Voiceless dental and alveolar lateral fricatives
A 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 [ɬ]. The symbol [ɬ] is called "belted l" and is distinct from "l with tilde", [ɫ], which transcribes a different sound – the velarized (or pharynɡealized) alveolar lateral approximant, often called "dark L".
A voiceless alveolar lateral approximant is transcribed in IPA as ⟨l̥⟩. In Sino-Tibetan languages, Ladefoged & Maddieson (1996) argue that Burmese and Standard Tibetan have voiceless lateral approximants [l̥] and Li Fang-Kuei & William Baxter contrast apophonically the voiceless alveolar lateral approximant from its voiced counterpart in the reconstruction of Old Chinese. A voiceless dental or alveolar lateral approximant is found as an allophone of its voiced counterpart in British English and Philadelphia English after voiceless coronal and labial stops, and it is velarized before back vowels; the allophone of /l/ after /k/ is most commonly as a voiceless velar lateral approximant.[failed verification] See English phonology.
Features of a voiceless alveolar lateral fricative:
Lateral fricatives are common among indigenous languages of western North America, such as Nahuatl, Tlingit 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.
Lateral fricatives are rare in European languages outside the Caucasus, but it is found notably in Welsh, in which it is written ⟨ll⟩. Several Welsh names beginning with this sound (Llwyd [ɬʊɨd], Llywelyn [ɬəˈwɛlɨn]) have been borrowed into English and then retain the Welsh ⟨ll⟩ spelling but are pronounced with an /l/ (Lloyd, Llewellyn), or they are substituted with ⟨fl⟩ (pronounced /fl/) (Floyd, Fluellen). It was also found in certain dialects of Lithuanian Yiddish.
Modern South Arabian languages are known for their apparent archaic Semitic features, especially in their system of phonology. For example, they preserve the lateral fricatives *ś [ɬ] and *ṣ́/ḏ̣ [ɬʼ] of Proto-Semitic. Except for the Modern South Arabian languages, every other extant Semitic language has merged Proto-Semitic *s2 [ɬ] into one of the two other plain sibilants.
The phoneme /ɬ/ was reconstructed for the most ancient Hebrew speech of the Ancient Israelites. The orthography of Biblical Hebrew, however, did not directly indicate it. It is, however, attested by later developments: /ɬ/ was written with ⟨ש⟩, but the letter was also used for the sound /ʃ/. Later, /ɬ/ merged with /s/, a sound that had been written only with ⟨ס⟩. As a result, three etymologically distinct modern Hebrew phonemes can be distinguished: /s/ written ⟨ס⟩, /ʃ/ written ⟨ש⟩ (with later niqqud pointing שׁ), and /s/ evolving from /ɬ/ and written ⟨ש⟩ (with later niqqud pointing שׂ). The specific pronunciation of ⟨ש⟩ evolving to /s/ from [ɬ] is known based on comparative evidence since /ɬ/ 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 /ɬ/ began to merge with /s/ in Late Biblical Hebrew, as is indicated by interchange of orthographic ⟨ש⟩ and ⟨ס⟩, possibly under the influence of Aramaic, and became the rule in Mishnaic Hebrew. In all Jewish reading traditions, /ɬ/ and /s/ have merged completely, but in Samaritan Hebrew /ɬ/ has instead merged into /ʃ/.
