Grammar Rule in 30 Seconds

Use the Perfect (Perfect Compus) for completed actions and the Imperfect (Imperfect) for ongoing or habitual actions in the past.

  • Perfect Compus: Use for a single, finished action (e.g., 'Am mâncat' - I ate).
  • Imperfect: Use for ongoing background scenes (e.g., 'Mâncam' - I was eating).
  • Habitual: Use Imperfect for repeated past actions (e.g., 'Mâncam mereu' - I always used to eat).
Perfect: [Am/Ai/A/Am/Ați/Au + Participle] | Imperfect: [Verb stem + -am/-ai/-a/-am/-ați/-au]

Overview

Talking about the past in Romanian is like using a camera. Sometimes you want a high-definition video. Other times you just need a quick polaroid snap.
This is where the choice between Imperfectul and Perfectul Compus comes in. These two tenses are the bread and butter of Romanian conversation. If you want to tell a story, you need both.
One sets the stage while the other provides the action. Think of it like a movie production. The Imperfectul is the background music and the scenery.
The Perfectul Compus is the actor walking onto the stage and saying a line. Yes, even native speakers mix these up when they are tired. But don't worry, you will master this faster than a Romanian grandma makes sarmale.

How This Grammar Works

In Romanian, we focus on how an action happens, not just when. This is called grammatical aspect. Imperfectul is the unfished tense.
It describes actions that were ongoing or repeated in the past. It doesn't really care when the action started or ended. It just knows it was happening.
On the other hand, Perfectul Compus is the completed tense. It describes finished actions that happened at a specific point. It’s like a box that is now closed and taped shut.
You use Imperfectul to say I was eating and Perfectul Compus to say I ate. It’s a simple distinction that makes your Romanian sound incredibly natural. Think of it as a grammar traffic light. Imperfectul is the yellow light (moving, transitioning), and Perfectul Compus is the red light (stopped, finished).

Formation Pattern

1
To form the Imperfectul, take the verb stem and add specific endings. For -a verbs like a lucra, use -am, -ai, -a, -am, -ați, -au. For example, eu lucram means I was working.
2
For -ea, -e, and -i verbs, the endings change slightly but follow a predictable rhythm. You will notice the letter e or i popping up before the ending. For instance, a vedea becomes vedeam.
3
The Perfectul Compus is a team effort. It uses two parts: a helper verb and the past participle.
4
The helper verb is a shortened form of a avea. These are am, ai, a, am, ați, au.
5
The past participle usually ends in -at (for -a verbs) or -ut, -it, -et (for others). For example, a mânca becomes am mâncat.
6
To make it negative, just put nu in front of the whole thing. Nu lucram or nu am lucrat. Easy, right?

When To Use It

Use Imperfectul when you are describing a scene or a habit. If you are talking about your childhood, this is your best friend.
I used to play
is always mă jucam.
It is also perfect for describing the weather or how you were feeling. If you say
The sun was shining,
use soarele strălucea. Use Perfectul Compus for the main events of your day.
If you went to the store, bought milk, and came home, those are all Perfectul Compus. In a job interview, use Perfectul Compus to list your achievements.
I finished the project
is am terminat proiectul.
Use it for anything that has a clear beginning and end. It's the tense for people who like to get things done.

When Not To Use It

Don't use Imperfectul for a one-time event that happened and finished. If you say mâncam un măr when you mean "I ate an apple (and it's gone)," people will wait for you to finish the sentence. They will think you were interrupted.
I was eating an apple... and then what?
Don't use Perfectul Compus for things that define a long period of your life without a specific end. Saying am fost fericit (I was happy) sounds like a very short, specific moment of joy.
If you were generally a happy kid, eram fericit is the way to go. Avoid using Imperfectul for lists of sequential actions. It makes the story feel like it’s stuck in slow motion.

Common Mistakes

Many people try to use the English did for everything. This leads to using Perfectul Compus for habits. If you say am mers la sală în fiecare zi last year, it sounds slightly robotic. Use mergeam instead. Another classic mistake is forgetting the auxiliary verb in Perfectul Compus. You can't just say eu lucrat. You must say eu am lucrat. It’s like trying to drive a car without wheels. Also, watch out for the third person singular in Imperfectul. For a fi, it is era (he/she was). Many learners accidentally use erau, which is plural. Remember: one person era, many people erau. Even the best of us trip over these sometimes, so don't sweat it!

Contrast With Similar Patterns

In English, we have I was working and I worked. Romanian Imperfectul covers both I was working and
I used to work.
This makes it very powerful. In Spanish or French, the rules are very similar to Romanian. If you know those languages, you have a head start!
The biggest contrast is with the Perfectul Simplu. In some parts of Romania (like Oltenia), people use Perfectul Simplu for recent actions. But in standard Romanian, Perfectul Compus is the king of the past.
If you stick to Perfectul Compus for finished actions, you will be understood everywhere from Bucharest to Cluj.
