When you start a language, the instinct is to learn verbs in tidy groups — all the regular -a verbs first, say, because they're "easy". For Romanian, that instinct wastes your early effort. The twenty or so verbs you'll actually use in nearly every sentence are mostly irregular, and they do double and triple duty as auxiliaries (helping build other tenses) and light verbs (carrying meaning in fixed expressions). Learn these first, even though their paradigms are bumpy, and you unlock the machinery of the whole language. Drill regular verbs first and you'll be able to conjugate words you rarely say while stumbling over a fi and a avea, which appear in almost everything.
Why frequency beats regularity
There's a well-known cross-linguistic pattern: the most frequent verbs are the most irregular. High usage shields irregularity from being smoothed out — speakers say am, ai, are so often that there's no pressure to regularize them. Romanian is no exception. So the verbs you most need are precisely the ones with unpredictable forms, which means there's no shortcut: you memorize their paradigms directly, the way you memorize the alphabet. The payoff is enormous, because these same verbs are the gears the rest of the system turns on.
The starter list (in rough priority order)
| Verb | Meaning | Why it's a priority |
|---|---|---|
| a fi | to be | copula + passive auxiliary; highly irregular |
| a avea | to have | past-tense auxiliary (am, ai, a...); irregular |
| a face | to do, to make | light verb in hundreds of expressions |
| a vrea | to want | modal-like; its forms feed the voi-future |
| a putea | to be able to, can | core modal; "can/may" |
| a da | to give | light verb (a da un telefon = to make a call) |
| a merge | to go, to walk; to work (of things) | everyday motion + "it works" |
| a veni | to come | everyday motion |
| a spune / a zice | to say, to tell | reporting speech; both very common |
| a ști | to know (facts) | irregular; "know how to" + infinitive |
| a vedea | to see | perception; "we'll see" (om vedea) |
| a lua | to take | irregular; "take/have" food, transport |
| a sta | to stay, to sit, to live (somewhere) | irregular; location + duration |
| a trebui | must, to have to, to need | impersonal modal; "trebuie să..." |
| a ajunge | to arrive, to reach; to be enough | arrival + "that's enough" |
| a găsi | to find | everyday transitive |
| a pune | to put | everyday transitive; many expressions |
| a crede | to believe, to think (opinion) | "I think that..." (cred că) |
| a lăsa | to leave (sth), to let, to allow | "let me", "leave it" |
Notice how many of these are not simple content verbs. A avea is the past-tense auxiliary; a fi is the copula and passive auxiliary; a vrea contributes the voi-future; a face, a da, a lua, and a pune are light verbs that drain into countless fixed phrases. Learning them is learning grammar, not just vocabulary.
The two auxiliaries you cannot skip: a fi and a avea
These two carry more grammatical weight than any others, so even though they're irregular, learn them on day one.
| Person | a fi (to be) | a avea (to have) |
|---|---|---|
| eu | sunt | am |
| tu | ești | ai |
| el / ea | este / e | are |
| noi | suntem | avem |
| voi | sunteți | aveți |
| ei / ele | sunt | au |
Sunt obosit, am muncit toată ziua.
I'm tired, I worked all day. (a fi as copula, a avea hidden in 'am muncit')
Ai timp mâine? Am o întrebare.
Do you have time tomorrow? I have a question.
The forms am, ai, a, am, ați, au aren't just "to have" — they're the auxiliary of the perfect compus (am mâncat, "I ate"). So learning a avea gives you the entire everyday past tense as a bonus.
The light verbs: a face, a da, a lua, a pune
A light verb carries little meaning on its own but combines with a noun to form a common expression. English does this too ("make a decision", "take a shower"), but Romanian leans on it heavily, and which light verb pairs with which noun is something you learn phrase by phrase.
Fac un duș și vin imediat.
I'll take a shower and come right away. (a face un duș, not a lua)
Trebuie să dau un telefon repede.
