The a fi page gives you the six forms — sunt, ești, este/e, suntem, sunteți, sunt. This page is about what those forms do. And the headline is striking for an English speaker: a single Romanian verb, a fi, covers three jobs that feel quite distinct — saying who/what something is (identity), saying where it is (location), and saying that it exists (existence). On top of that, a fi powers a whole family of feeling-idioms (mi-e foame, "I'm hungry") and the impersonal expressions of time and judgement (e ora trei, e greu). One verb, an enormous functional range. The one thing it does not do is age and a couple of bodily-state idioms — those belong to a avea, and the boundary is the trap.
Identity and predication: who or what something is
The first and most basic use: linking a subject to a noun or adjective that describes it. This is the copula — a fi as an equals sign between the subject and what it is. English does exactly the same with "be."
Sunt student la Medicină.
I'm a medical student.
Ea este avocată, lucrează la un cabinet din centru.
She's a lawyer, she works at a downtown firm.
Cartea asta e foarte bună, ți-o recomand.
This book is very good, I recommend it to you.
One detail that surprises English and Romance speakers alike: with professions and roles, Romanian normally uses no article after a fi. You say sunt profesor ("I am [a] teacher"), not sunt un profesor, unless you add a describing phrase (sunt un profesor exigent, "I'm a demanding teacher"). The bare noun is the default. (Fuller treatment on copular sentences.)
Sunt profesor de zece ani.
I've been a teacher for ten years. (no article: profesor, not un profesor)
Tata e inginer, mama e medic.
Dad is an engineer, Mum is a doctor. (bare nouns)
Location: where something is
Where English (and Spanish estar) might reach for a special "located" verb, Romanian simply uses a fi again. Sunt acasă = "I'm at home." No separate location verb, no ser/estar decision.
Sunt acasă, vino când vrei.
I'm home, come over whenever you like.
Unde ești? Te aștept de o jumătate de oră.
Where are you? I've been waiting half an hour.
Cheile sunt pe masă, lângă telefon.
The keys are on the table, next to the phone.
This is one place the single-verb design really pays off: the same sunt that says sunt obosit ("I'm tired," a state) says sunt aici ("I'm here," a location). You never stop to pick a verb.
Existence: that something is (there)
The third job is existential — asserting that something exists or is present. Here a fi translates English "there is / there are." Romanian has no dummy "there"; it just uses este / e (singular) or sunt (plural), often with the subject after the verb.
Este o problemă cu comanda ta.
There's a problem with your order.
Sunt mulți oameni la coadă azi.
There are a lot of people in the queue today.
E cineva acasă?
Is anyone home?
Notice the agreement: este/e o problemă (one thing, singular verb) but sunt mulți oameni (many things, plural verb). This is the same a fi, now meaning "exists / is present." (For the full pattern, including există, see there is / existential.)
The mi-e feeling-idioms: a fi + dative
This is one of the most characteristic constructions in Romanian, and it runs entirely on a fi. To say you are hungry, cold, sleepy, afraid, hot, thirsty — bodily and emotional states — Romanian says, literally, "to me is hunger / cold / sleep." The verb is e (from este), and a dative pronoun marks who feels it: mi-e foame = "to-me is hunger" = "I'm hungry."
| Romanian | Literal | English |
|---|---|---|
| mi-e foame | to-me is hunger | I'm hungry |
| mi-e sete | to-me is thirst | I'm thirsty |
| mi-e frig | to-me is cold | I'm cold |
| mi-e somn | to-me is sleep | I'm sleepy |
| mi-e frică / teamă | to-me is fear | I'm afraid |
The dative pronoun changes for the person who feels the state: mi-e (to me), ți-e (to you), i-e (to him/her), ne e (to us), vă e (to you pl.), le e (to them).
Mi-e foame, hai să comandăm o pizza.
I'm hungry, let's order a pizza.
Ți-e frig? Închid fereastra.
