Notation
The symbol in the International Phonetic Alphabet that represents voiced dental, alveolar, and postalveolar lateral fricatives is ⟨ɮ⟩, sometimes referred to as lezh.
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, ⟨.svg){kind=small}
⟩, 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.[1] Despite the Association's prescription, ⟨ɮ⟩ is nonetheless seen in literature from the 1960s to the 1980s.[2][3][4][5][6]
Related characters
There are several Unicode characters based on lezh (ɮ):
- U+1079E 𐞞 MODIFIER LETTER SMALL LEZH is a superscript IPA letter[7]
- U+1079F 𐞟 MODIFIER LETTER SMALL LEZH WITH RETROFLEX HOOK is a superscript IPA letter[7]
- U+1DF05 𝼅 LATIN SMALL LETTER LEZH WITH RETROFLEX HOOK is an extension to IPA for disordered speech (extIPA)[7][8]
Features
Features of a 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 that air is not allowed to escape through the nose.
- 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.
- Its airstream mechanism is pulmonic, which means it is articulated by pushing air only with the intercostal muscles and abdominal muscles, as in most sounds.

The voiced alveolar lateral–median fricative (also known as a "lisp" fricative) is a consonantal sound pronounced with simultaneous lateral and central airflow.
Features
- 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. However, it does not have the grooved tongue and directed airflow, or the high frequencies, of a sibilant.
- 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 that air is not allowed to escape through the nose.
- It is a median consonant, which means it is produced by directing the airstream down the midline of the tongue, rather than to the sides.
- 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.
- Its airstream mechanism is pulmonic, which means it is articulated by pushing air only with the intercostal muscles and abdominal muscles, as in most sounds.
