The voiceless alveolar lateral fricative is a type of consonantal sound, used in some spoken languages. The symbol in the International Phonetic Alphabet that represents voiceless dental, alveolar, and postalveolar lateral fricatives is , and the equivalent X-SAMPA symbol is K.

The symbol  is called "belted l" and is distinct from "l with tilde", , which transcribes a different sound - the velarized (or pharynɡealized) alveolar lateral approximant, often called "dark L".

Features 
Features of the voiceless alveolar lateral fricative:

Occurrence 
The sound is fairly common among indigenous languages of the Americas, such as Nahuatl and Navajo, and in North Caucasian languages, such as Avar. It is also found in African languages, such as Zulu, and Asian languages, such as Chukchi, some Yue dialects like Taishanese, the Hlai languages of Hainan, and several Formosan languages and dialects in Taiwan.

The sound is rare in European languages outside the Caucasus, but it is found notably in Welsh in which it is written . Several Welsh names beginning with this sound (Llwyd , Llywelyn ) have been borrowed into English and then retain the Welsh  spelling but are pronounced with an  (Lloyd, Llewellyn), or they are substituted with  (pronounced ) (Floyd, Fluellen). It was also found in certain dialects of Lithuanian Yiddish.

The phoneme  was also found in the most ancient Hebrew speech of the Ancient Israelites. The orthography of Biblical Hebrew, however, did not directly indicate the phoneme since it and several other phonemes of Ancient Hebrew did not have a grapheme of their own. The phoneme, however, is clearly attested by later developments:  was written with , but the letter was also used for the sound . Later,  merged with , a sound that had been written only with . As a result, three etymologically distinct modern Hebrew phonemes can be distinguished:  written ,  written  (with later niqqud pointing שׁ), and  evolving from  and written  (with later niqqud pointing שׂ). The specific pronunciation of  evolving to  from  is known based on comparative evidence since  is the corresponding Proto-Semitic phoneme and is still attested in Modern South Arabian languages, and early borrowings indicate it from Ancient Hebrew (e.g. balsam < Greek balsamon < Hebrew baśam). The phoneme  began to merge with  in Late Biblical Hebrew, as is indicated by interchange of orthographic  and , possibly under the influence of Aramaic, and became the rule in Mishnaic Hebrew. In all Jewish reading traditions,  and  have merged completely, but in Samaritan Hebrew  has instead merged into .

The  sound is also found in two of the constructed languages invented by J. R. R. Tolkien, Sindarin (inspired by Welsh) and Quenya (inspired by Finnish, Ancient Greek, and Latin). In Sindarin, it is written as  initially and  medially and finally, and in Quenya, it appears only initially and is written .

Dental or denti-alveolar

Alveolar

Semitic languages 
The sound is conjectured as a phoneme for Proto-Semitic language, usually transcribed as ; it has evolved into Arabic , Hebrew :

Among Semitic languages, the sound still exists in contemporary Soqotri and Mehri. In Ge'ez, it is written with the letter Śawt.

Capital letter

Since the IPA letter "ɬ" has been adopted into the standard orthographies for many native North American languages, a capital letter L with belt "Ɬ" was requested by academics and added to the Unicode Standard version 7.0 in 2014 at U+A7AD.
