Palatalization is a historical-linguistic sound change that results in a palatalized articulation of a consonant or, in certain cases, a front vowel. Palatalization involves change in the place or manner of articulation of consonants, or the fronting or raising of vowels. In some cases, palatalization involves assimilation or lenition.
Palatalization is sometimes an example of assimilation. In some cases, it is triggered by a palatal or palatalized consonant or front vowel, but in other cases, it is not conditioned in any way.
Palatalization changes place of articulation or manner of articulation of consonants. It may add palatal secondary articulation or change primary articulation from velar to palatal or alveolar, alveolar to postalveolar.
It may also cause a consonant to change its manner of articulation from stop to affricate or fricative. The change in the manner of articulation is a form of lenition. However, the lenition is frequently accompanied by a change in place of articulation.
Palatalization of velar consonants commonly causes them to front, and apical and coronal consonants are usually raised. In the process, stop consonants are often spirantised except for palatalized labials.
Palatalization, as a sound change, is usually triggered only by mid and close (high) front vowels and the semivowel [j]. The sound that results from palatalization may vary from language to language. For example, palatalization of [t] may produce [t?], [t?], [t?], [ts?], [ts], etc. A change from [t] to [t?] may pass through [t?] as an intermediate state, but there is no requirement for that to happen.
In the Nupe language, /s/ and /z/ are palatalized both before front vowels and /j/, while velars are only palatalized before front vowels. In Ciluba, /j/ palatalizes only a preceding /t/, /s/, /l/ or /n/. In some variants of Ojibwe, velars are palatalized before /j/, but apicals are not. In Indo-Aryan languages, dentals and /r/ are palatalized when occurring in clusters before /j/, but velars are not.
Palatalization sometimes refers to vowel shifts, the fronting of a back vowel or raising of a front vowel. The shifts are sometimes triggered by a nearby palatal or palatalized consonant or by a high front vowel. The Germanic umlaut is a famous example.
A similar change is reconstructed in the history of Old French in which Bartsch's law turned open vowels into [e] or [?] after a palatalized velar consonant. If it was true for all open vowels in Old French, it would explain the palatalization of velar plosives before /a/.
In Russian, the back vowels /u o/ are fronted to central [? ?], and the open vowel /a/ is raised to near-open [æ], near palatalized consonants. The palatalized consonants also factor in how unstressed vowels are reduced.
Palatalization is sometimes unconditioned or spontaneous, not triggered by a palatal or palatalized consonant or front vowel.
In southwestern Romance, clusters of a voiceless obstruent with /l/ were palatalized once or twice. This first palatalization was unconditioned. It resulted in a cluster with a palatal lateral [?], a palatal lateral on its own, or a cluster with a palatal approximant [j]. In a second palatalization, the /k/ was affricated to [t?] or spirantized to [?].
In the Western Romance languages, Latin [kt] was palatalized once or twice. The first palatalization was unconditioned: the /k/ was vocalized to [i?t] or spirantized to [çt]. In a second palatalization, the /t/ was affricated to [t?]:
Old historical splits have frequently drifted since the time they occurred and may be independent of current phonetic palatalization. The lenition tendency of palatalized consonants (by assibilation and deaffrication) is important. According to some analyses, the lenition of the palatalized consonant is still a part of the palatalization process itself.
In Japanese, allophonic palatalization affected the dental plosives /t/ and /d/, turning them into alveolo-palatal affricates [t?] and [d?] before [i], romanized as ?ch? and ?j? respectively. Japanese has, however, recently regained phonetic [ti] and [di] from loanwords, and the originally-allophonic palatalization has thus become lexical. A similar change has also happened in Polish and Belarusian. That would also be true about most dialects of Brazilian Portuguese but for the strong phonotactical resistancy of its native speakers that turn dental plosives into post-alveolar affricates even in loanwords: McDonald's [mki'dõn?wd?(is)].
