Not only India, all have changed English. Americans have made the most changes. 

Every country where English is spoken or given priority, the words of that country's local language are added to the list, so that it becomes easy for them to learn and speak English. 

True. Local languages and internet lingo are mixed with English. An example is, "Where had you been Yar ?" These things are bound to happen. And remember it's used for communication only. This lingo will not be accepted in Literary world.
