Voiced dental and alveolar lateral fricatives
|Voiced alveolar lateral fricative|
The voiced alveolar lateral fricative is a type of consonantal sound, used in some spoken languages. The symbol in the International Phonetic Alphabet that represents voiced dental, alveolar, and postalveolar lateral fricatives is ⟨ɮ⟩ (sometimes referred to as lezh), and the equivalent X-SAMPA symbol is
Features of the voiced alveolar lateral fricative:
- Its manner of articulation is fricative, which means it is produced by constricting air flow through a narrow channel at the place of articulation, causing turbulence.
- Its place of articulation is 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.
- Its phonation is voiced, which means the vocal cords vibrate during the articulation.
- It is an oral consonant, which means air is allowed to escape through the mouth only.
- It is a lateral consonant, which means it is produced by directing the airstream over the sides of the tongue, rather than down the middle.
- The airstream mechanism is pulmonic, which means it is articulated by pushing air solely with the intercostal muscles and diaphragm, as in most sounds.
Dental or denti-alveolar
|Amis||Kangko accent||Interdental [ɮ̪͆]|
|Adyghe||къалэ||[qaːɮa] (help·info)||'town'||Can also be pronounced as [l]|
|Bura||[example needed]||Contrasts with [ɬ] and [ʎ̝̊].|
|Kabardian||блы||[bɮə] (help·info)||'seven'||Can also be pronounced as [l]|
|Mongolian||монгол||[mɔɴɢɔ̆ɮ]||'Mongol'||Sometimes realized as [ɬ]|
|Zulu||ukudla||[úɠù:ɮá]||'to eat'||Contrasts with both [ɬ] and [l]; realised as [dɮ] after nasals|
In addition, a pharyngealized voiced alveolar lateral fricative [ɮˤ] (help·info) is reconstructed to be the ancient Classical Arabic pronunciation of Ḍād; the letter is now pronounced in Modern Standard Arabic as a pharyngealized voiced coronal stop, as alveolar [dˤ] or denti-alveolar [d̪ˤ].
In 1938, a symbol shaped similarly to heng ⟨ꜧ⟩ was approved as the official IPA symbol for the voiced alveolar lateral fricative, replacing ⟨ɮ⟩. It was suggested at the same time, however, that a compromise shaped like something between the two may also be used at the author's discretion. It was this compromise version that was included in the 1949 Principles of the International Phonetic Association and the subsequent IPA charts, until it was replaced again by ⟨ɮ⟩ at the 1989 Kiel Convention. Despite the Association's prescription, ⟨ɮ⟩ is nonetheless seen in literature from the 1960s to the 1980s.
