In phonology, an allophone is one of multiple possible spoken sounds – or phones – or signs used to pronounce a single phoneme in a particular language. For example, in English, the voiceless plosive (as in stop
In articulatory phonetics, a consonant is a speech sound that is articulated with complete or partial closure of the vocal tract. Examples are and [b], pronounced with the lips; and [d], pronounced with the front of the tongue; and [g], pronounced with the back of the tongue;, pronounced in the throat;, [v], and, pronounced by forcing air through a narrow channel (fricatives); and and, which have air flowing through the nose (nasals). Contrasting with consonants are vowels.
In phonetics, a nasal, also called a nasal occlusive or nasal stop in contrast with an oral stop or nasalized consonant, is an occlusive consonant produced with a lowered velum, allowing air to escape freely through the nose. The vast majority of consonants are oral consonants. Examples of nasals in English are, and, in words such as nose, bring and mouth. Nasal occlusives are nearly universal in human languages. There are also other kinds of nasal consonants in some languages.
A sound change, in historical linguistics, is a change in the pronunciation of a language. A sound change can involve the replacement of one speech sound by a different one or a more general change to the speech sounds that exist, such as the merger of two sounds or the creation of a new sound. A sound change can eliminate the affected sound, or a new sound can be added. Sound changes can be environmentally conditioned if the change occurs in only some sound environments, and not others.
A vowel is a syllabic speech sound pronounced without any stricture in the vocal tract. Vowels are one of the two principal classes of speech sounds, the other being the consonant. Vowels vary in quality, in loudness and also in quantity (length). They are usually voiced and are closely involved in prosodic variation such as tone, intonation and stress.
A syllable is a unit of organization for a sequence of speech sounds typically made up of a syllable nucleus with optional initial and final margins. Syllables are often considered the phonological "building blocks" of words. They can influence the rhythm of a language, its prosody, its poetic metre and its stress patterns. Speech can usually be divided up into a whole number of syllables: for example, the word ignite is made of two syllables: ig and nite.
Assimilation is a sound change in which some phonemes change to become more similar to other nearby sounds. A common type of phonological process across languages, assimilation can occur either within a word or between words.
A nasal vowel is a vowel that is produced with a lowering of the soft palate so that the air flow escapes through the nose and the mouth simultaneously, as in the French vowel /ɑ̃/ or Amoy []. By contrast, oral vowels are produced without nasalization.
The phonology of Portuguese varies among dialects, in extreme cases leading to some difficulties in intelligibility. Portuguese is a pluricentric language and has some of the most diverse sound variations in any language. This article on phonology focuses on the pronunciations that are generally regarded as standard. Since Portuguese is a pluricentric language—and differences between European Portuguese (EP), Brazilian Portuguese (BP), and Angolan Portuguese (AP) can be considerable—varieties are distinguished whenever necessary.
In phonology, epenthesis means the addition of one or more sounds to a word, especially in the beginning syllable (prothesis) or in the ending syllable (paragoge) or in-between two syllabic sounds in a word. The word epenthesis comes from epi- "in addition to" and en- "in" and thesis "putting". Epenthesis may be divided into two types: excrescence for the addition of a consonant, and for the addition of a vowel, svarabhakti or alternatively anaptyxis. The opposite process, where one or more sounds are removed, is referred to as elision.
In linguistics, prothesis, or less commonly prosthesis is the addition of a sound or syllable at the beginning of a word without changing the word's meaning or the rest of its structure. A vowel or consonant added by prothesis is called prothetic or less commonly prosthetic.
In historical linguistics, vowel breaking, vowel fracture, or diphthongization is the sound change of a monophthong into a diphthong or triphthong.
In linguistics, a distinctive feature is the most basic unit of phonological structure that distinguishes one sound from another within a language. For example, the feature [voice] distinguishes the two bilabial plosives: [p] and [b]. There are many different ways of defining and arranging features into feature systems: some deal with only one language while others are developed to apply to all languages.
A syllabic consonant or vocalic consonant is a consonant that forms a syllable on its own, like the m, n and l in some pronunciations of the English words rhythm, button and bottle. To represent it, the understroke diacritic in the International Phonetic Alphabet is used, ⟨U+0329◌̩COMBINING VERTICAL LINE BELOW⟩. It may be instead represented by an overstroke, ⟨U+030D◌̍COMBINING VERTICAL LINE ABOVE⟩ if the symbol that it modifies has a descender, such as in.
Ikwerre, sometimes spelt as Ikwere, is a type of Igboid language spoken primarily by the Ikwerre people, who inhabit certain areas of Rivers State, Nigeria. It is the biggest Igboid variety along with Ngwa of Abia State.
The phonology of Sesotho and those of the other Sotho–Tswana languages are radically different from those of "older" or more "stereotypical" Bantu languages. Modern Sesotho in particular has very mixed origins inheriting many words and idioms from non-Sotho–Tswana languages.
Taos is a Tanoan language spoken by several hundred people in New Mexico, in the United States. The main description of its phonology was contributed by George L. Trager in a (pre-generative) structuralist framework. Earlier considerations of the phonetics-phonology were by John P. Harrington and Jaime de Angulo. Trager's first account was in Trager (1946) based on fieldwork 1935-1937, which was then substantially revised in Trager (1948). The description below takes Trager (1946) as the main point of departure and notes where this differs from the analysis of Trager (1948). Harrington's description is more similar to Trager (1946). Certain comments from a generative perspective are noted in a comparative work Hale (1967).
In phonetics and historical linguistics, fusion, or coalescence, is a sound change where two or more segments with distinctive features merge into a single segment. This can occur both on consonants and in vowels. A word like educate is one that may exhibit fusion, e.g. or. A merger between two segments can also occur between word boundaries, an example being the phrase got ya being pronounced like gotcha. Most cases of fusion lead to allophonic variation, though some sequences of segments may lead to wholly distinct phonemes.
Izi is an Igboid language spoken in Ebonyi state in Nigeria. It forms a dialect cluster with the closely related languages Ikwo, Ezza, and Mgbo.
Kensiu (Kensiw) is an Austro-asiatic language of the Jahaic subbranch. It is spoken by a small community of 300 in Yala Province in southern Thailand and also reportedly by a community of approximately 300 speakers in Western Malaysia in Perak and Kedah States. Speakers of this language are Negritos who are known as the Mani people or Maniq of Thailand.
