Using the Aorist | Greek Grammar

If you want to talk about the past in Greek, the aorist is your workhorse. It is the default past tense — the one you reach for whenever an action happened and finished, as a single, bounded whole. I went, I saw, I ate, I decided. Most of the time it maps neatly onto the English simple past (went, saw, ate), which makes it the friendliest past tense for an English speaker to start with. The subtlety is not in the aorist itself but in knowing when Greek instead wants the imperfect — and this page is about the four everyday jobs the aorist owns outright.

The idea underneath all four is a single one: the aorist views an event from the outside, as a completed package. It does not care how long the event lasted or what it felt like from inside — only that it is done and bounded. Hold on to that picture and every use below follows from it.

1. Single, finished actions

The core case. Something happened once and it is over.

Πήγα στην αγορά και αγόρασα ντομάτες και ψωμί.

pígha stin aghorá ke aghórasa domátes ke psomí

I went to the market and bought tomatoes and bread.

Χθες τελείωσα το βιβλίο που μου χάρισες.

chthes telíosa to vivlío pu mu chárises

Yesterday I finished the book you gave me.

Ξύπνησα στις εφτά και έφυγα αμέσως για τη δουλειά.

ksípnisa stis eftá ke éfigha amésos ya ti dhuliá

I woke up at seven and left for work right away.

2. A sequence of events — the narrative aorist

When you tell a story, each thing that happens next is an aorist. The events line up like beads on a string, one finishing before the next begins. This is the natural engine of narration, and it is where the aorist truly shines: string several together and you have a story.

Μπήκε στο μαγαζί, κάθισε σε μια γωνία και παρήγγειλε έναν καφέ.

bíke sto maghazí, káthise se mia ghonía ke paríngile énan kafé

He came into the shop, sat down in a corner and ordered a coffee.

Χθες γύρισα αργά, έβγαλα τα παπούτσια μου και έπεσα στον καναπέ.

chthes yírisa arghá, évghala ta papútsia mu ke épesa ston kanapé

Yesterday I got back late, took off my shoes and collapsed on the sofa.

💡

Test yourself with the phrase "and then". If your English sentence could carry an "…and then…" between the verbs (came in and then sat down and then ordered), those verbs are almost certainly aorists in Greek. Sequence is the aorist's home turf.

3. Actions with a result or endpoint

Some verbs describe reaching a goal — learning, finding, deciding, building. The aorist frames them as the moment the endpoint was reached, even if the process took years. Έμαθα ελληνικά does not mean "I was learning" — it means the learning arrived at a result: I learned (and now I know).

Έμαθα ελληνικά σε δύο χρόνια, ζώντας στο νησί.

ématha eliniká se dhío chrónia, zóndas sto nisí

I learned Greek in two years, living on the island.

Επιτέλους αποφάσισα να αλλάξω δουλειά.

epitélus apofásisa na alákso dhuliá

I've finally decided to change jobs.

Notice the second translation: English often reaches for the present perfect ("I've decided") where Greek uses a plain aorist. That mismatch is worth flagging early — see the mistakes section below.

4. Time-bounded states and durations

This is the case that trips English speakers up, because the verb feels durative. Μένω ("stay, live") sounds like something that stretches out — and yet έμεινα δύο χρόνια takes the aorist. Why? Because a closed span — two years, from a start to an end — is itself a bounded whole. Greek looks at the whole stretch from the outside, sees its edges, and treats it as one completed package. The clock-time inside is irrelevant; what matters is that the period is closed.

Έμεινα δύο χρόνια στην Κρήτη πριν γυρίσω πίσω στην Αθήνα.

émina dhío chrónia stin Kríti prin yiríso píso stin Athína

I stayed two years in Crete before coming back to Athens.

Περιμέναμε μισή ώρα και μετά φύγαμε.

periméname misí óra ke metá fíghame

We waited half an hour and then we left.

💡

The tell-tale sign is a measured amount of time — δύο χρόνια, μισή ώρα, τρεις μέρες — with a clear start and end. A bounded quantity of time makes even a "stretchy" verb (μένω, περιμένω, δουλεύω) go aorist. Contrast an open background stretch with no edges, which stays imperfective.

