Retroflex lateral approximant

The retroflex lateral approximant is a type of consonantal sound used in some spoken languages. The symbol in the International Phonetic Alphabet that represents this sound is ⟨ɭ⟩, and the equivalent X-SAMPA symbol is l`.

Contents

The retroflex lateral approximant contrasts phonemically with its voiceless counterpart /ɭ̊/ in Iaai and Toda. In both of these languages it also contrasts with more anterior /l̥, l/, which are dental in Iaai and alveolar in Toda.

Features

Features of the retroflex lateral approximant:

  • Its manner of articulation is approximant, which means it is produced by narrowing the vocal tract at the place of articulation, but not enough to produce a turbulent airstream.
  • Its place of articulation is retroflex, which prototypically means it is articulated subapical (with the tip of the tongue curled up), but more generally, it means that it is postalveolar without being palatalized. That is, besides the prototypical sub-apical articulation, the tongue contact can be apical (pointed) or laminal (flat).
  • 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 lungs and diaphragm, as in most sounds.

    • Occurrence

    In the following transcriptions, diacritics may be used to distinguish between apical [ɭ̺] and laminal [ɭ̻].
