Context paragraphs:
Older Southern American English: Older Southern American English was a set of American English dialects of the Southern United States, primarily spoken by White Southerners up until the American Civil War, moving towards a state of decline by the turn of the nineteenth century, further accelerated by World War II and again, finally, by the Civil Rights Movement.  These dialects have since largely given way, on a larger regional level, to a more unified and younger Southern American English, notably recognized today by a highly unique vowel shift and certain other vocabulary and accent characteristics.  Some features unique to older Southern U.S. English persist today, though typically in only very localized dialects or speakers.

Walt Wolfram: Walt Wolfram (born February 15, 1941) is a sociolinguist at North Carolina State University, specializing in social and ethnic dialects of American English.  He was one of the early pioneers in the study of urban African American English through his work in Detroit in 1969.  Since the 1960s he has authored or co-authored 20 books and more than 300 articles on variation in American English.  He was an active participant in the 1996 debate surrounding the Oakland Ebonics controversy, supporting the legitimacy of African American English as a systematic language system.  In addition to African American English, Wolfram has written extensively about Appalachian English, Puerto Rican English, Lumbee English, and on many dialects of North Carolina, particularly of rural, isolated communities such as Ocracoke Island.

Jumper (dress): A jumper or jumper dress (in American English), pinafore dress or informally pinafore (British English) is a sleeveless, collarless dress intended to be worn over a blouse, shirt or sweater.  In British English, the term "jumper" describes what is called a "sweater" in American English.  Also, in more formal British usage, a distinction is made between a pinafore dress and a pinafore.  The latter, though a related garment, has an open back and is worn as an apron.  In American English, "pinafore" always refers to an apron.

North American English: North American English (NAmE, NAE) is the most generalized variety of the English language as spoken in the United States and Canada.  Because of their related histories and cultures and the similarities between the pronunciation, vocabulary, and accent of American English and Canadian English, the two spoken dialects are often grouped together under a single category.  Due to historical and cultural factors, Canadian English and American English retain numerous distinctions from each other, with the differences being most noticeable in the two languages' written forms.  Canadian spellings are primarily based on British usage as a result of Canada's longer-standing connections with the United Kingdom.  Canadians are generally tolerant of both British and American spellings, with British spellings being favoured in more formal settings and in Canadian print media.  Spellings in American English have been highly influenced by lexicographers like Noah Webster, who sought to create a standardized form of English that was independent of British English.  Despite these differences, the dialects of both Canada and the United States are similar.  The United Empire Loyalists who fled the American Revolution have had a large influence on Canadian English from its early roots.

Polka Marina: Polka Marina is a Merry-go-round in amusement park Efteling in the Netherlands.  It started operating in 1984.

Carousel: A carousel (American English: from French "carrousel" and Italian "carosello"), roundabout (British English), or merry-go-round, is an amusement ride consisting of a rotating circular platform with seats for riders.  The "seats" are traditionally in the form of rows of wooden horses or other animals mounted on posts, many of which are moved up and down by gears to simulate galloping, to the accompaniment of looped circus music.  This leads to one of the alternative American names, the galloper.  Other popular names are jumper, horseabout and flying horses.

Charles Boberg: Charles Boberg is a researcher and educator in the field of sociolinguistics, specializing in language variation and change, dialectology, and North American English.  He studied at the University of Pennsylvania under seminal sociolinguist William Labov, and is one of the major contributors to the Atlas of North American English, along with Labov and Sharon Ash.  His ongoing research primarily uses acoustic phonetics to analyze differences in the sound patterns of English spoken in North America, and has led to a greater understanding of regional dialects, including those of Western American English, New England English, and Canadian English, often specifically as it's spoken in Montreal.  Boberg is an enthusiastic supporter of the uniqueness of Canadian English, and has been consulted on matters of national security because of his expertise with identifying regional accent and vocabulary patterns.  He is currently Associate Professor of Linguistics at McGill University.

Slot machine: A slot machine (American English), informally fruit machine (British English), puggy (Scottish English slang), the slots (Canadian and American English), poker machine (or pokies in slang) (Australian English and New Zealand English) or simply slot (American English), is a casino gambling machine with three or more reels which spin when a button is pushed.  Slot machines are also known as one-armed bandits because they were originally operated by one lever on the side of the machine as distinct from a button on the front panel, and because of their ability to leave the player in debt and impoverished.  Many modern machines are still equipped with a legacy lever in addition to the button.

North American English regional phonology: North American English regional phonology is the study of variations in the pronunciation of spoken North American English (English of the United States and Canada), though studies of regional dialects can be based on multiple factors, including phonological (abstract sound-based), phonetic (physical sound-based), lexical (vocabulary-based), and some syntactic (grammar-based) factors.  North American English includes American English, which has several highly developed and distinct regional varieties, along with the closely related Canadian English, which is more homogeneous.  American English (especially Western dialects) and Canadian English have more in common with each other than with varieties of English outside North America.

Mid-Atlantic American English: Mid-Atlantic American English, Middle Atlantic American English, or Delaware Valley English is a class of American English, considered by the "Atlas of North American English" to be a single dialect, spoken in the southern Mid-Atlantic states of the United States (i.e. the Delaware Valley, southeastern Pennsylvania, South Jersey, Delaware, and Maryland).
