Sound changeA 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 (or, more generally, one phonetic feature value) by a different one (called phonetic change) or a more general change to the speech sounds that exist (phonological change), 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.
DialectDialect (from Latin dialectus, dialectos, from the Ancient Greek word διάλεκτος, 'discourse', from διά, 'through' and λέγω, 'I speak') can refer to two distinctly different types of linguistic phenomena. One usage refers to a variety of a language that is a characteristic of a particular group of the language's speakers. Under this definition, the dialects or varieties of a particular language are closely related and, despite their differences, are most often largely mutually intelligible, especially if geographically close to one another in a dialect continuum.
Dutch languageDutch (Nederlands ˈneːdərlɑnts), also known as Netherlandic or Netherlandish, is a West Germanic language spoken by about 25 million people as a first language and 5 million as a second language. It is the third most widely spoken Germanic language, after its close relatives German and English. Afrikaans is a separate but somewhat mutually intelligible daughter language spoken, to some degree, by at least 16 million people, mainly in South Africa and Namibia, evolving from the Cape Dutch dialects of Southern Africa.
Italian languageItalian (italiano itaˈljaːno or lingua italiana ˈliŋɡwa itaˈljaːna) is a Romance language of the Indo-European language family that evolved from the Vulgar Latin of the Roman Empire. Together with Sardinian, Italian is the least divergent language from Latin. Spoken by about 85 million people (2022), Italian is an official language in Italy, San Marino, Switzerland (Ticino and the Grisons), and is the primary language of Vatican City. It has official minority status in Croatia and in some areas of Slovenian Istria.
Vowel reductionIn phonetics, vowel reduction is any of various changes in the acoustic quality of vowels as a result of changes in stress, sonority, duration, loudness, articulation, or position in the word (e.g. for the Creek language), and which are perceived as "weakening". It most often makes the vowels shorter as well. Vowels which have undergone vowel reduction may be called reduced or weak. In contrast, an unreduced vowel may be described as full or strong. There are several ways to distinguish full and reduced vowels in transcription.
