The voiceless alveolar fricatives are a type of fricative consonant pronounced with the tip or blade of the tongue against the alveolar ridge (gum line) just behind the teeth. This refers to a class of sounds, not a single sound. There are at least six types with significant perceptual differences:
*The voiceless alveolar sibilant (the standard symbol in the International Phonetic Alphabet or IPA) has a strong hissing sound, as the ''s'' in English ''sink''. It is one of the most common sounds in the world.
*The voiceless denti-alveolar sibilant (an ''ad hoc'' notation using IPA conventions), also called apico-dental, has a weaker lisping sound like English ''th'' in ''thin''. It occurs in Spanish dialects in southern Spain (eastern Andalusia).
*The voiceless alveolar retracted sibilant ">Voiceless alveolar fricative#Voiceless alveolar retracted sibilant"> and the subform apico-alveolar , or called grave, has a weak hushing sound reminiscent of fricatives. It is used in the languages of northern Iberia, like Asturleonese, Basque, Peninsular Spanish (excluding parts of Andalusia), Catalan, Galician, and Northern European Portuguese. A similar retracted sibilant form is also used in Dutch, Icelandic, some southern dialects of Swedish, Finnish, and Greek. The retracted "S" is also used in Amerindian languages such as Muscogee, Garifuna, and many varieties of Quechua. It was supposedly the standard sound of s in Classical Latin. Its sound is between and [].
*The Voiceless alveolar fricative#Voiceless alveolar non-sibilant fricative, voiceless alveolar non-sibilant fricative or , using the alveolar diacritic from the Extended IPA, is similar to the ''th'' in English ''thin''. It occurs in Icelandic as well as an intervocalic and word-final allophone of English in dialects such as Hiberno-English and Scouse.
*The voiceless alveolar lateral fricative sounds like a voiceless, strongly articulated version of English ''l'' (somewhat like what the English cluster ''**hl'' would sound like) and is written as ''ll'' in Welsh.

The first three types are sibilants, meaning that they are made by directing a stream of air with the tongue towards the teeth and have a piercing, perceptually prominent sound.

Voiceless alveolar sibilant

The voiceless alveolar sibilant is a common consonant sound in vocal languages. It is the sound in English words such as ''sea'' and ''pass'', and is represented in the International Phonetic Alphabet with . It has a characteristic high-pitched, highly perceptible hissing sound. For this reason, it is often used to get someone's attention, using a call often written as or .

The voiceless alveolar sibilant is one of the most common sounds cross-linguistically. If a language has fricatives, it will most likely have . However, some languages have a related sibilant sound, such as , but no . In addition, sibilants are absent from most Australian Aboriginal languages, in which fricatives are rare; however, does occur in Kalaw Lagaw Ya.

Comparison between English and Spanish

The term "voiceless alveolar sibilant" is potentially ambiguous in that it can refer to at least two different sounds. Various languages of northern Iberia (e.g., Astur-Leonese, Catalan, Basque, Galician, Portuguese and Spanish) have a so-called " voiceless apico-alveolar sibilant" that lacks the strong hissing of the described in this article but has a duller, more "grave" sound quality somewhat reminiscent of a voiceless retroflex sibilant. Basque, Mirandese and some Portuguese dialects in northeast Portugal (as well as medieval Spanish and Portuguese in general) have both types of sounds in the same language.

There is no general agreement about what actual feature distinguishes these sounds. Spanish phoneticians normally describe the difference as (for the northern Iberian sound) vs. (for the more common sound), but Ladefoged and Maddieson claim that English can be pronounced apically, which is evidently not the same as the apical sibilant of Iberian Spanish and Basque. Also, Adams asserts that many dialects of Modern Greek have a laminal sibilant with a sound quality similar to the "apico-alveolar" sibilant of northern Iberia.

Some authors have instead suggested that the difference lies in tongue shape. Adams describes the northern Iberian sibilant as "retracted". Ladefoged and Maddieson appear to characterize the more common hissing variant as ', and some phoneticians (such as J. Catford) have characterized it as '' sulcal'' (which is more or less a synonym of "grooved"), but in both cases, there is some doubt about whether all and only the "hissing" sounds actually have a "grooved" or "sulcal" tongue shape.

Features

Features of the voiceless alveolar sibilant:

* There are at least three specific variants of :
** Dentalized laminal alveolar (commonly called "dental"), which means it is articulated with the tongue blade very close to the upper front teeth, with the tongue tip resting behind lower front teeth. The hissing effect in this variety of is very strong., cited in
** Non-retracted 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''. According to about half of English speakers use a non-retracted apical articulation.
** Retracted alveolar, which means it is articulated with either the tip or the blade of the tongue slightly behind the alveolar ridge, termed respectively ''apical'' and ''laminal''. Acoustically, it is close to laminal or (to a lesser extent) .

