Avoiceless palato-alveolar fricative orvoiceless domed postalveolar fricative is a type ofconsonantal sound used in manylanguages, including English. In English, it is usually spelled⟨sh⟩, as inship.
Features of the voiceless palato-alveolar fricative:
Itsmanner of articulation issibilantfricative, which means it is generally produced by channeling air flow along agroove in the back of the tongue up to the place of articulation, at which point it is focused against the sharp edge of the nearly clenched teeth, causing high-frequencyturbulence.
Itsphonation is voiceless, which means it is produced without vibrations of the vocal cords. In some languages the vocal cords are actively separated, so it is always voiceless; in others the cords are lax, so that it may take on the voicing of adjacent sounds.
It is anoral consonant, which means that air is not allowed to escape through the nose.
It is acentral consonant, which means it is produced by directing the airstream along the center of the tongue, rather than to the sides.
/ʂ/ and/ɕ/ merge into[ʃ] in these dialects. In standard Polish,/ʃ/ is commonly used to transcribe what actually is a laminalvoiceless retroflex sibilant
In various languages, including English and French, it may have simultaneouslabialization, i.e.[ʃʷ], although this is usually not transcribed.
Classical Latin did not have[ʃ], though it does occur in mostRomance languages. For example,⟨ch⟩ in Frenchchanteur "singer" is pronounced/ʃ/.Chanteur is descended from Latincantare, where⟨c⟩ was pronounced/k/. The⟨sc⟩ in Latinscientia "science" was pronounced/sk/, but has shifted to/ʃ/ in Italianscienza.
Similarly,Proto-Germanic had neither[ʃ] nor[ʂ], yet many of its descendants do. In most cases, this[ʃ] or[ʂ] descends from a Proto-Germanic/sk/. For instance, Proto-Germanic *skipą ("hollow object, water-borne vessel larger than a boat") was pronounced/ˈski.pɑ̃/. The English word "ship"/ʃɪp/ has been pronounced without the/sk/ the longest, the word being descended fromOld English "scip"/ʃip/, which already also had the[ʃ], though the Old English spelling etymologically indicated that the old/sk/ had once been present.
This change took longer to catch on in West Germanic languages other than Old English, though it eventually did. The second West Germanic language to undergo this sound shift wasOld High German. After High German, the shift most likely then occurred in Low Saxon. After Low Saxon, Middle Dutch began the shift, but it stopped shifting once it reached/sx/, and has kept that pronunciation since. Then, most likely through influence from German and Low Saxon,North Frisian experienced the shift.
Then, Swedish quite swiftly underwent the shift, which resulted in the very uncommon[ɧ] phoneme, which, aside from Swedish, is only used inColognian, a variety of High German, though not as a replacement for the standard High German/ʃ/ but a coronalized/ç/. However, the exact realization of Swedish/ɧ/ varies considerably among dialects; for instance, in Northern dialects it tends to be realized as[ʂ]. Seesj-sound for more details. Finally, the last to undergo the shift was Norwegian, in which the result of the shift was[ʃ].
Avoiceless postalveolar non-sibilant fricative is a type of consonantal sound used in some spoken languages. It can be transcribed in the International Phonetic Alphabet as ⟨ɹ̠̊˔⟩ or ⟨ɹ̝̊˗⟩, both of which indicate a[ɹ] that isretracted,raised, andvoiceless.
Itsmanner of articulation isfricative, which means it is produced by constricting air flow through a narrow channel at the place of articulation, causingturbulence. However, it does not have the grooved tongue and directed airflow, or the high frequencies, of a sibilant.
Itsplace of articulation ispostalveolar, which means it is articulated with either the tip or the blade of the tongue behind the alveolar ridge.
Itsphonation is voiceless, which means it is produced without vibrations of the vocal cords. In some languages the vocal cords are actively separated, so it is always voiceless; in others the cords are lax, so that it may take on the voicing of adjacent sounds.
It is anoral consonant, which means that air is not allowed to escape through the nose.
It is acentral consonant, which means it is produced by directing the airstream along the center of the tongue, rather than to the sides.
Only partially devoiced. It is a realization of/r/ after the word-initial fortis plosives/p,k/, unless they are preceded by/s/ within the same syllable.[28] SeeEnglish phonology
^Gussenhoven & Aarts (1999:156). The authors state that/ʃ/ is "pre-palatal, articulated with the blade of the tongue against the post-alveolar place of articulation". This makes it unclear whether this sound is palato-alveolar (somewhat palatalized post-alveolar) or alveolo-palatal (strongly palatalized post-alveolar).
