salentino, some Italian dialects such as Lunigianese in Italy, and some Asturian dialects in Spain), and (sibilants only) Faroese and several Slavic languages (Polish, Russian, Serbo-Croatian, Slovak and Sorbian). In Swedish and Norwegian, a sequence of r plus a coronal consonant may be replaced by the coronal's retroflex equivalent, e.g. the name Martin is pronounced [ˈmaʈːɪn] (Swedish) or [ˈmɑʈːɪn] (Norwegian), and nord ("north") is pronounced [ˈnuːɖ]. This is sometimes done for several consonants in a row after an r — Hornstull is pronounced [huːɳʂˈʈɵlː]).

The retroflex approximant /ɻ/ is an allophone of the alveolar approximant /ɹ/ in many dialects of American English, particularly in the Midwestern United States. Polish and Russian possess retroflex sibilants, but no stops or liquids at this place of articulation.

Retroflex consonants are largely absent from indigenous languages of the Americas with the exception of the extreme south of South America, an area in Southwestern US as in Hopi and O'odham, and in Alaska and the Yukon Territory as in the Athabaskan languages Gwich’in and Hän. In African languages retroflex consonants are also rare, reportedly occurring in a few Nilo-Saharan languages, as well as in the Bantu language Makhuwa and some other varieties. In southwest Ethiopia, phonemically distinctive retroflex consonants are found in Bench and Sheko, two contiguous, but not closely related, Omotic languages.^[4]

There are several retroflex consonants not yet recognized by the IPA. For example, the Iwaidja language of northern Australia has a retroflex lateral flap [ɺ̢] as well as a retroflex tap [ɽ] and retroflex lateral approximant [ɭ]; and the Dravidian language Toda has a subapical retroflex lateral fricative [ɬ̢] and a retroflexed trill [ɽ͡r]. Because of the regularity of deriving retroflex symbols from their alveolar counterparts, people will occasionally use a font editor to create the appropriate symbols for such sounds. (Here they were written with diacritics.) The Ngad'a language of Flores has been reported to have a retroflex implosive [ᶑ], but in this case the expected symbol is coincidentally supported by Unicode. Subapical retroflex clicks occur in Central Juu and in Damin.^{[citation needed]}

Most languages with retroflex sounds typically have only one retroflex sound with a given manner of articulation. An exception, however, is the Toda language, with a two-way distinction among retroflex sibilants between apical (post)alveolar and subapical palatal.
