Vowel reduction in the context of "English phonology"

Uyghur, formerly known as Turki or Eastern Turki, is a Turkic language of the Karluk branch, with 8 to 13 million native speakers (as of 2021). It is spoken primarily by the Uyghur people, most of whom live in what is now the Xinjiang Uyghur Autonomous Region of Western China. Apart from Xinjiang, significant communities of Uyghur speakers are also located in Kazakhstan, Kyrgyzstan, and Uzbekistan, and various other countries. Uyghur is a lingua franca of Xinjiang; it is widely used in both social and official spheres, as well as in print, television, and radio. Other ethnic minorities in Xinjiang also use Uyghur as a common language.

Uyghur belongs to the Karluk branch of the Turkic language family, which includes languages such as Uzbek. Like many other Turkic languages, Uyghur displays vowel harmony and agglutination, lacks noun classes or grammatical gender, and is a left-branching language with subject–object–verb word order. More distinctly, Uyghur processes include vowel reduction and umlauting, especially in northern dialects. In addition to other Turkic languages, Uyghur has historically been strongly influenced by Arabic and Persian, and more recently by Russian and Mandarin Chinese.

Götamål is one of the six dialect areas of the Swedish language, mostly heard in Västergötland, Dalsland, northern Halland, northern Småland and Östergötland. However, it is also heard in Bohuslän and Värmland. Examples of Götamål features are vowel reduction, vowel shortening in front of endings and loss of /r/ in suffixes, such as in hästa instead of hästar, eng. horses.

Crasis (/ˈkreɪsɪs/; from the Greek κρᾶσις, lit. 'mixing' or 'blending') is a type of contraction in which two vowels or diphthongs merge into one new vowel or diphthong, making one word out of two (univerbation). Crasis occurs in many languages, including French, Italian, Portuguese, and Spanish; it was first described in Ancient Greek.

In some cases, as in the French examples, crasis involves the grammaticalization of two individual lexical items into one. However, in other cases, like in the Greek examples, crasis is the orthographic representation of the encliticization and the vowel reduction of one grammatical form with another. The difference between them is that the Greek examples involve two grammatical words and a single phonological word, but the French examples involve a single phonological word and grammatical word.

Like many other languages, English has wide variation in pronunciation, both historically and from dialect to dialect. In general, however, the regional dialects of English share a largely similar (but not identical) phonological system. Among other things, most dialects have vowel reduction in unstressed syllables and a complex set of phonological features that distinguish fortis and lenis consonants (stops, affricates, and fricatives).

This article describes the development of the phonology of English over time, starting from its roots in proto-Germanic to diverse changes in different dialects of modern English.
