Accent in the Aorist | Greek Grammar

The aorist has a single, reliable stress habit, and once you name it the whole tense stops feeling like a moving target. The aorist stress is recessive: it falls as far back as Greek permits. In practice that means the antepenult — the third-from-last syllable — wherever the word is long enough to reach it, and the augment exists precisely to make short words long enough. This page makes that rule concrete for both conjugations. For the augment's own logic see the augment in the aorist; for the wider system, verb accentuation and Greek stress rules.

The law behind it: stress can go back three syllables

Modern Greek obeys a hard ceiling often called the three-syllable rule (the law of limitation): the stress can fall no further back than the third-from-last syllable of a word. "Recessive" stress means the accent is pushed as far back as this law allows — and the past tense is the clearest case of recessive stress in the language.

For a word of three or more syllables, "as far back as allowed" is the antepenult. So the aorist of a short Class Α verb comes out proparoxytone — stressed on the antepenult:

έγραψα → έ-γρα-ψα, stress on the first of three syllables, the antepenult.
έτρεξα → έ-τρε-ξα, antepenult again.

Έγραψα το γράμμα στα γρήγορα και το έστειλα αμέσως.

éghrapsa to ghráma sta ghríghora ke to éstila amésos

I wrote the letter quickly and sent it right away.

Έτρεξα όσο πιο γρήγορα μπορούσα, αλλά δεν πρόλαβα.

étreksa óso pio ghríghora borúsa, alá dhen prólava

I ran as fast as I could, but I didn't make it in time.

This is why short verbs need the augment

Now the augment's job clicks into place. Take the perfective stem γραψ- and the 1sg ending -α: the bare form would be γράψα, only two syllables (γρά-ψα). Two syllables cannot host an antepenultimate stress — there is no third syllable to put it on. So Greek supplies one with the augment έ-, and the recessive stress lands on it: έγραψα.

That is the entire reason the augment appears where it does. It is not decoration and it is not a tense marker; it is scaffolding that gives the recessive stress a syllable to stand on. Where the word is already long enough, no scaffolding is added — and the stress still lands on the antepenult.

Person	Form	Syllables	Stressed syllable
εγώ	έγραψα	έ-γρα-ψα	antepenult (έ)
εσύ	έγραψες	έ-γρα-ψες	antepenult (έ)
αυτός	έγραψε	έ-γρα-ψε	antepenult (έ)
εμείς	γράψαμε	γρά-ψα-με	antepenult (γρά)
εσείς	γράψατε	γρά-ψα-τε	antepenult (γρά)
αυτοί	έγραψαν	έ-γρα-ψαν	antepenult (έ)

Read the "stressed syllable" column top to bottom: it says antepenult every single time. The accent never actually moves relative to the end of the word — it sits on the third-from-last syllable throughout. What changes is only which physical syllable that is: in the augmented singular it is the έ-; in γράψαμε, where the ending has supplied its own third syllable, it is γρά-. So the whole paradigm is proparoxytone, and the augment simply comes and goes to keep it that way.

Γράψαμε μαζί το τραγούδι μέσα σε ένα απόγευμα.

ghrápsame mazí to traghúdhi mésa se éna apóyevma

We wrote the song together in one afternoon.

Τρέξαμε στη βροχή μέχρι το αυτοκίνητο και βραχήκαμε.

tréksame sti vrochí méchri to aftokínito ke vrachíkame

We ran in the rain to the car and got soaked.

💡

Don't think of the aorist stress as "jumping" between the singular and the plural. It sits on the antepenult the whole time; the augment only appears in the short forms so that there is an antepenult to land on.

Class Β: the antepenult tracks the lengthening word

Class Β verbs (the -άω/-ώ conjugation) make the pattern even clearer, because they are long enough to need no augment at all — so you can watch the stress track the antepenult with nothing else in the way. Take αγαπώ "love", perfective stem αγαπησ-:

αγάπησα "I loved" → α-γά-πη-σα. Four syllables; antepenult = γά.
αγαπήσαμε "we loved" → α-γα-πή-σα-με. Five syllables; antepenult = πή.

The accent looks like it has slid one syllable to the right — from γά to πή — but it has not left the antepenult for a moment. The word simply grew by one syllable in the plural, so the third-from-last syllable is now a different one. Same law, same recessive stress.

