Alveolar consonants (; UK also ) are
articulated with the tongue against or close to the superior
alveolar ridge

Postalveolar (post-alveolar) consonants are consonants articulated with the tongue near or touching the ''back'' of the alveolar ridge. Articulation is farther back in the mouth than the alveolar consonants, which are at the ridge itself, but n ...

Extended IPA may be used: , ''etc.'', though that could also mean extra-retracted. The letters are frequently called 'alveolar', and the language examples below are all alveolar sounds.
(The Extended IPA diacritic was devised for
speech pathology and is frequently used to mean "alveolarized", as in the labioalveolar sounds , where the lower lip contacts the alveolar ridge.)
In IPA
Alveolar consonants are transcribed in the IPA as follows:
Lack of alveolars
There are no languages that have no alveolars at all. The alveolar or dental consonants and are, along with , the most common consonants in human languages.

In labioalveolars, the lower lip contacts the alveolar ridge. Such sounds are typically the result of a severe overbite. In the
