Avoiceless retroflex lateral flap is a type ofconsonantal sound, used in somespokenlanguages (as inWahgi).^[1] The implicit symbol for this sound in theInternational Phonetic Alphabet is ⟨𝼈̊⟩.^[2]

Features of a voiceless retroflex lateral flap:

• Itsmanner of articulation istap or flap, which means it is produced with a single contraction of the muscles so that one articulator (usually the tongue) is thrown against another.
• Itsplace of articulation isretroflex, which prototypically means it is articulatedsubapical (with the tip of the tongue curled up), but more generally, it means that it ispostalveolar without beingpalatalized. That is, besides the prototypical subapical articulation, the tongue can beapical (pointed) or, in some fricatives,laminal (flat).
• Itsphonation is voiceless, which means it is produced without vibrations of the vocal cords. In some languages the vocal cords are actively separated, so it is always voiceless; in others the cords are lax, so that it may take on the voicing of adjacent sounds.
• It is anoral consonant, which means that air is not allowed to escape through the nose.
• It is alateral consonant, which means it is produced by directing the airstream over the sides of the tongue, rather than down the middle.
• Itsairstream mechanism ispulmonic, which means it is articulated by pushing air only with theintercostal muscles andabdominal muscles, as in most sounds.