Αγάπησα αυτό το σπίτι με την πρώτη ματιά.

aghápisa aftó to spíti me tin próti matiá

I loved this house at first sight.

Αγαπήσαμε αμέσως τη γειτονιά μας και μείναμε δέκα χρόνια.

aghapísame amésos ti yitoniá mas ke míname dhéka chrónia

We immediately loved our neighbourhood and stayed ten years.

Μιλήσαμε πολλή ώρα, αλλά δεν λύσαμε το πρόβλημα.

milísame polí óra, alá dhen lísame to próvlima

We talked for a long time, but we didn't solve the problem.

When the word is only two syllables

There is one honest limit to state plainly. A handful of aorists come out just two syllables long even after everything is fused — the suppletive pasts like είδα "I saw", ήρθα "I came", ήπια "I drank", μπήκα "I went in". Two syllables cannot be proparoxytone; there is no third syllable to reach. So these land on the first syllable — εί-δα, ήρ-θα — which is still "as far back as the word allows." The rule has not changed; the word has simply run out of room. This is exactly why recessive stress is best stated as "as far back as the three-syllable law permits," not flatly as "always the antepenult." The suppletive aorists themselves are on irregular and suppletive aorists.

Τον είδα χθες στην αγορά, αλλά δεν με πρόσεξε.

ton ídha chthes stin aghorá, alá dhen me prósekse

I saw him yesterday at the market, but he didn't notice me.

Ήρθα με τα πόδια γιατί δεν είχε λεωφορείο τέτοια ώρα.

írtha me ta pódhia yatí dhen íche leoforío tétia óra

I came on foot because there was no bus at that hour.

Common Mistakes

1. Keeping the augment (and its stress) in the 1st/2nd plural. In γράψαμε the ending already supplies the antepenult, so ×έγραψαμε would stress the fourth-from-last syllable — impossible in Greek.

❌ Έγραψαμε ένα γράμμα στον δήμαρχο.

Incorrect — the 1pl drops the augment and stays antepenult: γράψαμε.

✅ Γράψαμε ένα γράμμα στον δήμαρχο.

ghrápsame éna ghráma ston dhímarcho

We wrote a letter to the mayor.

2. Not letting the stress track the antepenult in the Class Β plural. As αγάπησα becomes αγαπήσαμε, the stress must move to the new third-from-last syllable.

❌ Αγάπησαμε πολύ εκείνη τη χρονιά.

Incorrect — the longer plural is proparoxytone on -πή-: αγαπήσαμε.

✅ Αγαπήσαμε πολύ εκείνη τη χρονιά.

aghapísame polí ekíni ti chroniá

We loved that year very much.

3. Stressing the aorist singular like the present. The present αγαπώ is end-stressed; the aorist 1sg is not — it retracts to the antepenult, αγάπησα.

❌ Αγαπήσα τη μουσική από μικρός.

Incorrect — the aorist 1sg is proparoxytone: αγάπησα.

✅ Αγάπησα τη μουσική από μικρός.

aghápisa ti musikí apó mikrós

I've loved music since I was a child.

4. Dropping the augment and leaving the singular with nowhere to stress. A two-syllable form needs the ε- to become proparoxytone.

❌ Τρεξα στο σπίτι μόλις άκουσα τον θόρυβο.

Incorrect — the short singular needs the augment: έτρεξα.

✅ Έτρεξα στο σπίτι μόλις άκουσα τον θόρυβο.

étreksa sto spíti mólis ákusa ton thórivo

I ran home as soon as I heard the noise.

Key Takeaways

Aorist stress is recessive: it falls as far back as the three-syllable law allows.
For forms of three or more syllables that means the antepenult, so the whole paradigm is proparoxytone — έγραψα, γράψαμε, αγάπησα, αγαπήσαμε all stress the third-from-last syllable.
The stress does not "jump"; it stays on the antepenult while the augment appears in short forms and vanishes in longer ones to keep that syllable available.
In Class Β the stressed syllable shifts rightward (αγάπησα → αγαπήσαμε) only because the word gets longer — it is still the antepenult.
Two-syllable suppletive aorists (είδα, ήρθα) stress the first syllable, because that is as far back as the word can go.
