:''Not to be confused with the alveolar clicks. Unicode uses the obsolete description "alveolar click" for the palatal-click letter .'' The palatal or palato-alveolar clicks are a family of click consonants found only in Africa. The tongue is nearly flat, and is pulled back rather than down as in the postalveolar clicks, making a sharper sound than those consonants. The tongue makes an extremely broad contact across the roof of the mouth, making a determination of their place of articulation difficult, but Ladefoged & Traill (1984:18) find that the primary place of articulation is the palate, and say that "there is no doubt that should be described as a palatal sound". The symbol in the International Phonetic Alphabet that represents the place of articulation of these sounds is , a double-barred pipe. An older variant, the double-barred esh, , is sometimes seen. This may be combined with a second letter or a diacritic to indicate the manner of articulation, though this is commonly omitted for tenuis clicks. In the orthographies of individual languages, palatal clicks may be written either with digraphs based on the pipe letter of the IPA, or using the Latin alphabet. Nama and most Saan languages use the former. Conventions for the latter include multigraphs based on in Juǀʼhoansi (1987 orthography) and originally in Naro, the latter since changed to , and on . In the 19th century, was sometimes used (see click letters); this might be the source of the Doke letter for the voiceless palatal click, , apparently a ''v'' over-struck with a pipe. ==Features== Features of palato-alveolar clicks: *The forward place of articulation is broad, with the tongue flat against the roof of the mouth from the alveolar ridge to the palate. The release is a sharp, plosive sound. 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「palatal clicks」の詳細全文を読む スポンサード リンク
