Expressing Need (a avea nevoie de, a-i trebui) | Romanian Grammar

Romanian has two main ways to say "I need," and they look nothing alike. The first is a avea nevoie de — literally "to have need of" — built on the verb a avea you already know: Am nevoie de ajutor ("I need help"). The second is the dative a-i trebui — literally "to-me is-needed" — where, strangely to an English speaker, the thing you need becomes the subject of the sentence: Îmi trebuie timp ("I need time"). Both are everyday, both are correct, and they differ mainly in feel and grammar. On top of these, "I need to do something" is am nevoie să or trebuie să + a clause — never an infinitive. This page sorts out all three patterns, the obligatory little word de, and the agreement surprise in a-i trebui.

a avea nevoie de + noun

The most transparent way to say you need a thing is a avea nevoie de + the noun. A avea conjugates normally for the person (am, ai, are, avem, aveți, au); nevoie ("need") stays fixed; and the noun follows the obligatory preposition de.

Person	Form	Meaning
eu	am nevoie de	I need
tu	ai nevoie de	you need
el / ea	are nevoie de	he / she needs
noi	avem nevoie de	we need
voi	aveți nevoie de	you (pl.) need
ei / ele	au nevoie de	they need

Am nevoie de ajutor cu mutatul mobilei.

I need help moving the furniture.

Ai nevoie de ceva de la magazin?

Do you need anything from the shop?

Copilul are nevoie de mai mult somn.

The child needs more sleep.

The non-negotiable point is the de. Nevoie always reaches its object through de, exactly the way English "in need of" does. Leaving it out — am nevoie ajutor — is the single most common mistake English speakers make here, because English "I need help" has no preposition. (This is part of the wider a avea + noun family of state-expressions covered in uses of a avea.)

💡

Lock in the preposition as part of the phrase: it is not a avea nevoie + a noun, it is a avea nevoie DE + a noun. Memorize it with the de attached — "nevoie-de" — and you'll never drop it.

a avea nevoie să + clause: "need to do"

When you need to do something rather than have something, switch from de + noun to să + a conjugated clause. Am nevoie să dorm = "I need to sleep." The verb after să is conjugated for the same subject as a avea.

Am nevoie să dorm câteva ore, sunt epuizat.

I need to sleep a few hours, I'm exhausted.

Avem nevoie să vorbim despre ce s-a întâmplat.

We need to talk about what happened.

Are nevoie să fie lăsat în pace o vreme.

He needs to be left alone for a while.

The crucial contrast: a noun takes de (am nevoie de odihnă, "I need rest"), an action takes să (am nevoie să mă odihnesc, "I need to rest"). What Romanian never uses here is a bare infinitive — there is no am nevoie a dormi in modern usage. The să-clause is how Romanian builds almost all "need/want/must to do" structures, since the language strongly prefers the conjunctive over the infinitive.

a-i trebui: the dative "need" where the thing is the subject

The second way to say "need" flips the grammar inside out. With a-i trebui, the person is in the dative (a clitic: îmi, îți, îi, ne, vă, le), and the thing needed is the grammatical subject — so the verb trebuie agrees with the thing, not with the person. Îmi trebuie timp is literally "to-me is-needed time," with timp as the subject.

Dative (the person)	Form	Meaning
îmi	îmi trebuie	I need
îți	îți trebuie	you need
îi	îi trebuie	he / she needs
ne	ne trebuie	we need
vă	vă trebuie	you (pl.) need
le	le trebuie	they need

Îmi trebuie doi lei pentru bilet.

I need two lei for the ticket.

Cât timp îți trebuie ca să termini?

How much time do you need to finish?

Ne trebuie o mașină mai mare pentru familie.

We need a bigger car for the family.

Because the thing needed is the subject, trebuie shows up in the plural when that thing is plural — îmi trebuiau bani ("I needed money," where bani is plural and drives the verb into the plural trebuiau). This is the agreement surprise: in a-i trebui, you agree the verb with what is needed, never with the needer.

Îmi trebuiau niște piese pe care nu le mai găseam nicăieri.

I needed some parts that I couldn't find anywhere anymore. (plural 'piese' → plural 'trebuiau')

Le trebuie mai mulți voluntari pentru eveniment.

They need more volunteers for the event.