Are you cold? I'll close the window.
Copilului i-e somn, îl culc acum.
The child is sleepy, I'll put him to bed now. (i-e = to him)
The deep point: these states are not framed as something the subject is (sunt foame is impossible) nor something they have — they are framed as something that is, to them. The "real subject" grammatically is foame (hunger); you are the dative experiencer. Once you see the pattern, the whole family is one construction. (See feelings and states for the full inventory.)
Time, weather, and impersonal judgements
A fi also carries the impersonal e used for clock time, and for evaluative statements ("it's hard / easy / important to…"). There is no subject — e stands alone as a dummy.
E ora trei, ar trebui să plecăm.
It's three o'clock, we should get going.
E frumos afară, ieșim la o plimbare?
It's nice out, shall we go for a walk?
E greu să înveți o limbă nouă, dar merită.
It's hard to learn a new language, but it's worth it.
These impersonal e + adjective patterns (e greu, e ușor, e important, e posibil) typically introduce a să-clause and are extremely common. The e here means roughly "it is" with no real "it."
The boundary: where a avea takes over
Now the trap. Because a fi does so much, English speakers over-extend it — especially to age. In Romanian, age is possession: you have years, you are not them. Am douăzeci de ani ("I have twenty years"), never sunt douăzeci de ani. And the feeling-idioms split: hunger/cold/sleep use a fi + dative (mi-e foame), as above, but the amount and a few states lean on a avea elsewhere. The safe rule: age is always a avea (am … ani), and the mi-e states are always a fi + dative (mi-e foame). See uses of a avea for the other side.
Am douăzeci și cinci de ani.
I'm twenty-five (years old). (a avea — not sunt!)
Câți ani ai? — Sunt încă tânăr, am douăzeci.
How old are you? — I'm still young, I'm twenty.
Common Mistakes
❌ Sunt douăzeci de ani.
Incorrect — age uses a avea: Am douăzeci de ani. (sunt … ani sounds like 'there are … years').
✅ Am douăzeci de ani.
I'm twenty years old.
❌ Sunt foame.
Incorrect — hunger is a fi + dative: Mi-e foame. You can't be 'hunger' with a subject.
✅ Mi-e foame.
I'm hungry.
❌ Sunt un profesor.
Usually wrong — professions take no article after a fi: Sunt profesor. (Add the article only with an adjective: sunt un profesor bun.)
✅ Sunt profesor.
I'm a teacher.
❌ Acolo are o problemă. (using a avea for 'there is')
Incorrect — existence uses a fi: Este o problemă. (a avea is 'to have', not 'there is'.)
✅ Este o problemă.
There's a problem.
❌ Mi-e ora trei. (adding a dative to clock time)
Incorrect — clock time is impersonal e with no dative: E ora trei.
✅ E ora trei.
It's three o'clock.
Key Takeaways
- One verb, a fi, covers identity (sunt profesor), location (sunt acasă), and existence (este o problemă / sunt mulți).
- Professions take no article after a fi: sunt medic, not sunt un medic (unless an adjective follows).
- The mi-e idioms (mi-e foame, frig, somn, frică) are a fi
- a dative experiencer — "to-me is hunger."
- Impersonal e handles time (e ora trei), weather (e frumos), and judgements (e greu să…).
- The boundary with a avea: age is always a avea (am … ani), never sunt … ani.

Covers predicate nouns, adjectives, and adverbials, the present forms of a fi, and negation (nu e / nu sunt).
- Existential Sentences (Este / Sunt / Există)A2 — How to say 'there is / there are' in Romanian — which has no 'there' dummy at all. Use este/e for singular, sunt for plural (Este o problemă; Sunt multe probleme), agreeing with the thing that exists; există is the more formal/abstract option. The verb usually comes first (E cineva la ușă?). Negation uses nu e nimeni / nu există. The big trap: do not invent a 'there' word and do not freeze the verb as singular for plural things.
