Cultural diversification and globalisation are causing a meteoric change in accents and dialects across the UK, and indeed the world.  The numerous accents from various regions of the UK that were expected to die out are now flourishing anew with several foreign influences.  It is Received Pronunciation that is actually experiencing a decline, because of the amalgamation of new dialects in the cultural melting pot that the UK has become.

Everywhere in the world has its own unique dialect, and the UK is one of the most diverse nations in the world when it comes to language.  Each region in England has a very unique dialect, and now they are being infused with foreign influences such Creole, Australian, mainland European and a variety of Asian dialects.

New accents are slowly integrated into original regional accents, as immigration introduces people of different cultural backgrounds.  As people interact with others, they learn and sometimes adopt features of each other’s dialects, which is how new dialects are formed.

Many dialects have changed to the degree that entirely new terms, never before used in English language, have been infused into them.  Slang words such as ‘waste man’ (useless person), and sick (great or awesome) both come from Caribbean slang, while ‘stoked’ (excited) comes from Australia, and anime (Asian animated shows) is native to East Asia.

It has been predicted that in one hundred years, English will become a global language known as Panglish, which could be adopted by as many as two billion people.  This phenomenon is being caused by the amalgamation of English with the native languages of those who speak English as a second language.  However, it should be noted that this a not a new concept, considering that Latin forms the basis of almost every language spoken in Europe.  Language is constantly in a cycle of change, and these phenomena reflect its ephemeral nature.
