Retroflex consonant

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 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 (), with the blade (), or with the underside of the tongue (). The point of contact on the roof of the mouth may be with the alveolar ridge (), the area behind the alveolar ridge (), or the hard palate (). Finally, both sibilant ( or ) and nonsibilant (, , , ) 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 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.〔John Esling, 2010, "Phonetic Notation". In Hardcastle, Laver, & Gibbon, eds, ''The Handbook of Phonetic Sciences'', p 693〕
*Apical alveolar, with a somewhat concave tongue. These occur, for example, in peninsular Spanish and Basque. These sounds don't quite fit on the front-to-back, laminal-to-subapical continuum, with a relatively dull but higher pitched sound.
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 prefer to call the laminal post-alveolar sounds "flat post-alveolar", and the apical alveolar sounds are often referred to simply as "apico-alveolar" (which is ambiguous with, and often confused with, other apical alveolar sounds such as the apical variety of the voiceless alveolar sibilant (English ).
