Coronal consonant in the context of "Alveolar consonant"

An affricate is a consonant that begins as a stop and releases as a fricative, generally with the same place of articulation (most often coronal). It is often difficult to decide if a stop and fricative form a single phoneme or a consonant pair. English has two affricate phonemes, /t͡ʃ/ and /d͡ʒ/, generally spelled ch and j, respectively.

Labial consonants are consonants in which one or both lips are the active articulator. The two common labial articulations are bilabials, articulated using both lips, and labiodentals, articulated with the lower lip against the upper teeth, both of which are present in English. A third labial articulation is dentolabials, articulated with the upper lip against the lower teeth (the reverse of labiodental), normally only found in pathological speech. Generally precluded are linguolabials, in which the tip of the tongue contacts the posterior side of the upper lip, making them coronals, though sometimes, they behave as labial consonants.

The most common distribution between bilabials and labiodentals is the English one, in which the nasal and the stops, [m], [p], and [b], are bilabial and the fricatives, [f], and [v], are labiodental. The voiceless bilabial fricative, voiced bilabial fricative, and the bilabial approximant do not exist as the primary realizations of any sounds in English, but they occur in many languages. For example, the Spanish consonant written b or v is pronounced, between vowels, as a voiced bilabial approximant.

A retroflex (/ˈrɛtrəflɛks, -roʊ-/ ) or cacuminal (/kəˈkjuːmɪnəl/ ) 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.

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). When apical, they have been called apico-domal consonants.

A laminal consonant is a phone (speech sound) produced by obstructing the air passage with the blade of the tongue, the flat top front surface just behind the tip of the tongue, in contact with upper lip, teeth, alveolar ridge, to possibly, as far back as the hard palate, although in the last contact may involve parts behind the blade as well. It is distinct from an apical consonant, produced by creating an obstruction with the tongue apex (tongue tip) only. Laminal is sometimes used exclusively for an articulation that involves only the blade of the tongue with the tip being lowered and apicolaminal for an articulation that involves both the blade of the tongue and the raised tongue tip. The distinction applies only to coronal consonants, which use the front of the tongue.

Dorsal consonants are consonants articulated with the back of the tongue (the dorsum). They include the uvular, velar and, in some cases, alveolo-palatal and palatal consonants. They contrast with coronal consonants, articulated with the flexible front of the tongue, and laryngeal consonants, articulated in the pharyngeal cavity.
