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.
Agreement (linguistics)In linguistics, agreement or concord (abbreviated ) occurs when a word changes form depending on the other words to which it relates. It is an instance of inflection, and usually involves making the value of some (such as gender or person) "agree" between varied words or parts of the sentence. For example, in Standard English, one may say I am or he is, but not "I is" or "he am". This is because English grammar requires that the verb and its subject agree in person.
Sign languageSign languages (also known as signed languages) are languages that use the visual-manual modality to convey meaning, instead of spoken words. Sign languages are expressed through manual articulation in combination with non-manual markers. Sign languages are full-fledged natural languages with their own grammar and lexicon. Sign languages are not universal and are usually not mutually intelligible, although there are also similarities among different sign languages.
Koiné languageIn linguistics, a koiné language, koiné dialect, or simply koiné (Ancient Greek κοινή, "common [language]") is a standard or common language or dialect that has arisen as a result of the contact, mixing, and often simplification of two or more mutually intelligible varieties of the same language. As speakers already understood one another before the advent of the koiné, the process of koineization is not as drastic as pidginization and creolization.
Natural languageIn neuropsychology, linguistics, and philosophy of language, a natural language or ordinary language is any language that occurs naturally in a human community by a process of use, repetition, and change without conscious planning or premeditation. It can take different forms, namely either a spoken language or a sign language. Natural languages are distinguished from constructed and formal languages such as those used to program computers or to study logic. Natural language can be broadly defined as different from artificial and constructed languages, e.
Copula (linguistics)In linguistics, a copula (plural: copulas or copulae; abbreviated ) is a word or phrase that links the subject of a sentence to a subject complement, such as the word is in the sentence "The sky is blue" or the phrase was not being in the sentence "It was not being co-operative." The word copula derives from the Latin noun for a "link" or "tie" that connects two different things. A copula is often a verb or a verb-like word, though this is not universally the case. A verb that is a copula is sometimes called a copulative or copular verb.
Post-creole continuumA post-creole continuum (or simply creole continuum) is a dialect continuum of varieties of a creole language between those most and least similar to the superstrate language (that is, a closely related language whose speakers assert or asserted dominance of some sort). Due to social, political, and economic factors, a creole language can decreolize towards one of the languages from which it is descended, aligning its morphology, phonology, and syntax to the local standard of the dominant language but to different degrees depending on a speaker's status.
Tok PisinTok Pisin (tɒk_ˈpɪsɪn, tɔːk,_-zɪn; Tok Pisin ˌtok piˈsin), often referred to by English speakers as New Guinea Pidgin or simply Pidgin, is a creole language spoken throughout Papua New Guinea. It is an official language of Papua New Guinea and the most widely used language in the country. However, in parts of the southern provinces of Western, Gulf, Central, Oro, and Milne Bay, the use of Tok Pisin has a shorter history and is less universal, especially among older people.
Krio languageThe Sierra Leonean Creole or Krio is an English-based creole language that is lingua franca and de facto national language spoken throughout the West African nation of Sierra Leone. Krio is spoken by 96 percent of the country's population, and it unites the different ethnic groups in the country, especially in their trade and social interaction with each other. Krio is the primary language of communication among Sierra Leoneans at home and abroad, and has also heavily influenced Sierra Leonean English.
DecreolizationDecreolization is a postulated phenomenon whereby over time a creole language reconverges with the lexifier from which it originally derived. The notion has attracted criticism from linguists who argue there is little theoretical or empirical basis on which to postulate a process of language change which is particular to creole languages. Decreolization is a process of language change a creole language may undergo when in contact with its lexifier.
