A central consonant, also known as a median consonant,
is a
consonant
In articulatory phonetics, a consonant is a speech sound that is articulated with complete or partial closure of the vocal tract, except for the h sound, which is pronounced without any stricture in the vocal tract. Examples are and pronou ...
sound that is produced when air flows across the center of the mouth over the tongue. The class contrasts with
lateral consonant
A lateral is a consonant in which the airstream proceeds along one or both of the sides of the tongue, but it is blocked by the tongue from going through the middle of the mouth. An example of a lateral consonant is the English ''L'', as in ''L ...
s, in which air flows over the sides of the tongue rather than down its center.
Examples of central consonants are the
voiced alveolar fricative
The voiced alveolar fricatives are consonantal sounds. The symbol in the International Phonetic Alphabet that represents these sounds depends on whether a sibilant or non-sibilant fricative is being described.

palatal approximant
The voiced palatal approximant is a type of consonant used in many spoken languages. The symbol in the International Phonetic Alphabet that represents this sound is ; the equivalent X-SAMPA symbol is j, and in the Americanist phonetic notation i ...
(the "y" in the English word "yes"). Others are the central fricatives , the central approximants , the trills , and the central flaps .
The term is most relevant for approximants and fricatives (for which there are contrasting lateral and central consonants - e.g. versus and versus ). Stops that have "lateral release" can be written in the

using a superscript symbol, e.g. , or can be implied by a following lateral consonant, e.g. . The labial fricatives often—perhaps usually—have lateral airflow, as occlusion between the teeth and lips blocks the airflow in the center, but nonetheless they are not considered lateral consonants because no language makes a distinction between the two.
In some languages, the centrality of a phoneme may be indeterminate. In Japanese, for example, there is a

Manner of articulation
articulatory phonetics, the manner of articulation is the configuration and interaction of the articulators ( speech organs such as the tongue, lips, and palate) when making a speech sound. One parameter of manner is ''stricture,'' that is, h ...
