The alveolar lateral approximant is a type of consonantal sound used in some spoken languages. The symbol in the International Phonetic Alphabet that represents dental, alveolar, and postalveolar lateral approximants is , and the equivalent X-SAMPA symbol is l. As a sonorant, lateral approximants are nearly always voiced. Voiceless lateral approximants, , are common in Sino-Tibetan languages, but uncommon elsewhere. In such cases, voicing typically starts about halfway through the hold of the consonant. No language contrasts such a sound with a voiceless alveolar lateral fricative . In a number of languages, including most varieties of English, the phoneme becomes velarized in certain contexts, a sound often called "dark l". Some languages, like many North American dialects of English may not have a "clear" at all. ==Features== Features of the voiced alveolar lateral approximant: * There are four specific variants of : * * Dental, which means it is articulated with either the tip or the blade of the tongue at the upper teeth, termed respectively ''apical'' and ''laminal''. * * Denti-alveolar, which means it is articulated with the blade of the tongue at the alveolar ridge, and the tip of the tongue behind upper teeth. * * Alveolar, which means it is articulated with either the tip or the blade of the tongue at the alveolar ridge, termed respectively ''apical'' and ''laminal''. * * Postalveolar, which means it is articulated with either the tip or the blade of the tongue behind the alveolar ridge, termed respectively ''apical'' and ''laminal''. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Dental, alveolar and postalveolar lateral approximants」の詳細全文を読む スポンサード リンク
