1. Sociolinguistics
Standard language: idealised, official language for education and broadcasting.
Dialect: varieties of a language that have noticeable differences of grammar, vocabulary, and pronunciation which signal geographical, educational, ethnic, socio-economic background of speakers. These do not hinder communication between speakers of dialects.
Accent: Pronunciation differences between two speakers.

Ethnic dialects: Black, Chicano, German, Hawaiian, and Puerto Rican English
Continental Variation: Pronunciation, vocabulary, inflections-British, American, Canadian, Australian, and New Zealand)
Dialectology: Speakers of two different dialects of the same language can usually understand each other. Standard dialects of the languages are more prestigious.

3. Sociolinguistics
İsogloss: a line or map separating two areas in which a particular linguistic feature is significantly different.
Dialect boundary: a line representing a set of isoglosses, used to separate one dialect area from another.
Dialect continuum: the gradual merging of one regional variety of a language into another.

4. Sociolinguistics

Historical Relationships (Belarusian and Ukrainian)
Political Concerns (Urdu and Hindi)

5. Sociolinguistics Bidialectal: being capable of speaking two dialects
Bilingualism: the state of having two languages.

Simple grammatical rules
Small inventory of sounds

Used for specific purposes such as trade and religion

8. Sociolinguistics
Creole: Pidgin becomes the mother tongue of a group of people (French creole in Sierra Leone)
The post-creole continuum: varieties that evolves in communities where a creole is spoken.
Creolisation: the process of development from a pidgin to a creole
Decreolisation: use of standard variety instead of creole forms and structures (British English in Jamaica)
Creole accent: pronunciation features
