Modal Constructions in Romanian

Overview

Modal constructions let you express what you can do, want to do, or must do — three of the most essential ideas in any language. In Romanian, these concepts revolve around three key verbs: a putea (can, to be able to), a vrea (to want), and a trebui (must, to have to). Mastering them at the A1 level gives you the ability to talk about your wishes, capabilities, and obligations from the very first days of learning.

What makes Romanian modals distinctive is the way they connect to the main verb. Unlike English, where modals are followed by a bare infinitive ("I can swim"), Romanian modals are typically followed by să plus a verb in the subjunctive. This să + subjunctive pattern is one of the defining features of Romanian grammar and will appear again and again as you progress. The good news is that at this stage, the subjunctive forms are mostly identical to the present indicative, so the learning curve is gentle.

One important structural note: a trebui (must) behaves differently from the other two. It is impersonal — it does not conjugate for each person in everyday speech. Instead, you use the fixed form trebuie followed by să + subjunctive, and the person is expressed by the subjunctive verb that follows.

How It Works

A Putea (Can / To Be Able To)

Person	Form
eu	pot
tu	poți
el/ea	poate
noi	putem
voi	puteți
ei/ele	pot

A putea is followed by să + subjunctive:

• Pot să merg. — I can go.
• Poți să vorbești mai încet? — Can you speak more quietly?

A Vrea (To Want)

Person	Form
eu	vreau
tu	vrei
el/ea	vrea
noi	vrem
voi	vreți
ei/ele	vor

A vrea is followed by să + subjunctive:

• Vreau să învăț româna. — I want to learn Romanian.
• Vrei să mergi cu mine? — Do you want to come with me?

A Trebui (Must / To Have To)

Trebuie is impersonal and does not change form. The subject is expressed by the verb after să:

Meaning	Construction
I must	trebuie să + 1st sg. verb
you must	trebuie să + 2nd sg. verb
he/she must	trebuie să + 3rd sg. verb
we must	trebuie să + 1st pl. verb
you (pl.) must	trebuie să + 2nd pl. verb
they must	trebuie să + 3rd pl. verb

• Trebuie să plec. — I must leave.
• Trebuie să mâncăm. — We must eat.

Negation

Place nu before the modal verb:

• Nu pot să dorm. — I can't sleep.
• Nu vrea să vină. — He/She doesn't want to come.
• Nu trebuie să plătești. — You don't have to pay.

Common Mistakes

Using the infinitive instead of să + subjunctive

• Wrong: Vreau a merge.
• Right: Vreau să merg.
• Why: Modern Romanian strongly prefers să + subjunctive over the long infinitive after modal verbs. The infinitive construction sounds archaic.

Conjugating trebuie for each person

• Wrong: Eu trebuiesc să plec.
• Right: Trebuie să plec.
• Why: Trebuie is impersonal — it stays the same regardless of who "must" do the action. The person is shown by the verb after să.

Forgetting să between the modal and the main verb

• Wrong: Pot merg.
• Right: Pot să merg.
• Why: The particle să is required to link the modal verb to the following subjunctive verb.

Confusing nu trebuie with nu-i voie

• Wrong: Nu trebuie să intri! (meaning "you are forbidden to enter")
• Right: Nu ai voie să intri! (forbidden) vs. Nu trebuie să intri. (you don't have to enter)
• Why: Nu trebuie means "it's not necessary," not "it's forbidden." For prohibition, use nu ai voie or nu e permis.

Usage Notes

In spoken Romanian, a putea sometimes appears in a shorter construction: Pot merge (without să), especially in rapid speech. However, the full să construction is standard and always correct at this level.

A vrea has an alternative conditional form aș vrea (I would like), which sounds more polite than the direct vreau. You will encounter this at the A2 level, but it is useful to recognize it in restaurants and shops: Aș vrea o cafea, vă rog (I would like a coffee, please).

Practice Tips

• Build sentences in threes: For each new verb you learn, make three sentences — one with pot, one with vreau, and one with trebuie. For example, with a citi (to read): Pot să citesc. Vreau să citesc. Trebuie să citesc.
• Practice negation early: The pattern nu + modal + să + verb is extremely common. Drill it with everyday verbs until it becomes automatic.
• Use modals for daily narration: Describe your day using modals: Trebuie să mă trezesc la 7. Vreau să beau cafea. Pot să iau autobuzul.
