21 US and British English
21.7 Other varieties of English
Although there is considerable variation in specific vocabulary among varieties of English other than US and British, nearly all varieties of English tend to follow one or the other closely with regard to orthography, grammar, and syntax. Countries that are former British colonies and members of the Commonwealth tend to follow British English, as is also the case for English used within the European Union. Former US colonies (notably the Philippines), Latin America, and other countries with strong cultural or trade relations with the US tend to follow US English. Two main varieties—Canadian and Australian—deserve mention because they both follow British English in some respects and US English in others. When localizing to either of these dialects, it is essential to have specific guidance in the form of a dictionary and a style document to ensure consistency.
