DiasystemIn the field of dialectology, a diasystem or polylectal grammar is a linguistic analysis set up to encode or represent a range of related varieties in a way that displays their structural differences. The term diasystem was coined by linguist and dialectologist Uriel Weinreich in a 1954 paper as part of an initiative in exploring how to extend advances in structuralist linguistic theory to dialectology to explain linguistic variation across dialects. Weinreich's paper inspired research in the late 1950s to test the proposal.
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.
Variation (linguistics)Variation is a characteristic of language: there is more than one way of saying the same thing. Speakers may vary in pronunciation (accent), word choice (lexicon), or morphology and syntax (sometimes called "grammar"). But while the diversity of variation is great, there seem to be boundaries on variation – speakers do not generally make drastic alterations in word order or use novel sounds that are completely foreign to the language being spoken.
SociolectIn sociolinguistics, a sociolect is a form of language (non-standard dialect, restricted register) or a set of lexical items used by a socioeconomic class, profession, an age group, or other social group. Sociolects involve both passive acquisition of particular communicative practices through association with a local community, as well as active learning and choice among speech or writing forms to demonstrate identification with particular groups.
IsoglossAn isogloss, also called a heterogloss (see Etymology below), is the geographic boundary of a certain linguistic feature, such as the pronunciation of a vowel, the meaning of a word, or the use of some morphological or syntactic feature. Major dialects are typically demarcated by bundles of isoglosses, such as the Benrath line that distinguishes High German from the other West Germanic languages and the La Spezia–Rimini Line that divides the Northern Italian languages and Romance languages west of Italy from Central Italian dialects and Romance languages east of Italy.
EtymologyEtymology (ˌɛtɪˈmɒlədʒi ) is the scientific study of the origin and evolution of a word's semantic meaning across time, including its constituent morphemes and phonemes. It is a subfield of historical linguistics, philology and semiotics, and draws upon comparative semantics, morphology, pragmatics, and phonetics in order to construct a comprehensive and chronological catalogue of all meanings that a morpheme, phoneme, word, or sign has carried across time.
Variety (linguistics)In sociolinguistics, a variety, also called an isolect or lect, is a specific form of a language or language cluster. This may include languages, dialects, registers, styles, or other forms of language, as well as a standard variety. The use of the word "variety" to refer to the different forms avoids the use of the term language, which many people associate only with the standard language, and the term dialect, which is often associated with non-standard varieties thought of as less prestigious or "correct" than the standard.
Pluricentric languageA pluricentric language or polycentric language is a language with several interacting codified standard forms, often corresponding to different countries. Many examples of such languages can be found worldwide among the most-spoken languages, including but not limited to Chinese in mainland China, Taiwan and Singapore; English in the United Kingdom, the United States, India, and elsewhere; and French in France, Canada, and elsewhere. The converse case is a monocentric language, which has only one formally standardized version.
Galician languageGalician (ɡəˈlɪʃən, ɡəˈlɪsiən; galego), also known as Galego, is a Western Ibero-Romance language. Around 2.4 million people have at least some degree of competence in the language, mainly in Galicia, an autonomous community located in northwestern Spain, where it has official status along with Spanish. The language is also spoken in some border zones of the neighbouring Spanish regions of Asturias and Castile and León, as well as by Galician migrant communities in the rest of Spain, in Latin America including Puerto Rico, the United States, Switzerland and elsewhere in Europe.
Mutual intelligibilityIn linguistics, mutual intelligibility is a relationship between languages or dialects in which speakers of different but related varieties can readily understand each other without prior familiarity or special effort. It is sometimes used as an important criterion for distinguishing languages from dialects, although sociolinguistic factors are often also used. Intelligibility between languages can be asymmetric, with speakers of one understanding more of the other than speakers of the other understanding the first.
