Alveolar lateral flap
|Alveolar lateral flap|
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 which are described as having a lateral flap, such as Japanese, actually have a flap which is indeterminate as to centrality, and may surface as either central or lateral, either depending on surrounding vowels or in free variation.
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.
- The airstream mechanism is pulmonic, which means it is articulated by pushing air solely with the lungs and diaphragm, as in most sounds.
