Retroflex Consonant

High Quality Content by WIKIPEDIA articles! In phonetics, retroflex consonants are consonant sounds used in some languages. (They are sometimes referred to as cerebral consonants, especially in Indology.) The tongue articulates with the roof of the oral cavity behind the alveolar ridge, and may even be curled back to touch the palate: that is, they are articulated in the postalveolar to palatal region of the mouth. Retroflex consonants, like other coronals, come in several varieties, depending on the shape of the tongue. The tongue may be flat, with the blade of the tongue (the top surface of the tongue near the tip) approaching or touching the roof of the mouth, as in Polish cz, sz, ? (rz), d? and Mandarin zh, ch, sh, r. This is termed laminal (laminal retroflex). Or they may be pronounced with the tip of the tongue, as in Hindi. This is termed apical (apical retroflex). Finally, the tongue may be curled back so that the underside touches the alveolar or pre-palatal region, as in many of the Dravidian languages. This is termed sub-apical (sub-apical retroflex).
