In linguistics, assibilation is a sound change resulting in a sibilant consonant. It is a form of spirantization and is commonly the final phase of palatalization.
Arabic
A characteristic of
varieties of Arabic (particularly
Levantine Arabic and
Egyptian Arabic) is to assibilate the interdental consonants of Modern Standard Arabic (MSA) in certain contexts (defined more culturally than phonotactically). Thus, , pronounced in MSA, becomes (as MSA → Levantine "culture"); , pronounced in MSA, becomes (as MSA → Levantine "guilt"); and , pronounced in MSA, becomes (as MSA → Levantine "lucky").
Diachronically, the phoneme represented by the letter has, in some dialects, experienced assibilation as well. The pronunciation in Classical Arabic is reconstructed to have been or (or perhaps both dialectically); it is cognate to in most other Semitic languages, and it is understood to be derived from that sound in Proto-Semitic. It has experienced extensive change in pronunciation over the centuries and is pronounced at least six different ways across the assorted varieties of Arabic. A common one is , the result of a process of palatalization starting with Proto-West Semitic , then or , then (a pronunciation still current) and finally (in Levantine and non-Algerian Maghrebi Arabic). The last pronunciation is considered acceptable for use in MSA, along with and .
Bantu languages
In the history of several Bantu groups, including the Southern Bantu languages, the
Proto-Bantu consonant
*k was palatalised before a close or near-close vowel. Thus, the class 7 noun prefix
*kɪ̀- appears in e.g.
Zulu language as
i si-,
Sotho language as
s e- , Venda language as tshi- and
Shona language as
chi-.
Finnic languages
Finnic languages (
Finnish language, Estonian and their closest relatives) had changed to . The alternation can be seen in dialectal and inflected word forms: Finnish kieltää "to deny" → kielti ~ kielsi "s/he denied"; vesi "water" vs. vete-nä "as water".
An intermediate stage is preserved in South Estonian in certain cases: tsiga "pig", vs. Finnish sika, Standard (North) Estonian siga.
Germanic languages
In the High German consonant shift, voiceless stops
spirantization to at the
syllable coda of a
syllable. The shift of to (as in English
water,
German language Wasser) is assibilation.
Assibilation occurs without palatalization for some speakers of African American Vernacular English in which is alveolarized to when it occurs at the end of a syllable and within a word before another consonant, leading to such pronunciations as the following:[ Phonological Features of African American Vernacular English]
The slang in African-American Vernacular English popularized to American English by Ty Dolla Sign's Zaddy may have been formed by analysis of an assibilated /d/ phoneme preceding /æ/ in the first syllable of by the subject girl in question who "wanna come to California / brown skin, from Miami".[Jones, Taylor (Apr 14, 2022).

Greek
In Proto-Greek, the earlier combinations
*ty,
*thy and
*dy assibilated to become alveolar affricates,
*ts and
*dz, in what is called the first palatalization. Later, a second round of palatalization occurred and initially produced geminate palatal
*ťť and
*ďď from various consonants, followed by
*y. The former was depalatalised to plain geminate
tt in some dialects and was assibilated to
ss in others. The latter evolved into an affricate
dz in all Greek dialects:
-
tot-yos -> PG > Homeric Greek > Attic Greek "this much" (Latin tot)
-
medʰ-yos > PG > Homeric > Attic "middle" (Latin medius)
Some Greek dialects later underwent yet another round of assibilation. *ti shifted to finally in Attic and Ionic Greek[Smyth. par. 115: -ti > -si.] but not in Doric Greek.[Smyth. note 115: Doric -ti.]
-
Doric – Attic-Ionic "he/she places"
Romance languages
The word "assibilation" itself contains an example of the phenomenon, as it is pronounced . The
Classical Latin -tio was pronounced (for example, assibilatio was pronounced and attentio ). However, in
Vulgar Latin, it assibilated to , which can still be seen in
Italian language: attenzione.
In French language, lenition then gave (like attention )., which was further palatalized in the English language derived words to (like attention ).
Most dialects of Quebec French apply a more recent assibilation to all dental consonant plosive consonants immediately before high vowel and associated , so that the sequences become pronounced respectively.
Assibilation can occur in some varieties of Spanish language such as in Ecuador and Mexico. It is closely related to the phonetic term sibilation.
Slavic languages
Palatalization effects were widespread in the history of
Proto-Slavic. In the first palatalization, various consonants were converted into postalveolar fricatives and affricates, while in the second and third palatalizations, the results were alveolar.
Some Slavic languages underwent yet another round of palatalisation. In Polish, in particular, dental consonants became alveolo-palatal fricatives and affricates when followed by a front vowel.
Reverse process
In Gorontalo, the reverse of assibilation occurred, when the instances of
*s became
t (
*siku →
ti'u "elbow"). However, its sister language Mongondow still partially retains it (
siku).
