If you really need evidence of social and cultural globalisation,consider this:
Genuine Indians have often sniggered at the strange food served in Britain's
soi disant or sogenannte(or in English, so-called)'Indian' restaurants which are in fact Bangla Deshi or Pakistani.The reality is ,though, that the curries served in the UK are now British curries -- to be regarded as a separate entity and not as a poor version of authentic Indian cuisine.
Following this logic -- and considering that there are more English-speaking people in India than in any country in the world including Britain,I suggest that Indian English should be accorded the same status as the British curry.Certainly Indian English is no less horrible than Australian or Kiwi English with the difference that Indians play hell with consonants while the antipodeans maul vowels.In fairness, we all have better grammar and spelling than the native Briton.
Think about it...
