Common English mistakes Indian speakers make

Every language community has its own habits in English. Ours are consistent enough that once you know them, you can hear yourself making them.

None of these make you wrong. They make you identifiable, and a few make you harder to follow. Those are the ones worth attention.

"I am having" for things you own

✗ I am having two children.
✓ I have two children.

The continuous form is for actions, not possession. I am having lunch is correct. I am having a car is not. This one is extremely common and very quick to fix.

"Doubt" when you mean "question"

✗ Ma'am, I have a doubt.
✓ Ma'am, I have a question.

In Indian English doubt means question. Elsewhere it means suspicion — so "I have a doubt about your report" sounds like you distrust it. Fine at home, worth changing in an interview.

The missing article

✗ I am going to market.
✓ I am going to the market.

Hindi and Punjabi have no articles, so a, an and the get dropped. This rarely blocks understanding but it is the single clearest marker of a non-native speaker.

"Revert" for "reply"

✗ Please revert with the details.
✓ Please reply with the details.

Revert means to go back to a previous state. It's near-universal in Indian offices and puzzling everywhere else.

Prepone

A genuinely useful word that only exists in Indian English. Outside India, say move it earlier.

"Only" in the wrong place

✗ I came yesterday only.
✓ I only came yesterday.

The question tag

✗ You are coming, no?
✓ You are coming, aren't you?

"Kindly do the needful"

Perfectly clear in India, archaic elsewhere. Say what you actually want done.

Which of these matter

If you are speaking to Indian colleagues, almost none. If you are in an interview, on a call with a foreign client, or writing to someone abroad, the first four are worth deliberate practice.

Change one a week. Trying to fix all eight at once just makes you self-conscious, and self-conscious is slower than wrong.
