Phonological changeIn historical linguistics, phonological change is any sound change that alters the distribution of phonemes in a language. In other words, a language develops a new system of oppositions among its phonemes. Old contrasts may disappear, new ones may emerge, or they may simply be rearranged. Sound change may be an impetus for changes in the phonological structures of a language (and likewise, phonological change may sway the process of sound change).
Vowel hiatusIn phonology, hiatus, diaeresis (daɪˈɛrəsəs,_-ˈɪər-), or dieresis describes the occurrence of two separate vowel sounds in adjacent syllables with no intervening consonant. When two vowel sounds instead occur together as part of a single syllable, the result is called a diphthong. Some languages do not have diphthongs, except sometimes in rapid speech, or they have a limited number of diphthongs but also numerous vowel sequences that cannot form diphthongs and so appear in hiatus.
MonophthongA monophthong (ˈmɒnəfθɒŋ,_ˈmɒnəp- ; , ) is a pure vowel sound, one whose articulation at both beginning and end is relatively fixed, and which does not glide up or down towards a new position of articulation. The monophthongs can be contrasted with diphthongs, where the vowel quality changes within the same syllable, and hiatus, where two vowels are next to each other in different syllables. A vowel sound whose quality does not change over the duration of the vowel is called a pure vowel.
French phonologyFrench phonology is the sound system of French. This article discusses mainly the phonology of all the varieties of Standard French. Notable phonological features include its uvular r, nasal vowels, and three processes affecting word-final sounds: liaison, a specific instance of sandhi in which word-final consonants are not pronounced unless they are followed by a word beginning with a vowel; elision, in which certain instances of ə (schwa) are elided (such as when final before an initial vowel); enchaînement (resyllabification) in which word-final and word-initial consonants may be moved across a syllable boundary, with syllables crossing word boundaries: An example of the above is this: Written: On a laissé la fenêtre ouverte.
Canadian raisingCanadian raising (also sometimes known as English diphthong raising) is an allophonic rule of phonology in many varieties of North American English that changes the pronunciation of diphthongs with open-vowel starting points. Most commonly, the shift affects aɪ or aʊ, or both, when they are pronounced before voiceless consonants (therefore, in words like price and clout, respectively, but not in prize and cloud). In North American English, /aɪ/ and /aʊ/ usually begin in an open vowel [ä~a], but through raising they shift to ɐ, ʌ or ə.
DiaphonemeA diaphoneme is an abstract phonological unit that identifies a correspondence between related sounds of two or more varieties of a language or language cluster. For example, some English varieties contrast the vowel of late (/eː/) with that of wait or eight (/ɛɪ/). Other English varieties contrast the vowel of late or wait (/eː/) with that of eight (/ɛɪ/). This non-overlapping pair of phonemes from two different varieties can be reconciled by positing three different diaphonemes: A first diaphoneme for words like late (⫽e⫽), a second diaphoneme for words like wait (⫽ei⫽), and a third diaphoneme for words like eight (⫽ex⫽).
L-vocalizationL-vocalization, in linguistics, is a process by which a lateral approximant sound such as l, or, perhaps more often, velarized ɫ, is replaced by a vowel or a semivowel. There are two types of l-vocalization: A labiovelar approximant, velar approximant, or back vowel: [ɫ] > [w] or [ɰ] > [u] or [ɯ] A front vowel or palatal approximant: [l] > [j] > [i] Examples of L-vocalization can be found in many West Germanic languages, including English, Scots, Dutch, and some German dialects.
Stress in SpanishStress in Spanish is functional: to change the placement of stress changes the meaning of a sentence or phrase: for example, célebre ('famous'), celebre ('[that] he/she celebrates'), and celebré ('I celebrated') contrast only by stress. There is some minor variance between Spanish dialects; a speaker of Rioplatense Spanish will pronounce boina ('beret') as ˈbojna while a speaker of Colombian Spanish will pronounce it as boˈina. Spanish has only two degrees of stress.
Isan languageIsan or Northeastern Thai (ภาษาอีสาน, ภาษาไทยถิ่นตะวันออกเฉียงเหนือ, ภาษาไทยถิ่นอีสาน, ภาษาไทยอีสาน, ภาษาลาวตะวันตก, ภาษาลาวอีสาน) refers to the local development of the Lao language in Thailand, after the political split of the Lao-speaking world at the Mekong River, with the eastern bank eventually becoming modern Laos and the western bank the Isan region of Thailand (formerly known as Siam prior to 1932), after the conclusion of the Franco-Siamese War of 1893. The language is still referred to as Lao by native speakers.
