Is Hinglish the language spoken in India not Hindi? I see Hinglish almost everywhere in India. Just look at the screenshot. In the screenshot, English words that are used in Hindi are: Lock-down, mobile, retailer, recharge, click. Should one learn Hinglish OR Hindi?

When or While? I was swimming when/while he was playing football. While/when I was driving to work I met your brother. She was sleeping when I wrote a letter. Correction please. Thanks!