💡

Think of a-i trebui like English "it takes": Îmi trebuie două ore ≈ "It takes me two hours." The thing (the two hours) is the subject; the person is along for the ride in the dative. That mental model fixes both the word order and the agreement.

The dative trebuie can also take a să-clause for "need to do," overlapping with the modal a trebui: Îmi trebuie să mă odihnesc is heard, though plain trebuie să mă odihnesc ("I need to / have to rest") is far more common. The dative construction's real home is needing a thing. (For the full modal a trebui, including obligation and "should have," see a trebui.)

a avea nevoie de vs a-i trebui: which to pick

Both translate "need" and overlap heavily; the differences are nuance and grammar, not a hard rule.

	a avea nevoie de	a-i trebui
Person is…	the subject (am, ai…)	in the dative (îmi, îți…)
Verb agrees with…	the person	the thing needed
Connector to a noun	de (am nevoie de X)	none (îmi trebuie X)
Feel	broader; abstract or concrete needs, emotional too	often concrete, practical, "what it takes"

In practice, am nevoie de is the safe default that covers everything from am nevoie de tine ("I need you") to am nevoie de o pauză ("I need a break"). Îmi trebuie leans toward concrete, practical requirements — money, time, tools, ingredients — though both are heard for most things.

Am nevoie de tine acum mai mult ca oricând.

I need you now more than ever. (emotional — a avea nevoie de fits naturally)

Îmi trebuie o șurubelniță, ai una?

I need a screwdriver, do you have one? (concrete tool — a-i trebui fits naturally)

Impersonal: e nevoie să

There is also a subjectless version, e nevoie să ("it is necessary to / there's a need to"), which states a need in the abstract, without saying whose need it is. The person, if mentioned at all, can appear in the dative: îmi e nevoie is rare, but e nevoie să... is everyday. This impersonal pattern belongs to the family of constructions that trigger the să-clause, covered in the subjunctive after impersonal expressions.

Nu e nevoie să te grăbești, avem timp destul.

There's no need to hurry, we have plenty of time.

E nevoie de mai multă răbdare cu el.

More patience is needed with him. (impersonal with de + noun)

Note that the impersonal also takes de before a noun (e nevoie de răbdare, "patience is needed"), keeping the same nevoie-de link as the personal form.

Common Mistakes

Dropping the obligatory de after nevoie:

❌ Am nevoie ajutor.

Incorrect — nevoie reaches its object through de: Am nevoie de ajutor.

✅ Am nevoie de ajutor.

I need help.

Using an infinitive for "need to do":

❌ Am nevoie a dormi.

Incorrect — 'need to do' uses a să-clause, not an infinitive: Am nevoie să dorm.

✅ Am nevoie să dorm.

I need to sleep.

Making trebuie agree with the person instead of the thing:

❌ Îmi trebui bani. / Eu trebuie bani.

Incorrect — in a-i trebui the verb agrees with the thing (the subject), and the person is dative: Îmi trebuie bani.

✅ Îmi trebuie bani.

I need money.

Failing to make trebuie plural when the thing needed is plural:

❌ Îmi trebuie două ouă... a, scuze, am vrut: îmi trebuia. (singular with a plural thing in the past)

Incorrect in the past tense — plural 'ouă' drives the verb plural: Îmi trebuiau două ouă.

✅ Îmi trebuiau două ouă pentru rețetă.

I needed two eggs for the recipe.

Adding de to the dative construction (it belongs only to a avea nevoie):

❌ Îmi trebuie de timp.

Incorrect — a-i trebui takes the noun directly, no de: Îmi trebuie timp. (The de belongs to 'am nevoie de timp'.)

✅ Îmi trebuie timp.

I need time.

Key Takeaways

Two ways to say "need": a avea nevoie de
- noun (Am nevoie de ajutor) and the dative a-i trebui (Îmi trebuie timp).
With a avea nevoie, the de is obligatory before a noun; with a-i trebui, the noun follows directly (no de).
In a-i trebui, the thing needed is the subject — trebuie agrees with it, going plural for a plural thing (îmi trebuiau bani); the person is in the dative (îmi, îți, îi…).
"Need to do" is am nevoie să / trebuie să
- a clause — never an infinitive (am nevoie a dormi).
The impersonal e nevoie să ("there's a need to") states need in the abstract, and e nevoie de
- noun keeps the de link.
