Defaka Language
Defaka is an endangered and divergent Nigerian language of uncertain classification. It is spoken in the Opobo–Nkoro LGA of Rivers State, in the Defaka or Afakani ward of Nkọrọ town and Ịwọma Nkọrọ. The low number of Defaka speakers, coupled with the fact that other languages dominate the region where Defaka is spoken, edges the language near extinction on a year-to-year basis. It is generally classified in an Ijoid branch of the Niger–Congo family. However, the Ijoid proposal is problematic. Blench (2012) notes that "Defaka has numerous external cognates and might be an isolate or independent branch of Niger–Congo which has come under Ịjọ influence."Roger BlenchNiger-Congo: an alternative view/ref> People Ethnically, the Defaka people are distinct from the Nkoroo, but they have assimilated to Nkoroo culture to such a degree that their language seems to be the only sign of a distinct Defaka identity. Use of the Defaka language however is quickly receding in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nigeria
Nigeria ( ), , ig, Naìjíríyà, yo, Nàìjíríà, pcm, Naijá , ff, Naajeeriya, kcg, Naijeriya officially the Federal Republic of Nigeria, is a country in West Africa. It is situated between the Sahel to the north and the Gulf of Guinea to the south in the Atlantic Ocean. It covers an area of , and with a population of over 225 million, it is the most populous country in Africa, and the world's sixth-most populous country. Nigeria borders Niger in the north, Chad in the northeast, Cameroon in the east, and Benin in the west. Nigeria is a federal republic comprising of 36 states and the Federal Capital Territory, where the capital, Abuja, is located. The largest city in Nigeria is Lagos, one of the largest metropolitan areas in the world and the second-largest in Africa. Nigeria has been home to several indigenous pre-colonial states and kingdoms since the second millennium BC, with the Nok civilization in the 15th century BC, marking the first ...

Lenition
In linguistics, lenition is a sound change that alters consonants, making them more sonority hierarchy, sonorous. The word ''lenition'' itself means "softening" or "weakening" (from Latin 'weak'). Lenition can happen both synchronic analysis, synchronically (within a language at a particular point in time) and historical linguistics, diachronically (as a evolutionary linguistics, language changes over time). Lenition can involve such changes as Voice (phonetics), voicing a voiceless consonant, causing a consonant to relax Occlusive, occlusion, to lose its place of articulation (a phenomenon called ''debuccalization'', which turns a consonant into a glottal consonant like or ), or even causing a consonant to disappear entirely. An example of synchronic lenition is found in most varieties of American English, in the form of flapping: the of a word like ''wait'' is pronounced as the more sonorous in the related form ''waiting'' . Some varieties of Spanish language, Spanish show ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Consonant Cluster
In linguistics, a consonant cluster, consonant sequence or consonant compound, is a group of consonants which have no intervening vowel. In English, for example, the groups and are consonant clusters in the word ''splits''. In the education field it is variously called a consonant cluster or a consonant blend. Some linguists argue that the term can be properly applied only to those consonant clusters that occur within one syllable. Others claim that the concept is more useful when it includes consonant sequences across syllable boundaries. According to the former definition, the longest consonant clusters in the word ''extra'' would be and , whereas the latter allows , which is phonetically in some accents. Phonotactics Each language has an associated set of phonotactic constraints. Languages' phonotactics differ as to what consonant clusters they permit. Many languages are more restrictive than English in terms of consonant clusters, and some forbid consonant clusters ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Voice Onset Time
In phonetics, voice onset time (VOT) is a feature of the production of stop consonants. It is defined as the length of time that passes between the release of a stop consonant and the onset of voicing, the vibration of the vocal folds, or, according to other authors, periodicity. Some authors allow negative values to mark voicing that begins during the period of articulatory closure for the consonant and continues in the release, for those unaspirated voiced stops in which there is no voicing present at the instant of articulatory closure. History The concept of voice onset time can be traced back as far as the 19th century, when Adjarian (1899: 119) [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tenuis Consonant
In linguistics, a tenuis consonant ( or ) is an obstruent that is voiceless, unaspirated and unglottalized. In other words, it has the "plain" phonation of with a voice onset time close to zero (a zero-VOT consonant), as Spanish ''p, t, ch, k'' or English ''p, t, k'' after ''s'' (''spy, sty, sky''). For most languages, the distinction is relevant only for stops and affricates. However, a few languages have analogous series for fricatives. Mazahua, for example, has ejective, aspirated, and voiced fricatives alongside tenuis , parallel to stops alongside tenuis . Many click languages have tenuis click consonants alongside voiced, aspirated, and glottalized series. Transcription In transcription, tenuis consonants are not normally marked explicitly, and consonants written with voiceless IPA letters, such as , are typically assumed to be unaspirated and unglottalized unless otherwise indicated. However, aspiration is often left untranscribed if no contrast needs to be made ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Obstruent
An obstruent () is a speech sound such as , , or that is formed by ''obstructing'' airflow. Obstruents contrast with sonorants, which have no such obstruction and so resonate. All obstruents are consonants, but sonorants include vowels as well as consonants. Subclasses Obstruents are subdivided into plosives (oral stops), such as , with complete occlusion of the vocal tract, often followed by a release burst; fricatives, such as , with limited closure, not stopping airflow but making it turbulent; and affricates, which begin with complete occlusion but then release into a fricative-like release, such as .Zsiga, Elizabeth. ''The Sounds of Language: An Introduction to Phonetics and Phonology''. Wiley-Blackwell, 2013. Voicing Obstruents are often prototypically voiceless, but voiced obstruents are common. This contrasts with sonorants, which are prototypically voiced and only rarely voiceless. See also *List of phonetics topics A * Acoustic phonetics * Active articulato ...

