English, Hinglish or Tanglish????? Ask the Oxford Dictionary.

My dear Satchi
I am also plagued by similar linguistic concerns but I do not scratch my head beyond a point. My reluctance to scratch my head heavily is out the fear that the outer layer may get peeled off exposing any unsavoury marks that can put me off. Remember the second episode of the Omen series? The young hero discovers that his scalp bears the numbers ‘666’ and realises that he is the anti-Christ and gets a shock of his life. Having spent seven decades of quiet life, I am not mentally prepared for any such eventuality and so I generally leave my head unscratched no matter how strong the urge may be.

You ask what is correct English but I do not understand the need for this question. Correct English is now a myth with each nation following its own version of the language. Their pronunciation is so disparate that the urge to scratch the head becomes overwhelming. When an Australian refers to the day in progress, he pronounces it as ‘to-die’ leaving you wondering why he is suddenly bringing the subject of death in an ordinary conversation. So it would be difficult to say whose English is ‘correct’. England may be the home of English but even there, there is so much of variety in the English spoken among various communities that even a well-bred Englishman would find it difficult to understand it, as my favourite Professor Higgins laments in My Fair Lady:

Dropping "h's" everywhere.
Speaking English anyway they like.
You sir, did you go to school?
Man Wadaya tike me for, a fool?
No one taught him 'take' instead of 'tike!
Why can't the English teach their children how to speak?

The famous saying that ‘there is nothing good or bad; only thinking makes it so’ applies to Languages as well. If you hear some of the sentences spoken by popular world leaders, you would know what I mean. I have already pointed out the ‘Foot in the mouth Award’ given annually in one of my FBs elsewhere. For example, George Bush got the Award for this sentence of his:
“I know what I believe. I will continue to articulate what I believe and what I believe – I believe what I believe is right."
He is the father of many such dramatic sentences!

If the Bard had written all his dramas in acceptable English, there would not have been so many people making a living by trying to explain the Bard’s English and how divergent are their views! My friends in IL know how crazy I am about Wodehouse and I always try to borrow his style particularly during my weak attempts at humour resulting in people critisising me for not speaking simple English!

As you have pointed out, the invasion of local words in English has made the language ridiculously simple. In Tamilnadu, people refer to urgent matters as ‘head going business’. Managing is simplified into ‘samalification’ or ‘samalify’. And the advent of internet has mutated Queen’s English beyond recognition! I guess this is what evolution is all about!
