The alveolar lateral flap is a type of consonantal sound, used in some spoken languages. The symbol in the International Phonetic Alphabet that represents this sound is ɺ, a fusion of a rotated lowercase letter r with a letter l.

Some languages that are described as having a lateral flap actually have a flap that is indeterminate with respect to centrality, and may surface as either central or lateral, either in free variation or allophonically depending on surrounding vowels and consonants.[1]

Features

Features of the alveolar lateral flap:

  • Its manner of articulation is flap, which means it is produced with a single contraction of the muscles so that one articulator (usually the tongue) is thrown against another.
  • 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.
