The voiced dental, alveolar, and postalveolar lateral approximants are a type of

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 ...

voiceless alveolar lateral fricative .
In a number of languages, including most varieties of English, the phoneme becomes
velarized ("
dark ''l''") in certain contexts. By contrast, the non-velarized form is the "clear ''l''" (also known as: "light ''l''"), which occurs before and between vowels in certain English standards. Some languages have only clear ''l''. Others may not have a clear ''l'' at all, or have them only before

Occurrence
Languages may have clear apical or laminal alveolars, laminal denti-alveolars (such as French), or true dentals, which are uncommon. Laminal denti-alveolars tend to occur in
continental European languages. However, a true dental generally occurs
allophonically before in languages that have it, as in English ''health''.
