Romanian offers several ways to express alternatives, and laid out as a paradigm they form a tidy system: a default "or" (sau), a more formal "or" (ori), three correlative "either…or" pairs (sau…sau, ori…ori, fie…fie), and a negative "neither…nor" (nici…nici). This page is the systematic inventory — the forms, what register each carries, how the correlative pairs work, and the one agreement rule that surprises every English speaker: nici…nici forces the verb to stay negated. (If what you want is a step-by-step decision between sau, ori, and fie in a specific sentence, the sau vs ori vs fie decision guide walks through that; here we map the whole field and its grammar.)
The paradigm at a glance
| Form | Meaning | Register | Notes |
|---|---|---|---|
| sau | or | neutral, all registers | the default; never wrong |
| ori | or / either | faintly formal, literary | at home in correlatives |
| sau…sau | either…or | neutral | correlative; leans exclusive |
| ori…ori | either…or | formal/emphatic | correlative; "no third way" |
| fie…fie | either…or / whether…or | emphatic, somewhat formal | weighed alternatives; concession with că |
| nici…nici | neither…nor | neutral | negative; verb stays negated |
sau — the default "or"
sau is the unmarked, all-register "or". Use it for a simple choice between two things in conversation or writing; if you only need one "or" word, this is it.
Vrei cafea sau ceai?
Do you want coffee or tea? (neutral, everyday)
Putem pleca azi sau mâine, cum îți convine.
We can leave today or tomorrow, whatever suits you. (neutral)
ori — the more formal "or", and the correlative "either"
ori means the same as sau but reads as a touch more formal or literary. As a single connective it sounds slightly elevated in casual speech; its natural home is the correlative ori…ori ("either…or").
Îți las cheia la vecini ori ți-o pun sub preș.
I'll leave the key with the neighbours or put it under the mat. (single ori — a notch more formal than sau)
Ori vii cu noi acum, ori rămâi singur aici.
Either you come with us now, or you stay here alone. (correlative ori…ori — insistent, 'no third way')
The correlative pairs: sau…sau, ori…ori, fie…fie
A correlative repeats the connective before each alternative, framing them as a closed set — "one of these, take your pick". All three pairs do this; they differ in register and emphasis. sau…sau is the neutral correlative; ori…ori is more formal and insistent; fie…fie presents the alternatives as deliberately weighed options.
Sau termini proiectul azi, sau pierzi clientul.
Either you finish the project today, or you lose the client. (sau…sau, neutral correlative)
Premiul poate fi acordat fie unui scriitor, fie unui poet.
The prize may be awarded either to a writer or to a poet. (fie…fie, weighed alternatives, slightly formal)
Ne vedem fie luni, fie miercuri — alege tu.
We'll meet either Monday or Wednesday — you choose. (fie…fie, balanced options)
The hallmark of a correlative is that it comes in pairs: you cannot front-load ori or fie and then drop it on the second branch. Both slots must be filled.
fie…fie has a second, distinct job: with the conjunction că it becomes the concessive "whether…or", where the alternatives lead to the same outcome — Fie că plouă, fie că e soare, mergem ("Whether it rains or it's sunny, we're going"). That concessive use is something sau and ori cannot do; it is covered alongside the decision logic on the choosing page.
Fie că vrei, fie că nu, trebuie să mergi la dentist.
Whether you want to or not, you have to go to the dentist. (fie că…fie că = concession)
Exclusive vs inclusive readings
None of these is the logician's strict exclusive-or, but they tilt differently. A single sau is the most inclusive/neutral — "coffee or tea" doesn't strictly forbid both. The doubled correlatives ori…ori and fie…fie lean clearly exclusive ("one or the other, not both, no third way"), which is part of why they feel emphatic. So if you need to force a single choice, the correlative is the stronger tool.
Vrei și cafea, și ceai? — Da, sau, de fapt, doar apă.
Do you want both coffee and tea? — Yes, or, actually, just water. (single sau, loose/inclusive)
Ori accepți condițiile, ori semnăm cu alt furnizor — nu există cale de mijloc.
Either you accept the terms, or we sign with another supplier — there's no middle ground. (ori…ori, firmly exclusive)
nici…nici — "neither…nor" and obligatory negative concord
The negative counterpart of "either…or" is nici…nici ("neither…nor"), and it carries the single most important grammar point on this page. In English, "neither…nor" takes a positive verb: "Neither Ion nor Maria is coming." In Romanian the verb must stay negated with nu, because nici is itself a negative word and Romanian has negative concord — when one negative element appears, every negative element in the clause agrees in negativity, including the verb (see negative polarity and concord).
Nu vine nici Ion, nici Maria.
