IELTS Writing Mistakes Nepali and Bangla Speakers Make: Understanding L1 Interference
Reading time: 12 minutes
If you speak Nepali or Bangla (Bengali) as your first language and you are stuck at Band 5.5 or 6 in IELTS Writing, the problem is probably not your vocabulary or your ideas. It is almost certainly your grammar patterns — specifically, patterns transferred invisibly from your mother tongue into your English.
Nepali and Bangla are both Indo-Aryan languages. They share deep structural features: Subject-Object-Verb word order, postpositions instead of prepositions, no article system, and pro-drop grammar that lets you omit subjects. These features create a remarkably similar set of IELTS writing errors for speakers of both languages.
The good news? Once you can see these patterns, you can fix them. This guide walks through the seven most common L1 interference errors, explains why your brain produces them, and gives you concrete strategies to eliminate them from your writing.

1. SOV Word Order Transfer
Why This Happens
Nepali and Bangla both follow SOV (Subject-Object-Verb) word order. In Nepali, you say "म विद्यालय जान्छु" (ma vidyalaya jaanchu — I school go). In Bangla, you say "আমি স্কুলে যাই" (ami school-e jai — I school go). English uses SVO: "I go to school."
For simple sentences, most Nepali and Bangla speakers handle the conversion automatically. The trouble appears in complex sentences — when you have subordinate clauses, relative clauses, or multiple objects. Your brain reverts to SOV logic under cognitive load.
Incorrect Example
"The government more schools in rural areas should build so that children education can receive."
Corrected Example
"The government should build more schools in rural areas so that children can receive education."
Practice Tip
After writing a complex sentence, identify the main verb. Check that it comes after the subject and before the object. If you find the verb sitting at the end of a clause, restructure.
2. Postposition vs Preposition Confusion
Why This Happens
English uses prepositions — words that come before a noun (in the house, on the table, for the children). Nepali and Bangla use postpositions — markers that come after a noun. In Nepali, "घरमा" (ghar-ma) literally translates as "house-in." In Bangla, "বাড়িতে" (bari-te) works the same way.
This difference creates two kinds of errors: choosing the wrong preposition because you are translating postposition logic, and placing prepositional phrases in unnatural positions within the sentence.
Incorrect Example
"Students are dependent on their parents from financial matters."
Corrected Example
"Students are dependent on their parents for financial matters."
Practice Tip
Build a personal preposition notebook. Every time you discover a preposition error, write down the correct English collocation (dependent on ... for, interested in, responsible for). Prepositions in English are largely idiomatic — you learn them as chunks, not through rules.
3. Article Errors (Missing, Extra, or Wrong)
Why This Happens
Neither Nepali nor Bangla has a definite or indefinite article system comparable to English. Nepali has no equivalent of "a," "an," or "the." Bangla has the suffix "-টা/-টি" (-ta/-ti), which functions somewhat like "the," but its usage rules are completely different from English articles.
The result? You either omit articles entirely, insert them where they are not needed, or choose "a" when "the" is correct (and vice versa). Research into L1 interference consistently shows that speakers from article-free languages make article errors more frequently than any other grammar mistake.
For a deep dive into this specific pattern, read our guide on how Hindi affects IELTS writing — Hindi, Nepali, and Bangla share very similar article-related challenges.
Incorrect Example
"Education is important factor in development of country. Government should invest in education."
Corrected Example
"Education is an important factor in the development of a country. The government should invest in education."
Practice Tip
After completing your essay, do a dedicated article pass. Read each noun and ask three questions: Is this countable? Is it specific or general? Has it been mentioned before? These three questions cover 90% of article decisions. Our guide on 12 IELTS writing mistakes Indian students make covers article rules in practical detail.
4. Subject Dropping (Pro-Drop Transfer)
Why This Happens
Both Nepali and Bangla are pro-drop languages, meaning you can omit the subject when it is understood from context. In Nepali, you can say "जान्छु" (jaanchu — "[I] go") without the pronoun. In Bangla, "যাই" (jai — "[I] go") works the same way. The verb conjugation carries the subject information.
English is not pro-drop. Every clause needs an explicit subject (except imperatives). When you write in English with a Nepali or Bangla thinking pattern, you unconsciously drop subjects — especially in the second or third clause of a long sentence.
Incorrect Example
"Many students study abroad because want better opportunities and can earn higher salaries."
Corrected Example
"Many students study abroad because they want better opportunities and they can earn higher salaries."
Practice Tip
After writing each paragraph, check every clause for a visible subject. If a clause has a verb but no noun or pronoun before it, add the appropriate subject. Pay special attention to sentences with "because," "so that," "which," and "and" — these conjunctions are where subject-dropping most often occurs.
