Approximants are speech sounds that could be regarded as intermediate between vowels and typical consonants. In the articulation of approximants, articulatory organs produce a narrowing of the vocal tract, but leave enough space for air to flow without much audible turbulence. Approximants are therefore more open than fricatives. This class of sounds includes lateral approximants like [l], as in lip, and approximants like [j] and [w] in yes and well which correspond closely to vowels and semivowels.

Palatal approximants correspond to front vowels, velar approximants to back vowels, and labialized approximants to rounded vowels. They are typically briefer and closer than the corresponding vowels.

When emphasized, approximants may be slightly fricated (that is, the airstream may become slightly turbulent), which is reminiscent of fricatives. Examples are the y of English yes! (especially when lengthened) and the "weak" allophones of Spanish b, d, g, which are often transcribed as fricatives (often due perhaps to a lack of dedicated approximant symbols). However, such frication is generally slight and intermittent, unlike the strong turbulence of fricative consonants.

This confusion is also common with voiceless approximants, which necessarily have a certain amount of fricative-like noise. For example, the voiceless labialized velar approximant [ʍ] has traditionally been called a fricative. Tibetan has a voiceless lateral approximant, [l̥], and Welsh has a voiceless lateral fricative [ɬ], but the distinction is not always clear from descriptions of these languages.

For places of articulation further back in the mouth, languages do not contrast voiced fricatives and approximants. Therefore the IPA allows the symbols for the voiced fricatives to double for the central approximants, with or without a lowering diacritic.

Occasionally the glottal "fricatives" are called approximants, since [h] typically has no more frication than voiceless approximants, but they are often phonations of the glottis without any accompanying manner or place of articulation.

Although many languages have central vowels [ɨ, ʉ] which lie between back/velar [ɯ, u] and front/palatal [i, y], there are no confirmed reports of corresponding approximants. However, Mapudungun may be a possibility: It has three high vowel sounds, /i/, /u/, /ɨ/, written "i", "u", "ü", and three corresponding consonants, written "y", "w", "q". The first two are clearly /j/ and /w/. The "q" is often described as a voiced unrounded velar fricative, but some texts note a correspondence between "q" and /ɨ/ that is parallel to /j/-/i/ and /w/-/u/. An example is liq /'liɣ/ "white".^[1]
