Rhine Franconian (German:    ), or Rhenish Franconian, is a dialect family of West Central German.
 It comprises the German dialects spoken across the western regions of the states of Saarland, Rhineland-Palatinate, northwest Baden-Wurttemberg, and Hesse in Germany.
 It is also spoken in northeast France, in the eastern part of the département of Moselle in the Lorraine region, and in the north-west part of Bas-Rhin in Alsace.
 To the north, it is bounded by the Sankt Goar line (“"das/dat" line”) which separates it from Moselle Franconian; to the south, it is bounded by the Main line which is also referred to as the "Speyer line" which separates it from the Upper German dialects.
German Brazilians (German: "Deutschbrasilianer", Riograndenser Hunsrückisch: "Deitschbrasiliooner", Portuguese: "teuto-brasileiros" ) refers to Brazilian people of ethnic German ancestry or origin.
 German Brazilians live mostly in the country's South Region, with lesser but still significant degree in the Southeast Region.
 German dialects together make up the second most spoken first language in Brazil after Portuguese.
 A few Brazilian municipalities have Brazilian Hunsrückisch and Germanic Pomeranian as co-official with Portuguese.
 They are located in Southern Brazil and Espírito Santo.
 In the year 2000 Brazilian census 12 million people in Brazil claimed to be of German descent.
Judeo-Berber (Berber: , Hebrew: ברברית יהודית‎ ‎ ) is any of several hybrid Berber varieties traditionally spoken as a second language in Jewish communities of central and southern Morocco, and perhaps earlier in Algeria.
 Judeo-Berber is (or was) a contact language; the first language of speakers was Judeo-Arabic.
 (There were also Jews who spoke Berber as their first language, but not a distinct Jewish variety.)
 Speakers emigrated to Israel in the 1950s and 1960s.
 While mutually comprehensible with the Tamazight spoken by most inhabitants of the area (Galand-Pernet et al. 1970:14), these varieties are distinguished by the use of Hebrew loanwords and the pronunciation of "š" as "s" (as in many Jewish Moroccan Arabic dialects).
Finland Swedish or Fenno-Swedish (Swedish: "finlandssvenska" , Finnish: "suomenruotsi" ) is a general term for the variety of Standard Swedish and a closely related group of dialects of Swedish spoken in Finland by the Swedish-speaking population as their first language.
 For the most part, these dialects and the dialects spoken in Sweden are mutually intelligible, although some archaic Swedish dialects in Ostrobothnia are practically unintelligible to Swedish-speaking people in southern Finland (and in Sweden).
 Most Swedish-speaking Finns emphasize that Finland Swedish is not a language separate from the Swedish of Sweden.
 The Swedish dialects in Finland are considered varieties of Swedish, and the norm for written Standard Swedish is completely applicable also for Finland Swedish.
 Today, Swedish dialects are spoken in four different regions in Finland: Ostrobothnia, Åland Islands, Southwest Finland and Uusimaa.
South Bergish (German: "Südbergische Dialekte ") or Upper Bergish (German: "Oberbergische Dialekte ") is a group of German dialects of the Bergisches Land Region East of the Rhine and approximately south of the Wupper and north of the Sieg.
 These dialects are part of the Ripuarian group and thus are also called East Ripuarian.
 Ripuarian dialects are also spoken west of the Rhine up to the German border, and in some small areas next to the respective borders in Belgium and in the Netherlands.
 Ripuarian Bergish dialects belong to the Middle German group, and thus are varieties of High German, where they belong to the northmost ones.
 In the North, they border to the East Bergish and the West Bergish aka Low Bergish language groups, which are part of the Low Franconian group like Dutch.
East Central German (German: "Ostmitteldeutsche Dialekte" ) is the eastern, non-Franconian sub-group of Central German dialects, themselves part of High German.
 Present-day Standard German as a High German variant has actually developed from a compromise of East Central (especially Upper Saxon promoted by Johann Christoph Gottsched) and East Franconian German.
 East Central German dialects are mainly spoken in Central Germany and parts of Brandenburg, and were formerly also spoken in Silesia and Bohemia.
The German-based varieties spoken by German Brazilians together form a significant minority language in Brazil.
 "Brazilian German" is strongly influenced by Portuguese and to a lesser extent by Italian dialects as well as indigenous languages.
 German dialects are particularly strong in Brazil's South and Southeast Regions.
 According to Ethnologue, ca. 3 million people in Brazil speak Riograndenser Hunsrückisch, 1.5 million Standard German and 8,000 Plautdietsch.
A peanut butter bun is a Hong Kong sweet bun found in Hong Kong as well as Chinatown bakery shops.
 The bun has layers of peanut butter fillings, sometimes with light sprinkles of sugar mixed with the peanut butter for extra flavor.
 Unlike other, similar buns, the shape varies, depending on the bakery.
A lotus seed bun is a Chinese sweet bun found in China.
 They're prepared by steaming a yeast-leavened dough that contains lotus seed paste.
 It can be classified as a dim sum, though not exclusively so.
 They're sometimes available in overseas Chinatowns.
Schnecken are a type of sweet bun that was a traditional Saturday morning treat in German homes at the beginning of the 20th century and that was commonly found in Jewish immigrant communities in the United States (Philadelphia and Baltimore) or German immigrant communities in Southern Brazil (where they're spelled "chineque").