5. Tense-Aspect Confusion
Why This Happens
The tense-aspect systems of Nepali and Bangla do not map neatly onto English. Both languages distinguish between simple, continuous, and perfect aspects, but the boundaries are different. In Bangla, the simple present ("করি" — kori) often covers situations where English would require the present continuous or present perfect. In Nepali, the habitual and progressive are marked differently than in English.
This creates errors where you use the simple present when English requires the present perfect, or the present continuous where English requires the simple present.
Incorrect Example
"I am living in Kathmandu since 2015 and I am studying English since three years."
Corrected Example
"I have lived in Kathmandu since 2015 and I have been studying English for three years."
Practice Tip
Watch for time markers. When you see "since" or "for" in your writing, check that you have used the present perfect (have + past participle) or present perfect continuous (have been + -ing). When you see "every day," "usually," or "always," confirm you have used the simple present, not the continuous.
6. Formal vs Informal Register Mixing
Why This Happens
Both Nepali and Bangla have complex honorific and register systems that do not correspond to the formal-informal distinction in English academic writing. Nepali has three levels of formality (तिमी/तपाईं/हजुर — timi/tapain/hajur), and Bangla has similar distinctions (তুমি/আপনি — tumi/apni). But these are about social hierarchy, not about written academic register.
As a result, Nepali and Bangla speakers often mix conversational English with formal vocabulary in the same essay. You might write a perfectly formal topic sentence and follow it with a colloquial explanation — because in your L1, the concept of "academic register" as a consistent written style does not exist in the same way.
Incorrect Example
"The proliferation of social media has had a profound impact on interpersonal communication. Basically, people are just glued to their phones 24/7 and don't really talk to each other anymore."
Corrected Example
"The proliferation of social media has had a profound impact on interpersonal communication. As a result, face-to-face interactions have declined significantly, with many individuals relying on digital platforms rather than direct conversation."
Practice Tip
After writing your essay, read each sentence and assign it a register: formal or informal. If you find informal sentences mixed into your body paragraphs, rewrite them. Common informal markers to eliminate: "basically," "just," "really," "a lot of," "stuff," "things," contractions (don't, can't), and rhetorical questions.
7. Verbose and Flowery Writing Style Transfer
Why This Happens
Both Nepali and Bangla literary traditions value elaborate, ornate expression. Good writing in these languages often includes extended metaphors, poetic phrasing, and repetition for emphasis. When you transfer this aesthetic into English academic writing, the result is verbose sentences that say in 30 words what could be said in 12.
IELTS examiners reward clarity and precision. The Coherence and Cohesion band descriptor specifically penalises writing that is "unclear" or where "the message is difficult to follow." Flowery writing often scores lower than simple, direct writing — which surprises many South Asian candidates.
Incorrect Example
"In this modern era of the contemporary world that we are living in today, it cannot be denied by anyone that the matter of environmental pollution is indeed a very serious and grave issue which is of utmost importance."
Corrected Example
"Environmental pollution is one of the most serious issues facing the modern world."
Practice Tip
After writing each sentence, count the words. If a sentence exceeds 25 words, look for phrases you can cut. Common culprits: "in this modern era," "it cannot be denied that," "each and every," "in the present scenario," "it is a well-known fact that." Replace these with direct statements.
How to Practise
Fixing L1 interference is not about learning new grammar rules — you probably already know the rules. It is about building awareness of the specific patterns your brain defaults to under pressure.
Step 1: Identify your top three patterns. Write a timed essay and review it specifically for the seven patterns above. Mark every error and categorise it. Most writers have two or three dominant patterns.
Step 2: Do targeted editing passes. After writing any essay, do separate passes for your top error types. One pass for articles. One pass for word order. One pass for register. This is more effective than trying to catch everything at once.
Step 3: Use AI feedback to find blind spots. Your brain literally cannot see some of these errors because they align with your L1 grammar. BandWriteCoach provides AI-powered feedback that flags exactly these kinds of L1 interference patterns, showing you errors you would never catch on your own.
Step 4: Read your writing aloud. Many word order and subject-dropping errors become obvious when you hear them spoken. If a sentence sounds awkward when read aloud, it probably contains an L1 transfer error.
Step 5: Build a personal error log. Track your errors across multiple essays. When you see the same error type appearing three or more times, you know it is an L1 interference pattern that needs dedicated practice — not just awareness.
Stuck at Band 5.5-6.5 and unsure why? Your first language may be creating errors you cannot see. Try BandWriteCoach for AI-powered feedback that identifies L1 interference patterns specific to Nepali and Bangla speakers — so you can fix the errors that are actually holding you back.
