approximantits

Approximants are a class of consonants in phonetics that are produced by bringing an articulator close to another without actually creating a full closure or a turbulent airflow. This means they are distinct from both vowels, which have an open vocal tract, and obstruents (stops, fricatives, and affricates), which involve a more significant obstruction or turbulence.

The key characteristic of an approximant is that the airflow is relatively unimpeded, leading to a smooth, non-turbulent sound. This allows for a longer duration than most obstruents and a smoother transition into adjacent vowels. Approximants can be further categorized based on the position of the tongue and the shape of the lips.

Central approximants are produced with the tongue raised in the center of the mouth, while lateral approximants involve air flowing around the sides of the tongue. Common examples of central approximants include the /j/ sound in "yes" and the /w/ sound in "wet." The /l/ sound in "like" is a prime example of a lateral approximant.

Another important distinction is between glides and liquids. Glides, like /j/ and /w/, are often considered to be vowel-like sounds that function as consonants, typically appearing at the beginning of a syllable. Liquids, such as /l/ and /r/, can appear at the beginning or end of a syllable and have more vowel-like qualities in terms of resonance. The phonetic realization of approximants can vary significantly across different languages.