Voiceless apico-alveolar sibilant

The voiceless alveolar retracted sibilant (commonly termed the voiceless apico-alveolar sibilant) is a fricative that is articulated with the tongue in a hollow shape, usually with the tip of the tongue (apex) against the alveolar ridge. It is a sibilant sound and is found most notably in a number of languages in a linguistic area covering northern and central Iberia. It is most well known from its occurrence in the Spanish of this area. In the Middle Ages, it occurred in a wider area, covering Romance languages spoken throughout France, Portugal, and Spain, as well as Old High German and Middle High German.

Occurrence in Europe

Modern

In Romance languages, it occurs as the normal voiceless alveolar sibilant in Astur-Leonese, Castilian Spanish, Catalan, Galician, northern European Portuguese, and some Occitan dialects. It also occurs in Basque and Mirandese, where it is opposed to a different voiceless alveolar sibilant, the more common ; the same distinction occurs in a few dialects of northeastern Portuguese. Outside this area, it also occurs in a few dialects of Latin American Spanish (e.g. Antioqueño and Pastuso, in Colombia).

Amongst Germanic languages, it occurs in Dutch (and closely related Low German), Icelandic, many dialects in Scandinavia, and working-class Glaswegian English.

It also occurs in Modern Greek (with a articulation), as well as the Baltic languages.

There is no single IPA symbol used for this sound. The symbol is often used, with a diacritic indicating an pronunciation. However, that is potentially problematic in that not all alveolar retracted sibilants are apical (see below), and not all apical alveolar sibilants are retracted. The ad hoc non-IPA symbols and are often used in the linguistic literature even when IPA symbols are used for other sounds, but is a common transcription of the retroflex sibilant .

Medieval

In medieval times, it occurred in a wider area, including the Romance languages spoken in most or all of France and Iberia (Old Spanish, Galician-Portuguese, Catalan, French, etc.), as well as in the Old and Middle High German of central and southern Germany, and most likely Northern Germany as well. In all of these languages, the retracted "apico-alveolar" sibilant was opposed to a non-retracted sibilant much like modern English , and in many of them, both voiceless and voiced versions of both sounds occurred. A solid type of evidence consists of different spellings used for two different sibilants: in general, the retracted "apico-alveolar" variants were written or , while the non-retracted variants were written , or . In the Romance languages, the retracted sibilants derived from Latin , or , while the non-retracted sibilants derived from earlier affricates and , which in turn derived from palatalized or . The situation was similar in High German, where the retracted sibilants derived largely from Proto-Germanic , while the non-retracted sibilants derived from instances of Proto-Germanic that were shifted by the High German sound shift. Minimal pairs were common in all languages. Examples in Middle High German, for example, were "to know" (Old English , cf. "to wit") vs. "known" (Old English ), and "white" (Old English ) vs. "way" (Old English , cf. "-wise").

Description of the retracted sibilant

Often, to speakers of languages or dialects that do not have the sound, it is said to have a "whistling" quality, and to sound similar to palato-alveolar . For this reason, when borrowed into such languages or represented with non-Latin characters, it is often replaced with . This occurred, for example, in English borrowings from Old French have a very similar-sounding sibilant that is pronounced with a articulation.

Loss of the voiceless alveolar sibilant

This distinction has since vanished from most of the languages that once had it in medieval times.
* In most dialects of Spanish, the four alveolar sibilants have merged into the non-retracted (). However, in the Spanish of central and northern Spain, the non-retracted was fronted to after merging with non-retracted , while the retracted remains (). ''Distinción'' is also preserved in Spanish orthography on both sides of the Atlantic.
* In French and most dialects of Portuguese, the four alveolar sibilants have merged into non-retracted and , while in European Portuguese, most other Old World Portuguese variants and some recently European-influenced dialects of Brazil all instances of coda , voiced before voiced consonants, were backed to , while in most of Brazilian Portuguese this phenomenon is much rarer, being essentially absent in the dialects that had a greater indigenous and/or non-Portuguese European influence.
* In the remaining dialects of Portuguese, found in northern Portugal, they merged into the retracted , or, as in Mirandese (which is, however, not a Portuguese dialect, but belongs to Asturian-Leonese), conserved the medieval distinction.
* In German, was early on voiced to in prevocalic position. This sound was then fronted to , but did not merge with any other sound (except that it was later re-devoiced in some southern dialects). In pre-consonantal and final position, merged with either or . The rules for these mergers differ between dialects. In Standard German, is used stem-initially and sporadically after ‹r›. Especially in Alemannic, every pre-consonantal became .

