How to Say No and Not in Bengali

Why does Bengali put "not" at the end of the sentence instead of the beginning? আমি যাই না (ami jai na, "I don't go") literally reads "I go not," the negative word arriving only after the verb has already done its work. English speakers learning Bengali spend their first few weeks reaching for "not" too early, out of habit, and the sentence comes out garbled. Once the rule clicks, though, Bengali negation turns out to be one of the more forgiving parts of the grammar: a small set of words, a stable position, and almost no irregular exceptions.

This post walks through every piece of that system: where না (na) sits, how it interacts with each tense, the separate word Bengali uses for "there isn't" and "I don't have," and the register shifts that turn a flat refusal into a polite one.

না: The Core Negation Word

না (na, /na/, "not") is the word that does most of Bengali's negating. It comes after the verb, not before it, and it doesn't change form regardless of tense, person, or formality. Compare a positive and negative pair:

• আমি চা খাই। (Ami cha khai.) "I drink tea."
• আমি চা খাই না। (Ami cha khai na.) "I don't drink tea."

The sentence structure stays Subject-Object-Verb straight through; না just tacks on at the very end, after the verb has already been conjugated. This is worth sitting with, because it means you never have to decide how to negate a verb. You conjugate normally, exactly as you would for a positive sentence, and then add না. If you already have a feel for present-tense endings from Bengali verb conjugation in the present tense, you already know everything you need to build the positive half of a negative sentence; this post adds the other half.

One more word worth knowing before the tense breakdown: নয় (noy, /nɔj/, "is not"), which attaches to nouns and adjectives rather than verbs, roughly matching English "is not" in an equational sentence. এটা সহজ নয়। (Eta shohoj noy.) "This isn't easy." You'll see নয় less often than না in daily speech, where আছে/নেই (covered below) usually does the job instead, but it shows up in writing and formal statements.

Negating the Present Tense

In the present tense, না attaches after the fully conjugated verb, whether that verb is in its habitual or continuous form.

Form	Bengali	Romanization	English
Habitual, positive	আমি ভাত খাই	ami bhat khai	I eat rice
Habitual, negative	আমি ভাত খাই না	ami bhat khai na	I don't eat rice
Continuous, positive	আমি কাজ করছি	ami kaj korchhi	I am working
Continuous, negative	আমি কাজ করছি না	ami kaj korchhi na	I am not working

The pronoun endings you already know from the present tense (-i, -is, -o, -en, -e) don't shift under negation. তুমি যাও না? (Tumi jao na?) "Aren't you going?" uses the same -o ending as the positive তুমি যাও (tumi jao, "you go"), with না simply appended. There's no separate negative conjugation to memorize, only one word to place correctly.

Negating the Past Tense

Past tense negation follows the identical pattern: conjugate normally, add না at the end.

Form	Bengali	Romanization	English
Simple past, positive	সে গেল	she gelo	he/she went
Simple past, negative	সে গেল না	she gelo na	he/she didn't go
Past continuous, positive	আমি করছিলাম	ami korchhilam	I was doing
Past continuous, negative	আমি করছিলাম না	ami korchhilam na	I was not doing

There is one genuine wrinkle, and it's worth flagging early because it trips up learners who've gotten comfortable with the present perfect. The present perfect (করেছি, korechhi, "I have done") does not simply add না at the end. Instead, Bengali drops the perfect marker and uses a dedicated negative form built on নি: আমি করিনি। (Ami korini.) "I haven't done it." Compare: আমি খেয়েছি (ami kheyechhi, "I have eaten") negates as আমি খাইনি (ami khaini, "I haven't eaten"), not as kheyechhi na. This is the one place in the system where negation genuinely deviates from "conjugate, then add na." The past tense guide walks through the full positive perfect conjugation these negative forms are built from.

Negating the Future Tense

Future negation returns to the straightforward pattern: conjugate the future normally, append না.

Form	Bengali	Romanization	English
আমি করব	ami korbo	I will do	positive
আমি করব না	ami korbo na	I will not do	negative
আপনি যাবেন	apni jaben	you will go (formal)	positive
আপনি যাবেন না	apni jaben na	you will not go (formal)	negative

তুমি কি আসবে না? (Tumi ki ashbe na?) "Won't you come?" is a construction worth knowing on its own, since in English a negative question like this often signals mild surprise or persuasion ("won't you come?" implies you expected them to). Bengali uses the identical structure for the same effect: question particle কি, future verb, না at the end.

For a complete side-by-side of how negation interacts with every tense-aspect combination, here's the full grid using করা (kora, "to do") in first person:

Tense	Positive	Negative
Present habitual	করি (kori), I do	করি না (kori na), I don't do
Present continuous	করছি (korchhi), I am doing	করছি না (korchhi na), I am not doing
Simple past	করলাম (korlam), I did	করলাম না (korlam na), I didn't do
Present perfect	করেছি (korechhi), I have done	করিনি (korini), I haven't done
Simple future	করব (korbo), I will do	করব না (korbo na), I will not do

Negating Existence and Possession: আছে vs নেই

This is where Bengali negation genuinely parts ways from the "verb plus না" rule, and it's also one of the most useful things to get right early, since "there isn't" and "I don't have" come up constantly in daily life.

