Siyi Yue has a representative dialect that is related to what larger language?
Taishanese Taishanese, or in the Cantonese romanization Toishanese (; Taishanese: ] ), is a dialect of Yue Chinese. The dialect is related to and is often referred to as Cantonese but has little mutual intelligibility with the latter. Taishanese is spoken in the southern part of Guangdong Province in China, particularly around the city-level county of Taishan located on the western fringe of the Pearl River Delta. In the late 19th century and early 20th century, a significant amount of Chinese emigration to North America originated from this four-counties area called Sze Yup, making Toishanese a dominant variety of the Chinese language spoken in Chinatowns in Canada and the United States. It was formerly the lingua franca of the overseas Chinese residing in the United States.
Sinophone Chinese-speaking world or Sinophone or sinophone is a neologism that fundamentally means "Chinese-speaking", typically referring to a person who speaks at least one variety of Chinese. Academic writers use Sinophone "Chinese-speaking regions" in two ambiguous meanings: either specifically "Chinese-speaking areas where it is a minority language, excluding China and Taiwan" or generally "Chinese-speaking areas, including where it is an official language". Many authors use the collocation Sinophone world to mean the overseas Chinese regions of diaspora outside of Greater China, and some for the entire Chinese-speaking world. Mandarin Chinese is the most commonly spoken language today, with over one billion people, approximately 20% of the world population, speaking it.
