(Redirected from Lateral approximant)
'Laterals' are "L"-like
consonants pronounced with an occlusion made somewhere along the axis of the tongue, while air from the lungs escapes at one side or both sides of the tongue.
Most commonly the tip of the tongue makes contact with the upper teeth (see
dental consonant) or the upper gum (the alveolar ridge) just behind the teeth (see
alveolar consonant). The most common laterals are
approximants and belong to the class of
liquids.
Laterals in various languages
English has one lateral phoneme: the lateral approximant , which in many accents has two
allophones. One, found before vowels as in ''lady'' or ''fly'', is called ''clear l'', pronounced as the
alveolar lateral approximant with a "neutral" position of the body of the tongue. The other variant, so-called ''dark l'' found before consonants or word-finally, as in ''bold'' or ''tell'', is pronounced as the
velarized alveolar lateral approximant with the tongue assuming a spoon-like shape with its back part raised, which gives the sound a - or -like resonance. In some languages, like
Albanian, those two sounds are different phonemes.
East Slavic languages contrast and but do not have a plain [l].
In many British accents (e.g. London English), dark may undergo
vocalization through the reduction and loss of contact between the tip of the tongue the alveolar ridge, becoming a rounded back vowel or glide. This process turns ''tell'' into something like . A similar process happened in
Brazilian Portuguese and in
Old French, resulting in , whence
Modern French ''sauce'' as compared with
Spanish ''salsa''. Also in Polish historical (spelled ''ł'') has become [w].
In central and Venice dialects of
Vèneto intervocalic has turned into a semivocalic , so that the written word ''la bala'' is pronounced .
Many aboriginal
Australian languages have a series of three or four lateral approximants, as do various dialects of
Irish. Rarer lateral consonants include the retroflex laterals that can be found in most
Indic languages and in some
Swedish dialects; and the sound of
Welsh ''ll'', the
voiceless alveolar lateral fricative that is also found in
Zulu and many
Semitic and
Native American languages. In
Adyghe and some
Athapaskan languages like
Hän both voiceless and voiced alveolar lateral fricative occur, but there is no approximant. Many of these languages also have lateral
affricates. Some languages have palatal or velar voiceless lateral fricatives or affricates, such as
Dahalo and
Zulu but the IPA has no symbols for these sounds. However, appropriate symbols are easy to make by adding a lateral-fricative belt to the symbol for the corresponding lateral approximant (see below). Failing that, a devoicing diacritic is added to the approximant.
Tibetan has a voiceless lateral approximant, usually romanized as ''lh'', as in the name
Lhasa.
Japanese has an
alveolar lateral flap and
Pashto has
retroflex one.
Korean has a single phoneme that is realized as either the lateral approximant or the (non-lateral)
alveolar tap , depending on where it occurs.
A large number of lateral
click consonants, 17, occur in
!Xóõ.

Other symbols
The symbol for the voiceless alveolar lateral fricative forms the basis for the occasional ''ad hoc'' symbols for other voiceless lateral fricatives:
retroflex,
palatal,
velar (the latter two only known from affricates):

The symbol for the alveolar lateral flap is the basis for the expected symbol for the
retroflex lateral flap:

Such symbols are rare, but are becoming more common now that font-editing software has become accessible. Note however that since they are not sanctioned by the IPA, there are no
Unicode values for them.
