In an article supplied by the brilliant Language Feed (which you can subscibe to here), Ranjita Biswas talks about the way Indians have adapted to the influence of other languages upon their own version of English. As she says in the article:
If the UK takes pride in its multiculturalism, urban Indians are comfortable too with a language from across the seas becoming a part of their own day-to-day life. Indeed, any casual observer of the current social scenario would know that the language, which may not be Queen’s English, has become the communication language among young and old alike.
This article goes well with the Sue Fox research in the article Cockney Translation which looks at the influence of Bengali accent and dialect on East End English.
