Place of articulation

In speech, consonants may have different places of articulation, generally with full or partial stoppage of the airstream. The descriptions below list positions where the obstruction may occur:

Bilabial, between the lips
Labiodental, between the lip and teeth
Linguolabial, between the lip and the tongue tip
Dental, between the top teeth and tongue tip
Alveolar, between the gum ridge and tongue, above dental
Postalveolar, between the palatal ridge and tongue, behind alveolar position
Palatal, between the tongue and the palate ("hard palate")
Retroflex, tongue curled back to face the palate (tongue curled so tip of underside touches the roof of the mouth)
Velar, between the tongue and back palate (velum, "soft palate")
Uvular, between the tongue and uvula (back of throat)
Nasal, any of the above-listed positions pronounced with the velum lowered to allow air to pass through the nose (technically a place, but generally considered as a manner of articulation)

In addition, the following positions may occur (but these cannot be nasalised due to their articulatory position):

Pharyngeal, behind the velum (the muscles used to suppress a belch and/or other less pleasant phenomena)
Epiglottal, at the epiglottis; only a few languages contrast such sounds with pharyngeals
Glottal or laryngeal, at the glottis (in the throat, where the larynx prevents food from entering the lungs)

Also:

In laterals, the air is released past the tongue sides and teeth rather than over the tip of the tongue, and is technically a manner of articulation, not a place of articulation. English speakers often treat this as a separate position because English only has one lateral, /l/. Many languages have more than one, e.g. Spanish written "l" vs. "ll"; Hindi with dental, palatal, and retroflex laterals; and numerous Native American languages with not only lateral approximants, but also lateral fricatives and affricates. Some Northeast Caucasian languages have five, six, or even seven lateral consonants.

Some languages have sounds with two places of articulation. Some common coarticulations include:

Labialization, rounding or closing the lips while producing the obstruction (often written ^w)
Palatalization, raising the tongue body to palatal position while producing the obstruction (often written ^y or ^j)
Velarization, raising the back of the tongue to velar position (no standard method of representation)
Fricative coarticulation: usually a velar fricative (often written ^x) or pharyngeal fricative (often written with a superscript mirror-imaged question mark symbol)
- Fricative release is a term that can be used in describing affricates, which are stops with a delayed release producing a fricative sound: [c] = [ts], [C] = [tS], etc.
Stop coarticulation: a stop is produced simultaneously with another stop, e.g. /kp)/ (found extensively in some Bantu language groups), /tk/ (some South American languages) and /pt/ (the Northwest Caucasian languages); often, these are written with a tie bar over the two fused sounds.
