A retroflex () or cacuminal () 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.

-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
In articulatory phonetics, the place of articulation (also point of articulation) of a consonant is an approximate location along the vocal tract where its production occurs. It is a point where a constriction is made between an active and a pa ...
without such extreme curling of the tongue; these may be articulated with the tongue tip (
apical) or the tongue blade (
laminal). When apical, they have been called apico-domal consonants.
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

( or ) and nonsibilant (, , , ) consonants can have a retroflex articulation.
The greatest variety of combinations occurs with sibilants, because for them, small changes in tongue shape and position cause significant changes in the resulting sound. Retroflex sounds generally have a duller, lower-pitched sound than other alveolar or postalveolar consonants, 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''.
*Apical post-alveolar, with a somewhat concave tongue. These occur, for example, in

''r'' occurred between the vowel and consonant. They are not a place of articulation, as the IPA chart implies, but a shape of the tongue analogous to laminal and apical.
Subapical sounds are sometimes called "true retroflex" because of the curled-back shape of the tongue, and the other sounds sometimes go by other names. For example,
Ladefoged and
Maddieson prefer to call the laminal post-alveolar sounds "flat post-alveolar".
Other sounds
Retroflex sounds must be distinguished from other consonants made in the same parts of the mouth:

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 strong 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.

Other conventions
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: , and use for laminal retroflex, as in Polish and Russian.
The latter are also often transcribed with a retraction diacritic, as . Otherwise they are typically but inaccurately transcribed as if they were palato-alveolar, as .