Vowel Harmony
In phonology, vowel harmony is an Assimilation (linguistics), assimilatory process in which the vowels of a given domain – typically a phonological word – have to be members of the same natural class (thus "in harmony"). Vowel harmony is typically long distance, meaning that the affected vowels do not need to be immediately adjacent, and there can be intervening segments between the affected vowels. Generally one vowel will trigger a shift in other vowels, either progressively or regressively, within the domain, such that the affected vowels match the relevant feature of the trigger vowel. Common phonological features that define the natural classes of vowels involved in vowel harmony include vowel backness, vowel height, nasalization, roundedness, and advanced and retracted tongue root. Vowel harmony is found in many Agglutination, agglutinative languages. The given domain of vowel harmony taking effect often spans across morpheme boundaries, and suffixes and prefixes will ...

Word Tone
Tone is the use of pitch in language to distinguish lexical or grammatical meaning – that is, to distinguish or to inflect words. All verbal languages use pitch to express emotional and other paralinguistic information and to convey emphasis, contrast and other such features in what is called intonation, but not all languages use tones to distinguish words or their inflections, analogously to consonants and vowels. Languages that have this feature are called tonal languages; the distinctive tone patterns of such a language are sometimes called tonemes, by analogy with ''phoneme''. Tonal languages are common in East and Southeast Asia, Africa, the Americas and the Pacific. Tonal languages are different from pitch-accent languages in that tonal languages can have each syllable with an independent tone whilst pitch-accent languages may have one syllable in a word or morpheme that is more prominent than the others. Mechanics Most languages use pitch as intonation to conve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Downstep
Downstep is a phenomenon in tone languages in which if two syllables have the same tone (for example, both with a high tone or both with a low tone), the second syllable is lower in pitch than the first. Two main kinds of downstep can be distinguished. The first, more usually called automatic downstep, downdrift or catathesis, occurs when high and low tones come in the sequence H L (L) H; the second high tone tends to be lower than the first because of the intervening low toned syllable. That phenomenon is common in African languages, such as Chichewa. It has also been argued that the same phenomenon is heard in English sentences, if these sentences are pronounced with a falling intonation, for example ''I really believe Ebenezer was a dealer in magnesium'', or ''I bought blueberries, bayberries, raspberries, mulberries, and brambleberries''. Downstep proper, or non-automatic downstep, is another phenomenon found in many African languages such as Igbo. for an overview of downst ...

Contour Tone
A tone contour, or contour tone, is a tone in a tonal language which shifts from one pitch to another over the course of the syllable or word. Tone contours are especially common in East, Southeast Asia, West Africa, Nilo-Saharan languages, Khoisan languages, Oto-Manguean languages and some languages of South America. Contours When the pitch descends, the contour is called a ''falling tone;'' when it ascends, a ''rising tone;'' when it descends and then returns, a ''dipping'' or ''falling-rising tone;'' and when it ascends and then returns, it is called a ''peaking'' or ''rising-falling tone.'' A tone in a contour-tone language which remains at approximately an even pitch is called a ''level tone.'' Tones which are too short to exhibit much of a contour, typically because of a final plosive consonant, may be called '' checked, abrupt, clipped,'' or ''stopped tones.'' It has been theorized that the relative timing of a contour tone is not distinctive. That is, in some accents or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