Neither Ion nor Maria is coming. (note the obligatory nu on the verb)
Nu beau nici cafea, nici ceai dimineața.
I drink neither coffee nor tea in the morning. (nu kept despite the 'neither…nor')
Nu mi-a scris și nici nu m-a sunat.
He neither wrote to me nor called me. (each branch negated; nici reinforces the negation)
The pattern to burn in: wherever English says "neither…nor" with a bare positive verb, Romanian keeps the nu. Dropping it (Beau nici cafea, nici ceai) is ungrammatical — the clause has a negative correlative but a positive verb, which Romanian's concord system does not allow. nici on its own also means "not even / nor" (Nici nu vreau să aud — "I don't even want to hear"), and it always co-occurs with clause negation.
Nici Ion nu a venit.
Not even Ion came. (nici + obligatory nu)
Common Mistakes
Dropping the verb's nu with nici…nici (the classic English-transfer error):
❌ Beau nici cafea, nici ceai.
Incorrect — Romanian keeps the verb negated under negative concord: Nu beau nici cafea, nici ceai.
✅ Nu beau nici cafea, nici ceai.
I drink neither coffee nor tea.
Leaving a correlative half-formed (only the first branch marked):
❌ Ori vii cu noi, rămâi acasă.
Incorrect — the second branch also needs its connective: Ori vii cu noi, ori rămâi acasă.
✅ Ori vii cu noi, ori rămâi acasă.
Either you come with us, or you stay home.
Using bare fie as a one-word "or" (it must be doubled, or use sau):
❌ Vrei suc fie apă?
Incorrect — fie needs a partner (fie…fie) or just use sau: Vrei suc sau apă?
✅ Vrei suc sau apă?
Do you want juice or water?
Using sau…sau for the "whether…or" concession (that is fie că…fie că):
❌ Sau vrei, sau nu, tot mergem.
Incorrect — the 'whether or not' concession uses fie că…fie că: Fie că vrei, fie că nu, tot mergem.
✅ Fie că vrei, fie că nu, tot mergem.
Whether you want to or not, we're still going.
Pairing nici with a non-negative partner instead of a second nici:
❌ Nu vine nici Ion sau Maria.
Incorrect — under negation the second alternative also takes nici, not sau: Nu vine nici Ion, nici Maria.
✅ Nu vine nici Ion, nici Maria.
Neither Ion nor Maria is coming.
Key Takeaways
- sau is the neutral default "or"; ori is the same but faintly formal and the natural correlative partner.
- The correlatives sau…sau / ori…ori / fie…fie ("either…or") are obligatorily paired and lean exclusive ("no third way"); fie…fie also gives the deliberate "weighed alternatives" feel.
- fie că…fie că uniquely expresses the concessive "whether…or" — sau and ori can't do this.
- nici…nici ("neither…nor") keeps the verb negated (Nu vine nici Ion, nici Maria) because nici triggers Romanian's obligatory negative concord — the opposite of English's positive-verb "neither…nor".

- Conjunctions: An OverviewA1 — A map of the Romanian conjunction system — the coordinators (și, sau/ori, dar/iar/însă, deci, nici) that join equals, and the subordinators (că, să, dacă, când, pentru că, deși) that hang one clause off another. The organizing insight is the că vs să split: că introduces asserted facts and takes the indicative, while să introduces wanted, possible, or commanded actions and takes the conjunctiv — the very same fact/non-fact decision that runs the whole mood system.
- Coordinators: și, iar, dar, însă, ciA2 — The Romanian coordinators that English flattens into 'and' and 'but'. și is plain 'and'; iar is a contrastive 'and' meaning roughly 'whereas' (Eu citesc, iar el doarme). Romanian then has three words for 'but': dar (the general one), însă (more formal, and unusually able to move inside the clause), and ci (the corrective 'but rather', which is obligatory after a negation: Nu e roșu, ci albastru).
- sau vs ori vs fieB1 — Choosing the right Romanian 'or' — sau as the neutral default, ori as the bookish/correlative option, fie…fie for explicit alternatives and 'whether…or'.
- Negative Polarity and Concord in DepthC1 — Romanian's negative words (nimic, nimeni, niciodată, nicăieri, niciun, nici) are strict negative-concord items: they demand the clausal nu even when they already mean 'nothing/nobody' (Nu vine nimeni). This page maps the full n-word set, the obligatory-nu rule, their behavior in non-veridical contexts (questions, conditionals, comparatives like mai mult decât oricând), and the positive-vs-negative polarity split (cineva/ceva vs nimeni/nimic) conditioned by veridicality — far subtler than 'double negation'.
