U+02AD Latin Letter Bidental Percussive

U+02AD was added in Unicode version 3.0 in 1999. It belongs to the block U+0250 to U+02AF IPA Extensions in the U+0000 to U+FFFF Basic Multilingual Plane.

This character is a Lowercase Letter and is mainly used in the Latin script.

The glyph is not a composition. It has no designated width in East Asian texts. In bidirectional text it is written from left to right. When changing direction it is not mirrored. The word that U+02AD forms with similar adjacent characters prevents a line break inside it.

The Wikipedia has the following information about this codepoint:

Bidental consonants are consonants articulated with both the lower and upper teeth. They are normally found only in speech pathology, and are distinct from interdental consonants such as [n̪͆], which involve the tongue articulated between the teeth rather than the teeth themselves. The diacritic for bidental consonants in the extensions to the IPA is the same superscript plus subscript bridge, ◌̪͆. This is used for sounds most commonly found in disordered speech:

  • A bidental percussive, [ʭ] , produced by striking the teeth against each other (gnashing or chattering the teeth).
  • A voiceless bidental fricative, [h̪͆] , a fricative made through clenched teeth with no involvement of the tongue or the lips, a "bidental (consonant) produced by air passing through the closed front teeth".
  • A voiced bidental fricative, [ɦ̪͆], a fricative made through clenched teeth with no involvement of the tongue or the lips and the vocal cords vibrate, due to the sound being voiced.
  • Bidental aspiration of another consonant, e.g. [tʰ̪͆] or [dʱ̪͆].

People with hypoglossia (abnormally small tongue) may use bidental fricatives for target /s/ and /z/.

There is at least one confirmed attestation of a bidental consonant in normal language. The Black Sea sub-dialect of the Shapsug dialect of Adyghe has a voiceless bidental fricative where other dialects have [x], as in хы "six" and дахэ "beautiful". It has been transcribed as x̪͆, reflecting its value in other dialects, but there is no frication at the velum. The teeth themselves are the only constriction: "The lips [are] fully open, the teeth clenched and the tongue flat, the air passing between the teeth; the sound is intermediate between [ʃ] and [f]". This is better transcribed phonetically as h̪͆, since [h] has no place of articulation of its own.