Loss-causing events

Those languages in which the sound occurs typically did not have a phonological process from which either or appeared, two similar sounds with which ⟨s̺⟩ was eventually confused. In general, older European languages only had a single pronunciation of s.

In Romance languages, was reached from -ti-, -ci-, -ce- (, , ) clusters that eventually became , , and later , , (as in Latin ''fortia'' "force", ''civitas'' "city", ''centum'' "hundred"), while was reached:
* From a or cluster in southern Romance, as in Latin ''miscere'' > Portuguese ''mexer'' "to move", Latin ''fluxus'' > Spanish ''flojo'' "lax", Latin ''crescere'' > Italian ''crescere'' "grow", with a different pronunciation.
* from a deaffricated in Northern France and southern-central Portugal, as in French ''chat'' "cat", Portuguese ''achar'' "find".
In High German, was reached through a > > process, as in German ''Wasser'' compared to English ''water''. In English, the same process of Romance > occurred in Norman-imported words, accounting for modern homophones ''sell'' and ''cell''. was also reached from a -sk- cluster reduction as in Romance, e.g. Old English spelling ''asc'' for modern ''ash'', German ''schiff'' and English ''ship'' compared to Danish ''skib''.

Exceptions

Standard Modern Greek, which has apical , lacked both processes.

The Germanic-speaking regions that did not have either phenomenon have normally preserved the apical , that is, Icelandic, Dutch and many Scandinavian lects. It is also found in a minority of Low German dialects.

The main Romance language to preserve the sound, Castilian Spanish, is exceptional in that it had both events that produced and , and preserved the apical S at the expense of both, that were shifted farther away. Galician, Catalan and Ladino changed only .

Reach in ancient times

Because of the widespread medieval distribution, it has been speculated that retracted was the normal pronunciation in spoken Latin. Certain borrowings suggest that it was not far off from the sh-sound , e.g. Aramaic ''Jeshua'' > Greek ''Ἰησοῦς (Iēsoûs)'' > Latin ''Jesus'', Hebrew ''Shabbat'' > Latin ''sabbatum''; but this could also be explained by the lack of a better sound in Latin to represent Semitic ''š''. It equally well could have been an areal feature inherited from the prehistoric languages of Western Europe, as evidenced by its occurrence in modern Basque.

For the same reasons, it can be speculated that retracted was the pronunciation of Proto-Germanic s. Its presence in many branches of Indo-European and its presence particularly in the more conservative languages inside each branch (e.g. Icelandic, Spanish), as well as being found in disparate areas, such as the Baltic languages and Greece, suggests it could have ultimately been the main allophone of Proto-Indo-European s, known for ranging from to as far as .

, but not , was developed in Italian. However, where Spanish and Catalan have apical , Italian uses the same laminal that occurs in standard forms of English: evidence, it could be argued, that S was not pronounced apically in Latin. But Neapolitan has a medieval S becoming either or depending on context, much as in European Portuguese, which could attest to the previous existence of in the Italian Peninsula. The Italian pronunciation as laminal S could also be explained by the presence of but not , thus moving the pronunciation of to the front of the mouth in an attempt to better differentiate between the two sounds.

Voiceless lamino-dental sibilant

A voiceless laminal dental or dentialveolar sibilant contrasts with a voiceless apical alveolar or post-alveolar sibilant in Basque and several languages of California, including Luiseño of the Uto-Aztecan family and Kumeyaay of the Yuman family.

Voiceless alveolar non-sibilant fricative

The voiceless alveolar non-sibilant fricative (also known as a "slit" fricative) is a consonantal sound. As the International Phonetic Alphabet does not have separate symbols for the alveolar consonants (the same symbol is used for all coronal places of articulation that are not palatalized), this sound is usually transcribed , occasionally ( retracted or alveolarized , respectively), (constricted voiceless ), or (lowered ).

Some scholars also posit the voiceless alveolar approximant distinct from the fricative. The approximant may be represented in the IPA as .

Few languages also have the voiceless alveolar tapped fricative, which is simply a very brief apical alveolar non-sibilant fricative, with the tongue making the gesture for a tapped stop but not making full contact. This can be indicated in the IPA with the lowering diacritic to show full occlusion did not occur.

Tapped fricatives are occasionally reported in the literature, though these claims are not generally independently confirmed and so remain dubious.

''Flapped'' fricatives are theoretically possible but are not attested.

Features

However, it does not have the grooved tongue and directed airflow, or the high frequencies, of a sibilant.

Occurrence

Voiceless lateral-median fricative

The voiceless alveolar non-sibilant fricative (also known as a "lisp" fricative) is a consonantal sound. Consonants is pronounced with simultaneous lateral and central airflow.

Features

However, it does not have the grooved tongue and directed airflow, or the high frequencies, of a sibilant.