For example, Votic has undergone such a change historically, *keeli -> t?eeli 'language', but there is currently an additional distinction between palatalized laminal and non-palatalized apical consonants. An extreme example occurs in Spanish, whose palatalized ('soft') g has ended up as [x] from a long process where Latin /?/ became palatalized to  (Late Latin) and then affricated to [d?] (Proto-Romance), deaffricated to [?] (Old Spanish), devoiced to [?] (16th century), and finally retracted to a velar, giving [x] (c. 1650). (See History of the Spanish language and Phonological history of Spanish coronal fricatives for more information).
Palatalization has played a major role in the history of English, and of other languages and language groups throughout the world, such as the Romance, Greek, Slavic, Baltic, Finnic, Swedish, Norwegian, Mordvinic, Samoyedic, Iranian, Indo-Aryan, Goidelic, Korean, Japanese, Chinese, Albanian, Arabic, and Micronesian languages.
In Anglo-Frisian, the language that gave rise to English and the Frisian languages, the velar stops /k ?/ and the consonant cluster /sk/ were palatalized in certain cases and became the sounds /t?/, /d?/, /j/, and /?/. Many words with Anglo-Frisian palatalization survive in Modern English, and the palatalized sounds are typically spelled ⟨ch⟩, ⟨(d)ge⟩, ⟨y⟩, and ⟨sh⟩ in Modern English.
Palatalization only occurred in certain environments, and so it did not apply to all words from the same root. This is the origin of some alternations in cognate words, such as speak and speech /'spi:k, 'spi:t?/, cold and chill /'ko?ld, 'tl/, burrow and bury /'b?ro?, 'b?ri/, dawn and day /'d?:n, 'de?/. Here ⟨k⟩ originates from unpalatalized /k/ and ⟨w⟩ from unpalatalized /?/.
Some English words with palatalization have unpalatalized doublets from the Northumbrian dialect and from Old Norse, such as shirt and skirt /'rt, 'sk?rt/, church and kirk /'trt?, 'k?rk/, ditch and dike /'d?t?, 'da?k/. German only underwent palatalization of /sk/: cheese /t?i:z/ and Käse /k?:z?/; lie and lay /'la?, 'le?/, liegen and legen /'li:n, 'le:n/; fish and Fisch /f/.
The pronunciation of wicca as ['w?k?] with a hard ⟨c⟩ is a spelling pronunciation, since the actual Old English pronunciation gave rise to witch.

Others include the following:
In some English-speaking areas, the sound /s/ changed to /?/, like for example in the words Worcestershire (/w?s.t?.?i?/ to /w.t?.?i?/) and Association (/so?si'en/ to /soi'en/). Various other examples include Asphault, (to)assume.
While in most Semitic languages, e.g. Aramaic, Hebrew, Ge'ez the Gimel represents a [?], Arabic is considered unique among them where the Gimel or J?m ⟨?⟩ was palatalized to an affricate [d] or a fricative [?] in most dialects from classical times. While there is variation in Modern Arabic varieties, most of them reflect this palatalized pronunciation except in Egyptian Arabic and a number of Yemeni and Omani dialects, where it is pronounced as [?]. It is not well known when this change occurred or if it is connected to the pronunciation of Q?f ⟨?⟩ as a [?], but in most of the Arabian peninsula which is the homeland of the Arabic language, the ⟨?⟩ represents a [d] and ⟨?⟩ represents a [?], except in western and southern Yemen and parts of Oman where ⟨?⟩ represents a [?] and ⟨?⟩ represents a [q], which shows a strong correlation between the palatalization of ⟨?⟩ to [d] and the pronunciation of the ⟨?⟩ as a [?] as shown in the table below:
|Language / Dialects||Pronunciation of the letters|
|Parts of Southern Arabia||/?/||/q/|
|Most Arabian Peninsular Dialects||/d/||/?/|
|Modern Standard Arabic||/d/||/q/|
Some modern Arabic varieties developed palatalization of ⟨?⟩ (turning into , , , or ), ⟨?⟩ (turning [?~q] into or ) and ⟨?⟩ (turning into ), usually when adjacent to front vowel, though these palatalizations also occur in other environments as well. These three palatalizations occur in a variety of dialects, including Iraqi, rural Palestinian varieties, a number of Gulf Arabic dialects, such as Kuwaiti, Qatari, Bahraini, and Emarati, as well as others in the Arab peninsula like Najdi, the southern dialects of Saudi Arabia, and various Bedouin dialects. Examples:
Palatalization occurs in the pronunciation of the second person feminine singular pronoun in those dialects. For instance :
Classical Arabic ('your [f.] eye') /?ajnuki/ is pronounced:
speakers in these dialects that do not use the palatalization would merge the feminine and masculine suffix pronouns e.g. ? [?e?:n?k] ('your eye' to a male/female) as opposed to Classical Arabic /?ajnuka/ ('your eye' to a male) and /?ajnuki/ ('your eye' to a female) and most other modern urban dialects /?e:nak/ (to a male) and /?e:nik/ (to a female).
