Saying "thank you" or "sorry" in Romanian is never one word — it's a choice along a ladder, from casual to formal, from light to heavy. The skill isn't knowing the words; it's matching the weight of the phrase to the weight of the situation. Thank a bank clerk with the breezy Mersi and you sound under-dressed for the occasion; apologize for stepping on someone's foot with the heavy Îmi pare rău and you sound like you're mourning. This page lays out both ladders and teaches you to read which rung a situation calls for. (For the bare formula list, see greetings and politeness formulas; for the register reasoning behind te / vă, tu vs dumneavoastră. Here: choosing the right rung.)
The gratitude ladder
From most casual to most formal:
| Phrase | Weight / register | Use with |
|---|---|---|
| Mersi | (informal) — breezy, French loan | friends, peers, family, casual settings |
| Mulțumesc | neutral — the all-purpose default | almost anyone, safe everywhere |
| Mulțumesc frumos / mult | warm, intensified | genuine, fuller thanks to anyone |
| Vă mulțumesc | (formal) — polite vă | strangers, elders, officials, superiors |
| Vă mulțumesc frumos / din suflet | formal + warm/heartfelt | real gratitude in a formal relationship |
Mersi is borrowed from French merci and is casual — extremely common in everyday speech among friends, but lightweight, and out of place in formal speech or writing. Mulțumesc is the neutral workhorse that's safe almost anywhere. Adding frumos ("nicely") or mult ("much") warms it; switching to vă makes it formal.
Mersi că m-ai așteptat, am întârziat la metrou.
Thanks for waiting for me, I was held up at the metro. (casual, to a friend — Mersi fits)
Vă mulțumesc frumos pentru ajutor, mi-ați salvat ziua.
Thank you very much for your help, you saved my day. (formal + warm — Vă mulțumesc to someone you'd address with dumneavoastră)
Mulțumesc mult, chiar nu trebuia să te deranjezi.
Thanks a lot, you really shouldn't have gone to the trouble. (neutral, warm)
Replying to thanks
The reply is also graded, though less steeply:
| Reply | Force / register |
|---|---|
| Cu plăcere | "you're welcome" (lit. "with pleasure") — the standard default, works everywhere |
| Cu mare plăcere | "with great pleasure" — warmer |
| Pentru puțin | "don't mention it" (lit. "for little") — light, casual |
| N-ai pentru ce / N-aveți pentru ce | "no need to thank me" (informal / formal) — dismissive in the warm sense |
| Cu drag | "gladly / with affection" — warm, between people who like each other |
— Mulțumesc mult! — Cu plăcere, oricând.
— Thanks a lot! — You're welcome, anytime. (the standard reply)
— Mersi că m-ai ajutat! — N-ai pentru ce, lasă.
— Thanks for helping me! — Don't mention it, no worries. (casual)
Note the register match in the reply too: N-ai pentru ce (informal tu) versus N-aveți pentru ce (formal dumneavoastră) — the reply should sit at the same level as the relationship.
The apology ladder
Romanian splits apology into a light branch (excuse-me, small bumps) and a heavy branch (genuine regret, real transgressions), and learners must keep them apart. From lightest to weightiest:
| Phrase | Weight / register | For |
|---|---|---|
| Pardon | (neutral, slightly dated) — French loan | squeezing past, not hearing, a tiny slip |
| Scuze / Scuză-mă / Scuzați-mă | casual / formal — "sorry, excuse me" | bumping someone, interrupting, a minor offense |
| Îmi pare rău | neutral, genuine — "I'm sorry / I regret" | real regret, sympathy, a mistake that mattered |
| Îmi cer scuze | more formal — "I apologize" | a real apology, careful or formal settings |
| Vă rog să mă scuzați | (formal) — "please excuse me" | formal apology to someone you address with vă |
| Iertați-mă | (formal/weighty) — "forgive me" | a serious transgression |
The crucial distinction is between light Scuze / Pardon and heavy Îmi pare rău. Scuze and Pardon are for the small frictions of being among other people — passing through a crowd, interrupting, a trivial slip. Îmi pare rău expresses genuine regret or sympathy — for a real mistake, for someone's loss, for bad news. Using the heavy form for a light bump sounds oddly grave.
Pardon, îmi dați voie să trec?
Excuse me, may I get through? (light — squeezing past in a crowd)
Scuzați-mă că vă întrerup, dar vă caută cineva la telefon.
Sorry to interrupt you, but someone's on the phone for you. (light/formal — interrupting)
Îmi pare rău pentru pierderea suferită, era un om deosebit.
I'm sorry for your loss, he was a remarkable man. (heavy — genuine sympathy)
Vă rog să mă scuzați pentru întârziere, a fost un accident pe șosea.
Please excuse me for being late, there was an accident on the road. (formal apology that matters)
Iartă-mă, n-am vrut să te rănesc cu vorbele alea.
Forgive me, I didn't mean to hurt you with those words. (heavy, intimate — a real transgression, tu form: iartă-mă)
Replying to an apology
When someone apologizes to you, you wave it off:
| Reply | Meaning |
|---|---|
| Nu-i nimic | "it's nothing / no harm done" |
| Nicio problemă | "no problem" |
| Nu face nimic | "it doesn't matter / never mind" |
| Lasă, nu-i nimic | "never mind, it's fine" (warm, dismissive) |
— Scuze că am dat peste tine! — Nu-i nimic, nicio problemă.
— Sorry I bumped into you! — It's nothing, no problem at all.
