The five major Western sprachräume (by number of speakers) are those of English, Spanish, French, Portuguese, and German.
The English Sprachraum (Anglosphere) spans the globe from the United Kingdom, Ireland, United States, Canada, Australia, and New Zealand to the many former British and American colonies in which English has official language status alongside local languages, such as India, South Africa, and the Philippines.
It includes French-speaking Europe (France, southern Belgium, western Switzerland, Monaco, and Luxembourg), along with Francophone Africa, Quebec in Canada, parts of the United States (Louisiana and northern New England), French Caribbean, and some other former French colonies such as the former Indochina and Vanuatu.
The Lusophony spans Portugal, Brazil, Lusophone Africa, East Timor, and Macau.
A classic example is the varieties of Chinese, which can be mutually unintelligible in spoken form but are typically considered the same language (or at least closely related) and have a unified non-phonetic writing system.
