Romanian has two everyday past tenses, and choosing between them is one of the genuine rites of passage in learning the language. The perfect compus (am citit, a plecat) reports a completed, bounded event — something that happened and finished. The imperfect (citeam, pleca) paints an ongoing, habitual, or background situation — something that was unfolding, repeating, or simply true at the time. English collapses both of these into a single past tense most of the time ("I read," "I left"), which is exactly why English speakers default to one form and use it for everything. This page gives you a decision frame, the classic minimal pairs, and — the genuinely hard part — the verbs that switch meaning depending on which past you choose.
The quick answer
Ask one question: is the action a finished whole, or a running scene?
- Finished whole — it started and ended, it advances the story, you could put a "and then" before the next event → perfect compus. Am citit cartea. (I read the book — and finished it.)
- Running scene — it was in progress, repeated, or describes the background → imperfect. Citeam când a sunat telefonul. (I was reading when the phone rang.)
The decision frame
1. Did the action complete as a single, bounded event?
If yes — the deed is done, it has a clear endpoint — use the perfect compus.
Am terminat raportul și l-am trimis șefei.
I finished the report and sent it to my boss.
Ieri am mâncat la restaurantul ăla nou din centru.
Yesterday I ate at that new restaurant downtown.
A plecat la cinci dimineața ca să prindă trenul.
He left at five in the morning to catch the train.
2. Was the action ongoing, repeated, or part of the scenery?
If yes — it was unfolding, it happened habitually, or it sets the background — use the imperfect.
Când eram mic, mergeam la bunici în fiecare vară.
When I was little, I used to go to my grandparents' every summer.
Ploua liniștit și nu era nimeni pe stradă.
It was raining quietly and there was no one in the street.
Lucra de zece ani la aceeași firmă când a venit oferta.
She'd been working at the same company for ten years when the offer came.
3. Two pasts in one sentence: scene + event
The classic combination puts an imperfect background together with a perfect-compus interruption. The imperfect is the scene already in progress; the perfect compus is the thing that cut in.
Citeam în pat când s-a stins lumina.
I was reading in bed when the light went out.
Vorbeam la telefon și deodată a intrat în cameră.
I was on the phone and suddenly he walked into the room.
Tocmai ieșeam pe ușă când a început să plouă.
I was just walking out the door when it started to rain.
A short narrative, mixing both
Read how the two tenses divide labour in a real paragraph. The imperfect verbs (in italics in the gloss) set the scene; the perfect-compus verbs drive the events.
Era deja întuneric și ningea ușor. Mergeam spre casă și mă gândeam la nimic. Deodată am auzit un zgomot, m-am întors și am văzut o pisică pe gard. Am zâmbit și mi-am continuat drumul.
It was already dark and snowing lightly. I was walking home, thinking about nothing. Suddenly I heard a noise, turned around, and saw a cat on the fence. I smiled and went on my way.
Notice the pattern: era, ningea, mergeam, mă gândeam (imperfect — the standing scene), then am auzit, m-am întors, am văzut, am zâmbit, mi-am continuat (perfect compus — the chain of finished events that moves the story).
The genuinely hard part: verbs that change meaning
Here is where the contrast stops being purely about time and becomes lexical. A handful of common verbs mean something different in the perfect compus (where the focus is on the change of state) than in the imperfect (where the focus is on the ongoing state). This is the part you cannot get from a "completed vs ongoing" rule alone — you have to learn each verb.
| Verb | Imperfect (ongoing state) | Perfect compus (change / onset) |
|---|---|---|
| a ști | știam — I knew (already) | am știut — I found out / I knew (at that moment) |
| a vrea | voia — he wanted (was willing) | a vrut — he decided / he tried, made the choice |
| a putea | putea — he was able (had the capacity) | a putut — he managed (and did it) |
| a cunoaște | cunoștea — he knew (was acquainted with) | a cunoscut — he met (for the first time) |
The clearest pair is a ști. Știam is the steady state of already having knowledge; am știut is inchoative — it marks the moment the knowledge arrived, "I found out."
Știam că vine, mi-a spus mama de dimineață.
I knew he was coming — my mom told me this morning. (ongoing knowledge)
Am știut imediat că ceva nu e în regulă.
I knew at once that something was wrong. (the realization hit)
Likewise a vrea: voia is wanting as a continuing state, while a vrut points at the decisive moment — he made up his mind, or he gave it a go.
Voia să devină medic încă din copilărie.
She wanted to become a doctor ever since childhood. (lasting desire)
A vrut să deschidă ușa, dar era încuiată.
He tried to open the door, but it was locked. (a single attempt)
And a cunoaște: cunoșteam means I was acquainted with someone; am cunoscut means I met them, the first encounter.
O cunoșteam de ani de zile, eram colegi de facultate.
I'd known her for years — we were university classmates. (acquaintance)
Am cunoscut-o aseară la petrecerea Anei.
I met her last night at Ana's party. (first meeting)
Comparison with English
English usually has one simple past ("I read," "I knew") and offloads the aspect onto extra words: used to and would for habits, the past progressive was reading for ongoing action. Romanian builds all of that into the single imperfect form. So citeam alone covers English "I was reading," "I used to read," and "I read (habitually)" — three English constructions, one Romanian tense. The trap for English speakers is reaching for the perfect compus by default (because English's simple past looks simple) and thereby flattening every background and habit into a finished event. Train yourself to ask the scene-vs-event question before every past-tense verb.
Common Mistakes
❌ Când am fost mic, am mers la bunici în fiecare vară.
Incorrect — a recurring childhood habit and a background state are imperfect: eram, mergeam.
✅ Când eram mic, mergeam la bunici în fiecare vară.
When I was little, I used to go to my grandparents' every summer.
❌ Citeam cartea și am terminat-o aseară.
Incorrect for a finished, bounded reading — the completion is a perfect-compus event: am citit-o / am terminat-o.
✅ Am citit cartea și am terminat-o aseară.
I read the book and finished it last night.
❌ Ieri ploua toată ziua, așa că am stat în casă.
Acceptable for the background, but if you mean it rained the whole day as a complete fact, use the perfect compus: a plouat.
✅ Ieri a plouat toată ziua, așa că am stat în casă.
Yesterday it rained all day, so I stayed indoors.
❌ Am cunoscut-o de mulți ani.
Incorrect — lasting acquaintance is the imperfect: o cunoșteam. The perfect compus means the moment of first meeting.
✅ O cunoșteam de mulți ani.
I'd known her for many years.
Key Takeaways
- Perfect compus = a completed, bounded event that advances the narrative.
- Imperfect = an ongoing, habitual, or background situation — the running scene.
- The standard combination is imperfect background + perfect-compus interruption: Citeam când a sunat telefonul.
- For a ști, a vrea, a putea, a cunoaște, the choice changes the meaning: imperfect = the state, perfect compus = the onset, decision, success, or first encounter.
- English speakers default to one past for everything — ask "finished whole or running scene?" before each verb.