Where the imperfect takes over

The aorist's opposite number is the imperfect, which handles the background: what was going on, what used to happen, what set the scene. In real speech the two work together — the imperfect paints the backdrop, the aorists move the plot forward. Look how they share the labour in one breath:

Έξω έβρεχε, οπότε άναψα τη θέρμανση και έφτιαξα έναν ζεστό καφέ.

ékso évreche, opóte ánapsa ti thérmansi ke éftiaksa énan zestó kafé

It was raining outside, so I turned on the heating and made a hot coffee.

Here έβρεχε ("was raining") is the ongoing backdrop — imperfect — while άναψα and έφτιαξα are the two finished moves — aorists. The same contrast decides between a one-off and a habit:

Χθες έβρεξε το απόγευμα και δρόσισε ο καιρός.

chthes évrekse to apóyevma ke dhrósise o kerós

Yesterday it rained in the afternoon and the weather cooled down.

Εκείνο το καλοκαίρι έβρεχε σχεδόν κάθε απόγευμα.

ekíno to kalokéri évreche schedhón káthe apóyevma

That summer it rained almost every afternoon.

The first is a single bounded shower (έβρεξε, aorist); the second is a repeated, habitual backdrop (έβρεχε, imperfect). Drawing that line consistently is the whole skill — the imperfect vs aorist page is the decision guide, and aspect in the past explains the underlying logic.

Common Mistakes

1. Using the imperfect for a single completed trip or event. πήγαινα means was going / used to go; a one-off, finished journey is πήγα.

❌ Πέρσι πήγαινα στην Ιταλία για δέκα μέρες.

Incorrect — a single completed trip is the aorist: πήγα.

✅ Πέρσι πήγα στην Ιταλία για δέκα μέρες.

pérsi pígha stin Italía ya dhéka méres

Last year I went to Italy for ten days.

2. Using the aorist for a habit. A repeated, "every summer" action is background — that is the imperfect.

❌ Κάθε καλοκαίρι πήγα στο χωριό της γιαγιάς μου.

Incorrect — a repeated habit needs the imperfect: πήγαινα.

✅ Κάθε καλοκαίρι πήγαινα στο χωριό της γιαγιάς μου.

káthe kalokéri píyena sto chorió tis yayás mu

Every summer I used to go to my grandmother's village.

3. Copying the English present perfect with έχω. With a specific past time (πριν μία ώρα, χθες), Greek uses the plain aorist, not a "have + verb" construction.

❌ Έχω φάει πριν μία ώρα, δεν πεινάω.

Incorrect — with a stated past time, Greek uses the aorist: έφαγα.

✅ Έφαγα πριν μία ώρα, δεν πεινάω.

éfagha prin mía óra, dhen pináo

I ate an hour ago, I'm not hungry.

4. Using the imperfect for a closed span of time. A measured, finished duration is bounded, so it is the aorist.

❌ Έμενα πέντε χρόνια στο Λονδίνο και μετά γύρισα.

Incorrect — a closed, bounded span takes the aorist: έμεινα.

✅ Έμεινα πέντε χρόνια στο Λονδίνο και μετά γύρισα.

émina pénde chrónia sto Londhíno ke metá yírisa

I lived five years in London and then I came back.

Key Takeaways

The aorist is the default past for anything finished and bounded, and it usually matches the English simple past.
Four everyday jobs: single finished actions (πήγα), chained narrative events (μπήκε, κάθισε, παρήγγειλε), actions with a result (έμαθα, αποφάσισα), and closed spans of time (έμεινα δύο χρόνια).
A measured duration makes even a durative verb go aorist — the span has edges, so Greek sees it as one whole.
The imperfect owns the background and the habit; the two tenses collaborate — imperfect sets the scene, aorists move it along.
Watch the English present perfect: "I've already eaten (an hour ago)" is a Greek aorist, έφαγα, not an έχω-construction.
To say you didn't do it, nothing changes but the little word in front: δεν
- the same aorist, no auxiliary — see negating the past.