— Vă rog să mă scuzați pentru deranj. — Nu face nimic, cu ce vă pot ajuta?
— Please excuse the bother. — It's no trouble, how can I help you? (formal context, dismissive reply)
Comparison with English
English overloads "sorry" — it covers excuse-me, genuine regret, sympathy, and even "could you repeat that?" all at once, with tone doing the sorting. Romanian forces you to choose the branch: light Scuze / Pardon versus heavy Îmi pare rău, and the wrong branch is conspicuous. English also has no single dominant "you're welcome" (we scatter across "no problem," "sure," "anytime"), whereas Romanian has a clear default, Cu plăcere. And English "thanks" doesn't carry a built-in register the way Mersi (casual) versus Vă mulțumesc (formal) does — in Romanian the thanks-word itself commits you to a register, so you can't stay neutral.
Common Mistakes
Using casual Mersi with an official or elder:
❌ [to a clerk at a government office] Mersi!
Too casual for the setting — it reads as under-dressed. Use Mulțumesc or Vă mulțumesc.
✅ Vă mulțumesc frumos!
Thank you very much! (formal)
Using heavy Îmi pare rău for a light bump:
❌ Îmi pare rău, pot să trec? [squeezing past in a queue]
Too heavy — Îmi pare rău is real regret. For passing through, say Pardon or Scuzați-mă.
✅ Pardon, îmi dați voie?
Excuse me, may I get through?
Using light Scuze where genuine regret is owed:
❌ [hearing a friend's grandmother died] Scuze.
Far too light for a bereavement — this needs the heavy branch.
✅ Îmi pare tare rău, condoleanțe.
I'm so sorry, my condolences.
Calquing English "you're welcome" as ești binevenit:
❌ — Mulțumesc! — Ești binevenit.
A calque — that means 'you are welcome [to arrive]', a different situation. The reply to thanks is Cu plăcere.
✅ — Mulțumesc! — Cu plăcere!
— Thank you! — You're welcome!
Mismatching the reply's register to the relationship:
❌ [an elderly stranger thanks you] N-ai pentru ce.
Register clash — N-ai pentru ce uses informal tu; to someone formal, use N-aveți pentru ce or Cu plăcere.
✅ Cu plăcere, doamnă.
You're welcome, ma'am. (safe, formal)
Key Takeaways
- Thanks is a register ladder: Mersi (casual) < Mulțumesc (neutral default) < Mulțumesc frumos/mult < Vă mulțumesc (formal). Match the rung to the relationship; Mulțumesc is the safe middle.
- Apology has two branches: light Pardon / Scuze / Scuzați-mă (small bumps, excuse-me) versus heavy Îmi pare rău / Vă rog să mă scuzați / Iertați-mă (real regret, formal apology). Don't cross the branches.
- Reply to thanks with Cu plăcere (default); reply to apologies with Nu-i nimic / Nicio problemă.
- Keep the reply's register matched to the relationship (N-ai pentru ce informal vs N-aveți pentru ce / Cu plăcere formal).
- English overloads "sorry" and "thanks"; Romanian makes you commit to a register and a branch with the word itself.

- Pragmatics: OverviewB1 — The social layer the grammar pages don't teach — how Romanian's obligatory tu/dumneavoastră choice, warmth-carrying diminutives, conditional-based softening, and ritual formulas decide whether perfectly correct Romanian comes across as warm, polite, or rude.
- Greetings and Politeness FormulasA1 — The everyday phrasebook of Romanian courtesy — Bună ziua / Bună seara, Salut / Bună, the regional Servus / Noroc, goodbyes (La revedere, Pa), please and thank you (Vă rog, Mulțumesc, Mersi, Cu plăcere), apologies (Scuze, Îmi pare rău), and Poftă bună. The point is which one to reach for and what register it commits you to — your greeting brands you the instant you open your mouth.
- The Politeness System (T/V) in UseB1 — When Romanians actually choose tu (intimacy, equality) versus dumneavoastră (distance, respect), who is allowed to propose the switch to tu, why dumneavoastră is the safe default with anyone unfamiliar or senior, and where the fading middle form dumneata fits — the social logic behind a choice English speakers don't have to make.
- Conversational Rituals and GreetingsB1 — The social scripts a conversation runs on — the phatic Ce mai faci? that is not a real question, leave-taking chains (Cu bine, Numai bine, Pe curând, Hai, pa), toasts (Noroc!, Sănătate!, Să trăiești!), occasion-wishes (La mulți ani!, Spor la treabă!, Drum bun!, Casă de piatră!), and condolences/congratulations. The principle: these are obligatory rituals, not information exchanges — skipping them reads as cold, and Romanian has a fixed wish for almost every occasion.
- Politeness and IndirectnessB1 — How Romanians soften a request so it doesn't land as a demand — the stacking of conditional verbs (Aș vrea, V-aș ruga), question framing (Ați putea…?), apologetic prefaces (Scuzați că vă deranjez), hedges (cam, puțin, oarecum), impersonal forms (Se poate…?), and diminutives. The social principle: politeness is built by layering distance-creating devices, and a bare Vreau or imperative sounds curt.
- Cultural Context for LearnersA2 — The ritual phrases, titles, and social etiquette a learner needs in Romania and Moldova — name days (onomastica) and La mulți ani!, hand-kissing greetings (Sărut mâna), holiday exchanges (Hristos a înviat! / Adevărat a înviat!), titles (domnule/doamna), and the tu/dumneavoastra distance that decides whether you sound polite or presumptuous.
