Dental and alveolar lateral flaps
|Alveolar lateral flap|
source · help
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.
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 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 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.
