Consonant clusterIn 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 /spl/ and /ts/ 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.
Consonant mutationConsonant mutation is change in a consonant in a word according to its morphological or syntactic environment. Mutation occurs in languages around the world. A prototypical example of consonant mutation is the initial consonant mutation of all modern Celtic languages. Initial consonant mutation is also found in Indonesian or Malay, in Nivkh, in Southern Paiute and in several West African languages such as Fula. The Nilotic language Dholuo, spoken in Kenya, shows mutation of stem-final consonants, as does English to a small extent.
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.
Gothic languageGothic is an extinct East Germanic language that was spoken by the Goths. It is known primarily from the Codex Argenteus, a 6th-century copy of a 4th-century Bible translation, and is the only East Germanic language with a sizeable text corpus. All others, including Burgundian and Vandalic, are known, if at all, only from proper names that survived in historical accounts, and from loanwords in other languages such as Portuguese, Spanish, Catalan, Occitan and French. As a Germanic language, Gothic is a part of the Indo-European language family.
Irish languageIrish (Standard Irish: Gaeilge), also known as Gaelic 'geilIk, is a Goidelic language of the Insular Celtic branch of the Celtic language family, which is a part of the Indo-European language family. Irish is indigenous to the island of Ireland and was the population's first language until the 19th century, when English gradually became dominant, particularly in the last decades of the century. Today, Irish is still commonly spoken as a first language in areas of Ireland collectively known as the Gaeltacht, in which only 2% of Ireland's population lived in 2016.
Vowel harmonyIn phonology, vowel harmony is an 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.
PronunciationPronunciation is the way in which a word or a language is spoken. This may refer to generally agreed-upon sequences of sounds used in speaking a given word or language in a specific dialect ("correct" or "standard" pronunciation) or simply the way a particular individual speaks a word or language. Words' pronunciations can be found in reference works such as dictionaries. General-purpose dictionaries typically only include standard pronunciations, but regional or dialectal pronunciations may be found in more specific works.
Brazilian PortugueseBrazilian Portuguese (português brasileiro poʁtʊˈɡe(j)z bɾazɪˈlejɾʊ ), also Portuguese of Brazil (português do Brasil, poʁtʊˈɡe(j)z dʊ bɾɐˈziw ) or South American Portuguese (português sul-americano) is the set of varieties of the Portuguese language native to Brazil and the most influential form of Portuguese worldwide. It is spoken by almost all of the 203 million inhabitants of Brazil and spoken widely across the Brazilian diaspora, today consisting of about two million Brazilians who have emigrated to other countries.
Rhoticity in EnglishRhoticity in English is the pronunciation of the historical rhotic consonant /r/ by English speakers. The presence or absence of rhoticity is one of the most prominent distinctions by which varieties of English can be classified. In rhotic varieties, the historical English /r/ sound is preserved in all pronunciation contexts. In non-rhotic varieties, speakers no longer pronounce /r/ in postvocalic environments: when it is immediately after a vowel and not followed by another vowel.
PhonotacticsPhonotactics (from Ancient Greek phōnḗ "voice, sound" and taktikós "having to do with arranging") is a branch of phonology that deals with restrictions in a language on the permissible combinations of phonemes. Phonotactics defines permissible syllable structure, consonant clusters and vowel sequences by means of phonotactic constraints. Phonotactic constraints are highly language-specific. For example, in Japanese, consonant clusters like /st/ do not occur.
