Why I Kept Saying 'I Have a Doubt' and Confusing Everyone

DevGlish Team

During a technical design review, I raised my hand and said: "I have a doubt about the caching strategy."

My American colleague responded: "You doubt it? What's wrong with it?"

That wasn't what I meant at all. I didn't doubt the strategy — I had a question about it. In Indian English, "I have a doubt" simply means "I have a question." It's a direct translation from Hindi, where "mujhe ek doubt hai" is how you'd naturally introduce a question. Every developer I worked with in Bangalore used this phrase daily, and nobody found it odd.

But in American and British English, "doubt" implies skepticism or distrust. "I have a doubt about the caching strategy" sounds like you're questioning whether the strategy is correct or trustworthy. My colleague heard criticism where I intended curiosity.

This was my introduction to L1 interference — the phenomenon where patterns from your first language leak into your second language in ways that change meaning.

The phrases I didn't know were wrong

The "doubt" versus "question" mix-up was just the most visible example. As I started paying attention, I realized I had a collection of phrases that I'd been using for years, that all my Indian colleagues used, and that consistently confused or amused my international teammates.

"Please do the needful." This one is famous. It means "please handle this" or "please take the necessary action." It's standard Indian business English, inherited from British colonial-era correspondence. In modern American or British English, it sounds archaic and vaguely bureaucratic. When I used it in a Slack message, a colleague from London asked if I was "writing a telegram from 1947." He was joking, but the point landed.

"I'll revert to you." In Indian English, "revert" means "respond" or "get back to." "I'll revert to you on this" means "I'll respond to you about this." But in standard English, "revert" means "to return to a previous state" — which in a software context is particularly confusing. When I told my product manager "I'll revert to you after checking the logs," she thought I was going to roll back a deployment.

"Prepone the meeting." The opposite of "postpone." In Indian English, if you move a meeting earlier, you "prepone" it. This word doesn't exist in standard English. The correct phrase would be "move the meeting up" or "reschedule it earlier." When I asked a colleague to "prepone our sync," he had no idea what I meant.

"Today morning" and "yesterday night." In standard English, it's "this morning" and "last night." The pattern of [time word] + [part of day] is natural in Hindi (aaj subah, kal raat) but incorrect in English. This one is subtle — people usually understand what you mean, but it marks you as a non-native speaker immediately.

Why L1 interference is hard to catch

The insidious thing about L1 interference is that the phrases feel completely correct to you. They're not random mistakes or gaps in vocabulary — they're systematic patterns that make perfect sense in your first language. You're not guessing; you're confident. And confidence makes it nearly impossible to self-correct.

It's also reinforced by your environment. If everyone around you says "I have a doubt," you have no reason to think it's unusual. It was only when I started working with non-Indian English speakers that I even noticed these patterns existed. In a room full of Indian developers, "please do the needful" is a perfectly clear instruction.

This is different from pronunciation errors, which you can at least detect by listening to native speakers. L1 interference lives in grammar, word choice, and phrasing — areas where you need someone to explicitly tell you "that phrase means something different than you think" before you even realize there's a problem.

The feedback loop that helped

After the "doubt" incident, I asked my American colleague to flag anything I said that sounded unusual. He agreed, and over the next few weeks, he caught several patterns I'd been blind to:

Having a patient feedback partner was invaluable. But not everyone is lucky enough to have a colleague who's willing to play language coach. This is where tools like DevGlish helped me — it flags L1 interference patterns specific to your native language and explains why the phrase sounds different to other English speakers. Seeing "Indian English speakers often say 'doubt' when they mean 'question'" in a tool felt less personal than being corrected in a meeting.

The identity question

I want to address something that comes up whenever Indian developers discuss L1 interference: the question of identity and code-switching. Indian English is a legitimate variety of English with its own established patterns, much like Australian English or South African English. "Please do the needful" is not wrong — it's Indian English, understood by hundreds of millions of people.

The issue isn't correctness; it's audience. When I communicate with other Indian developers, I use Indian English naturally and comfortably. When I communicate with an international team, I adjust my phrasing to avoid confusion. This isn't abandoning my linguistic identity — it's code-switching, the same thing every multilingual person does multiple times a day.

The goal isn't to "fix" your English or to pretend you're a native speaker. It's to be understood clearly by your specific audience. If your audience is international, certain Indian English patterns will cause confusion, and it's practical to adjust them. If your audience is Indian, use whatever comes naturally.

A practical checklist

For Indian developers working with international teams, here are the most common L1 patterns worth adjusting:

You don't need to memorize this list — just be aware that these patterns exist. Once you know they're L1 interference rather than standard English, you'll start catching them naturally. And when you catch yourself saying "I have a doubt," you can smile, correct to "I have a question," and move on. It gets easier every time.