Bengali expresses existence and possession with আছে (achhe, "is/exists/is present") rather than a true verb "to have." Possession is phrased as "to me, [thing] exists": আমার একটা বই আছে। (Amar ekta boi achhe.) Literally "to-me a book exists," meaning "I have a book." To negate this, you don't add না after আছে. Instead, the entire word আছে is replaced by নেই (nei, /nei/, "is not/doesn't exist/don't have"):

• আমার টাকা আছে। (Amar taka achhe.) "I have money." (literally: "to-me money exists")
• আমার টাকা নেই। (Amar taka nei.) "I don't have money."
• এখানে কোনো দোকান আছে। (Ekhane kono dokan achhe.) "There is a shop here."
• এখানে কোনো দোকান নেই। (Ekhane kono dokan nei.) "There is no shop here."

তোমার কাছে কলম আছে? না, নেই। তোমার কাছে আছে? (Tomar kache kolom achhe? Na, nei. Tomar kache achhe?) "Do you have a pen on you? No, I don't. Do you have one?"

That short exchange is close to a daily occurrence in Bengali, and it shows the whole system in miniature: a yes/no question built on আছে, a negative answer using নেই on its own (it can stand in as a complete one-word response, much like English "nope"), and the question bounced back.

নেই also negates "to be" when describing presence or location, not just possession. সে বাড়িতে নেই। (She barite nei.) "He/she is not at home" (compare the positive সে বাড়িতে আছে, she barite achhe, "he/she is at home"). This dual duty, covering both possession and simple presence, is why নেই shows up constantly: one word doing the negating for two different English constructions.

Saying No Politely vs Bluntly

Bengali's three-tier pronoun system (covered in full in the post on Bengali pronouns and formality) reshapes how a refusal lands, and negation is one of the places where picking the right register matters most.

A flat না (na) on its own, with no softening, is the bluntest possible "no." Said to a close friend who asks if you want more rice, it's fine, even normal. Said to an elder or a stranger with no cushioning, it can read as curt. Bengali speakers soften a refusal the same way English speakers do: by adding a reason, an apology word, or a gentler construction around it.

না, থাক। (Na, thak.) "No, it's fine" / "No, leave it," a common way to decline an offer (more food, help carrying something) without sounding ungrateful. দুঃখিত, পারব না। (Dukkhito, parbo na.) "Sorry, I won't be able to." এখন না, পরে। (Ekhon na, pore.) "Not now, later," useful for deflecting without a hard refusal.

Formality changes what surrounds the না, exactly as it does everywhere else in the grammar. Declining a request from someone you'd address as আপনি: আমি দুঃখিত, এটা করতে পারব না। (Ami dukkhito, eta korte parbo na.) "I'm sorry, I won't be able to do this." The same refusal to a close friend drops দুঃখিত (dukkhito, "sorry") entirely: এটা পারব না রে। (Eta parbo na re.) "Can't do this, man," where রে (re) is a casual intimate tag with no real English equivalent. The underlying negation, পারব না (parbo na, "won't be able to"), is identical in both; what changes is everything wrapped around it.

Common Negative Expressions and Set Phrases

A handful of negative constructions come up often enough to learn as fixed phrases rather than building from scratch each time.

কিছু না (kichhu na, "nothing" / "it's nothing") answers questions like "what's wrong?" or deflects thanks. কেউ না (keu na, "no one") answers "who's there?" কখনো না (kokhono na, "never") emphasizes a flat refusal over time: আমি কখনো মিথ্যা বলি না। (Ami kokhono mittha boli na.) "I never lie." একদম না (ekdom na, "absolutely not," literally "completely not") intensifies a refusal: এটা একদম ঠিক না। (Eta ekdom thik na.) "This is absolutely not right."

কোনো সমস্যা নেই (kono shomossha nei, "no problem," literally "no problem exists") is the standard reply to an apology or a worry, functionally close to English "no worries." And কোনো দরকার নেই (kono dorkar nei, "there's no need") politely waves off an unnecessary offer: someone insists on paying for your tea, and you answer না না, কোনো দরকার নেই। (Na na, kono dorkar nei.) "No no, there's no need."

Where English Habits Lead You Astray

The single most common mistake is word order: English speakers instinctively want to put "not" before the verb ("I do not go") and end up producing আমি না যাই, which isn't how a Bengali speaker would phrase it. The fix is mechanical: finish the verb first, then add না.

The second mistake is applying না where নেই is required. Because English uses "not" for both "I do not eat" and "I do not have," learners often try আমার বই আছে না to mean "I don't have a book." That isn't correct Bengali; আছে has to be fully replaced by নেই, not negated in place. If you catch yourself writing আছে না to mean "doesn't have," swap in নেই.

The third, subtler mistake involves the present perfect. English speakers who've learned "verb plus na" as the universal rule try to negate করেছি (korechhi, "I have done") as korechhi na, when the correct form drops the perfect marker entirely and uses করিনি (korini, "haven't done"). This one takes deliberate practice because the regular pattern genuinely doesn't apply here, and your ear has to learn the exception the way it learns an irregular verb in any language.

A smaller trap: don't confuse না with নয় (noy, "is not," for nouns and adjectives) or with the suffix নি in করিনি. The three look close enough on paper to blur together early on, but each has a fixed job, and native speakers notice immediately when one gets swapped for another.

Building the Instinct

The good news is that Bengali negation, outside the present-perfect exception, is really just one word placed in one position. Most of the work is building the habit of finishing your verb before you reach for না, the opposite order from English, and that habit comes from repetition more than memorization. Say the positive sentence first, out loud, then add না and say the whole thing again. Do that with five or six verbs across present, past, and future, and the placement stops being something you calculate. The Brightwood Apps Learn Bengali app threads negation through its early units using exactly this kind of paired practice, so you hear আছে and নেই contrasted directly with native-speaker audio rather than learning the rule as an abstract statement.
