Romanian has several ways to talk about the future, and they almost all mean the same thing. The core distinction in one sentence: these are register variants, not meaning variants — you pick the form that fits the situation (casual chat, formal document, emphatic promise), not the form that captures a different shade of futurity. "I'll call you" can be o să te sun, te voi suna, am să te sun, or even just te sun mâine — all true, all future, but each one belongs to a different setting.
This is the trap for English speakers. English has "will" and "going to" with a slight nuance difference (prediction vs intention), so learners assume Romanian's forms must carry comparable nuances. They mostly don't. What changes is how formal you sound. Using voi in a text to a friend sounds stiff and bookish; using o să in a legal contract sounds too casual. Getting the future right in Romanian is 90% about matching register.
The four ways to say it
| Form | Structure | Register | Example |
|---|---|---|---|
| o să | o să + conjunctiv | everyday spoken default | O să te sun. |
| voi | voi/vei/va… + infinitive | formal, written, official | Vă voi informa. |
| am să | am să + conjunctiv | colloquial, emphatic intention | Am să-ți spun. |
| present + adverb | present tense + time word | scheduled near future | Plec mâine. |
o să — the spoken default
If you only learn one future, learn this one. o să + conjunctiv is what Romanians actually say in conversation, the overwhelming majority of the time. The o is invariable (it does not change for person — o să sun, o să suni, o să sune), and the verb goes into the conjunctiv (subjunctive), which differs from the present only in the third person (sune, not sună).
O să te sun diseară, după ce ajung acasă.
I'll call you tonight, once I get home. (informal)
Cred că o să plouă mai târziu, ia o umbrelă.
I think it's going to rain later, take an umbrella. (informal)
N-o să-ți vină să crezi ce mi s-a întâmplat azi!
You won't believe what happened to me today! (informal)
voi — the formal/written future
voi + infinitive is the literary, formal, official future. It is the form you see in newspapers, contracts, speeches, business correspondence, and elevated writing. The auxiliary inflects: voi, vei, va, vom, veți, vor, followed by the short infinitive.
| Person | Form (a suna) |
|---|---|
| eu | voi suna |
| tu | vei suna |
| el / ea | va suna |
| noi | vom suna |
| voi | veți suna |
| ei / ele | vor suna |
Vă vom informa în cel mai scurt timp cu privire la decizia comisiei.
We will inform you as soon as possible regarding the committee's decision. (formal)
Președintele va susține un discurs la ora 18:00.
The president will deliver a speech at 6:00 p.m. (formal, journalistic)
Ne vom strădui să vă oferim cele mai bune servicii.
We will strive to offer you the best service. (formal, business)
am să — colloquial, emphatic intention
am să + conjunctiv is colloquial like o să, but it carries a flavor of personal intention or determination — "I'm going to," as a resolution. Unlike o să, the auxiliary here does inflect (am, ai, are, avem, aveți, au să), and in practice it is most idiomatic in the first and second person singular, where it sounds like a firm promise or a made-up mind.
Am să-ți spun tot, dar promite-mi că nu te superi.
I'm going to tell you everything, but promise me you won't get upset. (informal, emphatic)
Ai să vezi că am avut dreptate.
You'll see that I was right. (informal, with a note of insistence)
Am să mă las de fumat de anul ăsta, m-am hotărât.
I'm going to quit smoking this year, I've made up my mind. (informal, determined intention)
In the third person and plural, am să exists (are să vină, au să plece) but feels more old-fashioned or regional; spoken Romanian prefers o să there. So while o să and am să are both colloquial, am să leans toward the emphatic first-person promise.
present + adverb — the scheduled near future
For a fixed, scheduled, or imminent future, Romanian often just uses the present tense with a time adverb — exactly as English does with "I'm leaving tomorrow" or "the train leaves at six." This is the most casual of all and feels confident, as if the future is already settled.
Plec mâine dimineață la Sibiu.
I'm leaving for Sibiu tomorrow morning. (informal, scheduled)
Filmul începe la opt, ne vedem la cinema.
The film starts at eight, see you at the cinema. (informal, scheduled)
The same sentence across registers
Watch one idea climb the register ladder. The meaning ("I'll send you the documents") does not change; only the social setting does.
Îți trimit documentele mâine.
I'm sending you the documents tomorrow. (most casual — present + adverb)
O să-ți trimit documentele mâine.
I'll send you the documents tomorrow. (everyday spoken default — o să)
Am să-ți trimit documentele mâine, fii fără grijă.
I'll send you the documents tomorrow, don't worry. (colloquial, with a note of promise — am să)
Vă voi trimite documentele mâine.
I will send you the documents tomorrow. (formal, written — voi)
Decision flowchart
| Situation | Use |
|---|---|
| Everyday conversation, texting a friend | o să (default) |
| A firm personal promise or resolution (esp. "I/you") | am să |
| Formal writing, contracts, news, speeches | voi |
| A fixed schedule or imminent plan | present + adverb |
Common Mistakes
English speakers tend to overuse voi because it looks like the "real" future in textbooks, and to mismatch register without realizing it.
Don't use voi in casual conversation — it sounds stiff:
❌ Stai liniștit, te voi suna mai târziu.
Too formal between friends — in casual speech use o să te sun.
✅ Stai liniștit, o să te sun mai târziu.
Don't worry, I'll call you later. (informal)
Don't use o să in a formal document — it sounds too casual:
❌ Prin prezenta, o să vă comunicăm rezultatul.
Too casual for an official notice — use voi: vă vom comunica.
✅ Prin prezenta, vă vom comunica rezultatul.
Hereby, we will communicate the result to you. (formal)
Don't inflect the o in o să — it is invariable:
❌ Ei or să vină mâine.
Incorrect — the o of o să never changes for person; it stays o să.
✅ Ei o să vină mâine.
They'll come tomorrow.
Don't follow o să or am să with an infinitive — they take the conjunctiv:
❌ O să suna când ajung.
Incorrect — o să takes the conjunctiv, and for 1sg that's o să sun.
✅ O să sun când ajung.
I'll call when I arrive.
