The past tense (am, ai, a)

The Compound Perfect

To talk about the past in Romanian, you use the perfect compus (compound perfect). Similar to English (e.g., "I have eaten"), it combines an auxiliary verb with a past participle. This lesson focuses on these auxiliary verbs—short forms derived from a avea (to have)—alongside high-frequency past participles like fost (been) and făcut (done).

The Auxiliary Forms

Here is the past tense auxiliary. Notice that the forms for "I" and "we" are identical (am).

PronounAuxiliary
Eu (I)am
Tu (You)ai
El / Ea (He / She)a
Noi (We)am
Voi (You all)ați
Ei / Ele (They)au

Helpful Time Words

When talking about the past, you will frequently use words indicating when the event happened. Let's look at two common ones before we build sentences:

yesterday
ieri
last night
aseară

First Person: I and We (am)

The auxiliary for both "I" and "we" is am. Context usually tells you whether the speaker means just themselves or a group.

Yesterday I was at the office.
Ieri am fost la birou.
Last night we partied together.
Aseară am petrecut împreună.

Second Person: You (ai, ați)

Use ai for an informal singular "you", and ați for a plural or formal "you".

What did you do yesterday?
Ce ai făcut ieri?
Did you notice the mistake?
Ați observat greșeala?

Third Person: He, She, It, and They (a, au)

Use a for singular subjects (he, she, or it) and au for plural subjects (they).

The party was wonderful.
Petrecerea a fost minunată.
They did an excellent project.
Au făcut un proiect excelent.

Contrasting Subjects

When multiple people do different things, you can see how the auxiliary shifts to match each subject. The past participle (the main action word) stays the same for that verb, no matter who is doing it.

I worked, and you slept.
Eu am lucrat, iar tu ai dormit.
I read, and they partied.
Eu am citit, iar ei au petrecut.
