assibilation

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 Mashreqi varieties of Arabic (particularly Levantine and Egyptian) 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). 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 as ''isi-'', Sotho as ''se-'', Venda as ''tshi-'' and Shona as ''chi-''.

Finnic languages

Finnic languages (Finnish, Estonian and their closest relatives) had changed to . The alternation can be seen in dialectal and inflected word forms: Finnish "to deny" → ~ "s/he denied"; "water" vs. "as water".

An intermediate stage is preserved in South Estonian in certain cases: ''tsiga'' "pig", vs. Finnish , Standard (North) Estonian .

Germanic languages

In the High German consonant shift, voiceless stops spirantized to at the end of a syllable. The shift of to (as in English ''water'', German ) 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:

Greek

In Proto-Greek, the earlier combinations ''*ty'', ''*t^hy'' 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:

* -> PG > Homeric > Attic "this much" (Latin )
* > PG > Homeric > Attic "middle" (Latin )

Some Greek dialects later underwent yet another round of assibilation. shifted to finally in Attic and Ionic but not in Doric.
*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 was pronounced (for example, was pronounced and ). However, in Vulgar Latin, it assibilated to , which can still be seen in Italian: .

In French, lenition then gave (like )., which was further palatalized in the English derived words to (like ''attention'' ).

Most dialects of Quebec French apply a more recent assibilation to all dental plosive consonants immediately before high front vowels and associated semivowels, so that the sequences become pronounced respectively.

Assibilation can occur in some varieties of Spanish 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.
