Regional dialect in the context of "Language family"

Sociolinguistics is the descriptive, scientific study of how language is shaped by, and used differently within, any given society. The field largely looks at how a language varies between distinct social groups and under the influence of assorted cultural norms, expectations, and contexts, including how that variation plays a role in language change. Sociolinguistics combines the older field of dialectology with the social sciences in order to identify regional dialects, sociolects, ethnolects, and other sub-varieties and styles within a language.

A major branch of linguistics since the second half of the 20th century, sociolinguistics is closely related to and can partly overlap with pragmatics, linguistic anthropology, and sociology of language, the latter focusing on the effect of language back on society. Sociolinguistics' historical interrelation with anthropology can be observed in studies of how language varieties differ between groups separated by social variables (e.g., ethnicity, religion, status, gender, level of education, age, etc.) or geographical barriers (a mountain range, a desert, a river, etc.). Such studies also examine how such differences in usage and in beliefs about usage produce and reflect social or socioeconomic classes. As the usage of a language varies from place to place, language usage also varies among social classes, and some sociolinguists study these sociolects.

Māori (Māori: [ˈmaːɔɾi] ; endonym: te reo Māori [tɛ ɾɛɔ ˈmaːɔɾi], 'the Māori language', also shortened to te reo) is an Eastern Polynesian language and the language of the Māori people, the indigenous population of mainland New Zealand. The southernmost member of the Austronesian language family, it is related to Cook Islands Māori, Tuamotuan, and Tahitian. The Māori Language Act 1987 gave the language recognition as one of New Zealand's official languages. There are regional dialects of the Māori language.Prior to contact with Europeans, Māori lacked a written language or script. Written Māori now uses the Latin script, which was adopted and the spelling standardised by Northern Māori in collaboration with English Protestant clergy in the 19th century.

In the second half of the 19th century, European children in rural areas spoke Māori with Māori children. It was common for prominent parents of these children, such as government officials, to use Māori in the community. Māori declined due to the increase of the European population and government-imposed educational policies; by the early 20th century its use was banned in school playgrounds and classrooms across the country. The number of speakers fell sharply after 1945, but a Māori language revival movement began in the late 20th century and slowed the decline. The Māori protest movement and the Māori renaissance of the 1970s caused greater social awareness of and support for the language.

Southern American English or Southern U.S. English is a regional dialect or collection of dialects of American English spoken throughout the Southern United States, primarily by White Southerners and increasingly concentrated in more rural areas. As of 2000s research, its most innovative accents include southern Appalachian and certain Texas accents. Such research has described Southern American English as the largest American regional accent group by number of speakers. More formal terms used within American linguistics include Southern White Vernacular English and Rural White Southern English. However, more commonly in the United States, the variety is recognized as a Southern accent, which technically refers merely to the dialect's sound system, often also called a Southern twang, or simply Southern.
