Today, there are many regional varieties of the English language, especially in the parts that were once under the strong influence of Britain and America. Although it has developed its own traits, each regional variety shows a tendency to follow either British English or American English. The purpose of this paper is to examine short-term diachronic changes between the two mainstream varieties and the other regional varieties by comparing the data ten years ago and the recent one. It will be demonstrated that the patterns have shifted and linguistic Americanization is underway.