Assyrian Neo-Aramaic features the palatalization of kaph (turning /k/ into ), taw (turning /t/ into ) and gimel (turning /?/ into ), albeit in some dialects only and seldom in the standardized version of the language.
The Romance languages developed from Vulgar Latin, the colloquial form of Latin spoken in the Roman Empire. Various palatalizations occurred during the historical development of the Romance languages. Some groups of the Romance languages underwent more palatalizations than others. One palatalization affected all groups, some palatalizations affected most groups, and one affected only a few groups.
In Gallo-Romance, Vulgar Latin *[ka] became *[t?a] very early, with the subsequent deaffrication and some further developments of the vowel. For instance:
Early English borrowings from French show the original affricate, as chamber /'t?e?mb/ "(private) room" < Old French chambre /tmbr?/ < Vulgar Latin camera; compare French chambre /b?/ "room".
Mouillé (French pronunciation: [muje], "moistened") is a term for palatal consonants in the Romance languages. Palatal consonants in the Romance languages developed from or by palatalization.
|l mouillé||n mouillé|
L and n mouillé have a variety of origins in the Romance languages. In these tables, letters that represent or used to represent or are bolded. In French, /?/ merged with /j/ in pronunciation in the 18th century; in most dialects of Spanish, /?/ has merged with /?/ into the new phoneme of . Romanian formerly had both /?/ and /?/, but both have merged with /j/: v?nea > *vi?e > Romanian vie /'vi.je/ "vineyard"; mulierem > *mu?ere > Romanian muiere /mu'je.re/ "woman".
In certain Indo-European language groups, the reconstructed "palato-velars" of Proto-Indo-European (*?, *?, *) were palatalized into sibilants. The language groups with and without palatalization are called satem and centum languages, after the characteristic developments of the PIE word for "hundred":
In the Slavic languages, two palatalizations took place. Both affected the Proto-Slavic velars *k *g *x. In the first palatalization, the velars before the front vowels *e *? *i *? and the palatal approximant *j changed to *? *? *?. In the second palatalization, the velars changed to c, dz or z, and s or ? before the Proto-Slavic diphthongs *aj *?j, which must have been monophthongized to *? by this time.
In many dialects of Mandarin Chinese,[clarification needed] the alveolar sibilants /ts ts? s/ and the velars /k k? x/ were palatalized before the medials /j ?/ and merged in pronunciation, yielding the alveolo-palatal sibilants /t? t ?/. Alveolo-palatal consonants occur in modern Standard Chinese and are written as ⟨j q x⟩ in Pinyin. Postal romanization does not show palatalized consonants, reflecting the dialect of the imperial court during the Qing dynasty. For instance, the name of the capital of China was formerly spelled Peking, but is now spelled Be?j?ng , and Tientsin and Sian were the former spellings of Ti?nj?n and X?'?n [?í.án].
