Phonetic symbol for the linguo-labial central approximant.
Phonetic symbol for the labial central approximant.

Approximants are speech sounds which are pronounced with a stricture of open approximation. This means that the active articulator approaches the passive articulator but there remains a wide gap between both so that the airflow does not cause an audible hiss. Approximants can have a central or a lateral airflow. In central approximants, the air flows along a central path over the tongue. In lateral approximants the tongue touches the roof of the mouth in the central area and the air flows around this obstacle so that the airflow is lateral.

 

The IPA distinguishes 5 symbols for the central approximants at the following places of articulation: labio-dental, alveolar, retroflex, palatal and velar. In addition, it provides 4 symbols for lateral approximants: alveolar, retroflex, palatal and velar. Additional symbols for the central approximants can be derived from the fricative symbol at the corresponding place of articulation by adding a diacritic denoting a more open degree of approximation: this can be seen above for e.g. the lingo-labial and dental approximants.

Approximants are typically voiced, but voiceless approximants do occur. Laai reportedly has several voiceless approximants which contrast phonemically with voiced approximants. Approximants can also be
