Answering 'No' and Contradicting (nu, ba da, ba nu) | Romanian Grammar

Saying "no" in Romanian is the easy half: the answer is nu, the mirror of da ("yes"). The same nu that negates a verb (Nu vin — "I'm not coming") is the word you say to refuse or deny. The hard half — the part with no clean English equivalent — is contradicting a negative. When someone asks "Aren't you coming?" and you mean "Yes, I am!", a plain da will not do the work; you need the contradiction particle ba. Ba da overturns a negative ("yes it is / yes I do"); ba nu emphatically denies a positive ("no it isn't"). English collapses all of this into "yes/no" plus tone of voice. Romanian gives you a dedicated grammatical signal, and using it correctly is one of the clearest markers of a learner who has internalized the system.

💡

The one rule to burn in: to say "yes" against a negative cue, use ba da, never a bare da. After "Aren't you coming?" (Nu vii?), a lone da sounds like you're agreeing with the "not". Ba da! = "Yes I am!" — it flips the expected "no" to "yes". This is the single most common da/nu mistake English speakers make.

nu the answer is the same nu that negates

It helps to see the unity: the word you use to answer "no" is the very same negator you put before verbs. "No, I'm not coming" is Nu, nu vin — the first nu is the answer, the second is the verbal negator. They are one word doing two related jobs: flipping a proposition to false.

— Vii diseară? — Nu, nu pot, am treabă.

— Are you coming tonight? — No, I can't, I'm busy.

— Ai terminat? — Nu încă.

— Have you finished? — Not yet.

So far Romanian and English line up: positive question, da for yes and nu for no. The system only forks when the cue itself is negative.

ba da — overturning a negative

The keystone of this page. When the question or statement contains a negative and you want to assert the positive ("yes, actually it is / yes, I do"), you must use ba da. The particle ba signals "on the contrary"; ba da says "contrary to your 'no', the answer is yes". Romanian shares this with French (si contradicting a negative) and German (doch); English has no such word and resorts to stress: "Yes I AM."

— Nu vii la petrecere? — Ba da, vin, doar întârzii puțin.

— Aren't you coming to the party? — Yes I am, I'm just running a little late.

— Tu n-ai fost niciodată la mare? — Ba da, am fost vara trecută!

— You've never been to the seaside? — Yes I have, I went last summer!

— Nu-ți place cafeaua? — Ba da, îmi place foarte mult.

— Don't you like the coffee? — Yes, I do, I like it a lot.

The logic is sharp: ba da exists precisely because da alone would be heard as confirming the negative. If someone says "You didn't lock the door" and you answer Da, you appear to agree that you didn't. Ba da sets the record straight — "Yes, I did (lock it)."

— N-ai încuiat ușa. — Ba da, am încuiat-o, am verificat de două ori.

— You didn't lock the door. — Yes I did, I locked it, I checked twice.

ba nu — emphatic denial of a positive

The reverse compound, ba nu, contradicts a positive expectation: "no it isn't / no, on the contrary". You reach for it when someone assumes or asserts something positive and you want to firmly push back — including to correct yourself mid-sentence.

— Deci ești de acord cu planul. — Ba nu, tocmai asta voiam să lămuresc.

— So you agree with the plan. — No, actually — that's exactly what I wanted to clear up.

— Tu ai luat ultima felie. — Ba nu, n-am fost eu, jur!

— You took the last slice. — No I didn't, it wasn't me, I swear!

Ba nu is also the everyday way to walk back something you just said — "no wait":

Ne vedem marți... ba nu, miercuri, marți am program.

Let's meet Tuesday... no wait, Wednesday — I'm busy Tuesday.

Use ba nu only when there is something positive to contradict. To a neutral offer like "Want some coffee?" the right refusal is a plain Nu, mulțumesc — there is no claim to overturn, so ba nu would sound oddly combative.

The full picture at a glance

The four-way system depends on two things: whether the cue (question/statement) is positive or negative, and which answer you intend.

The cue	You mean	Say
Positive question — Vii?	yes	Da
Positive question — Vii?	no	Nu
Negative question — Nu vii?	yes, I am (contradicting)	Ba da
Negative question — Nu vii?	no, I'm not (confirming the negative)	Nu
Positive statement you reject	no, that's not so	Ba nu

Read the table's logic: ba only appears when you are going against the polarity of the cue. Agreeing with the cue — even a negative one — uses a plain da or nu. The trap row is the one in bold: a negative question you want to answer "yes" to.

💡

"Confirming" vs "contradicting" is the whole game. To a negative question, if you agree with the negative ("No, I'm not coming"), use plain Nu. If you contradict it ("Yes, I am coming"), use Ba da. Romanian forces you to make that choice grammatically explicit, where English would just say "no" or "yes" and rely on context.

Where the adverb page picks up

This page treats da / nu / ba da / ba nu as the negation system's answer mechanism — how the negator nu also serves as the reply, and how ba reverses polarity. The companion adverbs of affirmation page approaches the same particles from the adverb angle and continues into the full certainty scale — sigur, desigur, poate, probabil, cică — which calibrate how confident your "yes" or "no" is. If you want the graded "of course / maybe / supposedly" layer, that is the page to read next; here we have stayed on the bare yes/no/contradiction core.

Common Mistakes

Answering a negative question with a bare da (the flagship error):

❌ — Nu vii cu noi? — Da, vin!

Confusing — after a negative question, plain da reads as agreeing with the 'no'. Use ba da.

✅ — Nu vii cu noi? — Ba da, vin!

— Aren't you coming with us? — Yes I am, I'm coming!

Using ba da against a positive question:

❌ — Vii diseară? — Ba da.

Odd — there's no negative to contradict; to a positive question just say Da.

✅ — Vii diseară? — Da, sigur.

— Are you coming tonight? — Yes, for sure.

Using ba nu to refuse a neutral offer:

❌ — Vrei o cafea? — Ba nu, mulțumesc.

Combative — nothing to contradict in an offer; a simple nu is right.

✅ — Vrei o cafea? — Nu, mulțumesc.

— Want a coffee? — No, thanks.

Forgetting that confirming a negative still uses plain nu, not ba nu:

❌ — Nu mănânci carne? — Ba nu. (meaning 'correct, I don't')

Wrong — to agree with the negative, say plain Nu; ba nu would mean 'no, that's wrong (I do eat meat)'.

✅ — Nu mănânci carne? — Nu, sunt vegetarian.

— You don't eat meat? — No, I'm a vegetarian.

Key Takeaways

The answer "no" is nu — the very same word that negates verbs; "yes" is da.
To contradict a negative ("yes it is / yes I do"), use ba da — never a bare da, which reads as agreeing with the "not". This is the top da/nu error for English speakers.
ba nu emphatically denies a positive ("no it isn't"), and is the everyday "no wait" for self-correction.
Use ba only when going against the polarity of the cue; agreeing with the cue (even a negative one) takes plain da / nu.
For the certainty scale (sigur, poate, probabil, cică) that grades how confident your answer is, see the adverbs of affirmation page.