I have to make a quick call. (a da un telefon = to make a call)
Iau autobuzul de obicei, e mai ieftin.
I usually take the bus, it's cheaper. (a lua = to take transport)
Pune-ți o haină, e frig afară.
Put a coat on, it's cold outside. (a pune)
Note the cross-language trap: Romanian says a face un duș ("make a shower"), whereas English "takes" one. The light-verb pairings rarely map one-to-one, so memorize the collocation, not a word-for-word translation.
The modals: a putea, a vrea, a trebui, a ști
Modals let you say "I can / want / must / know how to" — and in Romanian they almost always feed into a să-clause (the conjunctiv), which is why learning them early also drills the să habit.
Pot să te ajut cu ceva?
Can I help you with something? (a putea + să)
Vreau să învăț românește bine.
I want to learn Romanian well. (a vrea + să)
Trebuie să plec acum, am întârziat.
I have to go now, I'm late. (a trebui — impersonal, always 'trebuie')
Știu să gătesc, dar nu prea am timp.
I know how to cook, but I don't really have time. (a ști + să)
A trebui deserves a flag: it's impersonal, so for "I/you/he must" the verb stays trebuie and the person shows up in the să-clause (trebuie să plec, trebuie să pleci, trebuie să plece). Don't try to conjugate trebuie for person in the present.
A learning-order rationale
Here's a defensible sequence for the first weeks, designed so each step reuses the previous one:
- a fi, a avea — copula and the past-tense auxiliary. These unlock "to be", "to have", and the entire perfect compus.
- a vrea, a putea, a trebui, a ști — the modals, which also force you to practice the să-clause.
- a merge, a veni, a sta, a lua — everyday motion and "take", the verbs of getting around.
- a face, a da, a pune — the light verbs that fill out daily expressions.
- a spune/a zice, a vedea, a crede, a găsi, a ajunge, a lăsa — reporting, perception, opinion, and the rest of the high-frequency core.
By the time you've cycled through these, you can already say where you are, what you have, what you want, what you can and must do, how you get around, and report what others say — the structural backbone of conversation. Only then does it pay to grind through the large regular classes for verbs like a lucra (to work) or a vorbi (to speak), which are easy precisely because they follow predictable patterns.
Common Mistakes
❌ Eu sunt avut o întrebare.
Incorrect — the past auxiliary is a avea, not a fi: 'am avut', and here you'd just say 'am o întrebare' for the present.
✅ Am o întrebare.
I have a question.
❌ Iau un duș.
Incorrect collocation — Romanian uses a face for a shower, not a lua.
✅ Fac un duș.
I take a shower.
❌ Eu trebui să plec.
Incorrect — a trebui is impersonal; the form is 'trebuie' for every person.
✅ Trebuie să plec.
I have to go.
❌ Vreau învăț românește.
Incorrect — a vrea takes a să-clause: 'vreau să învăț'.
✅ Vreau să învăț românește.
I want to learn Romanian.
❌ (early study) Drilling a se plimba, a colora, a desena before a fi and a avea.
Misprioritized — rare regular verbs before the irregular high-frequency core slows you down.
✅ Learn a fi, a avea, a vrea, a putea, a merge first.
The high-frequency irregulars unlock the most speech per paradigm.
Key Takeaways
- The highest-frequency Romanian verbs (a fi, a avea, a face, a vrea, a putea, a da, a merge, a veni, a ști, a lua) are mostly irregular — frequency shields irregularity.
- Several double as auxiliaries (a avea → the perfect; a vrea/voi → a future; a fi → copula and passive) and light verbs (a face, a da, a lua, a pune).
- Learn a fi and a avea on day one — they unlock the copula and the entire everyday past tense.
- The modals (a putea, a vrea, a trebui, a ști) double as practice for the să-clause; a trebui is impersonal (always trebuie).
- Prioritize this short irregular core over rare regular verbs — it returns far more usable speech per paradigm memorized.
