Coordination and Agreement | Greek Grammar

Coordination joins equal units: noun phrase with noun phrase, predicate with predicate, or clause with clause. The conjunction pages explain και, ή, αλλά, and ούτε; this page focuses on structure, agreement, and omitted material.

Joining like with like

Coordinated units normally perform the same job. Two objects may follow one verb, two predicates share a subject, or two clauses stand side by side.

Η Δανάη αγόρασε μήλα και πορτοκάλια για τα παιδιά.

i Dhanái aghórase míla ke portokália ya ta pedhiá

Danae bought apples and oranges for the children.

Ο Μάνος έκλεισε τον υπολογιστή και κατέβηκε για φαγητό.

o Mános éklise ton ipoloyistí ke katévike ya fayitó

Manos shut down the computer and went downstairs to eat.

Θα έρθω μαζί σας ή θα σας περιμένω εκεί.

tha értho mazí sas i tha sas periméno ekí

I'll come with you, or I'll wait for you there.

In the second example, both predicates share ο Μάνος, so Greek does not repeat it. A coordinator can likewise join adjectives or prepositional phrases in the same slot: ήρεμος αλλά αποφασισμένος, στο σπίτι ή στο γραφείο.

💡

Replace both members with the same question word. If both answer “what?”, “where?”, or “what happened?”, they are structurally parallel.

Agreement with coordinated subjects

Two singular noun phrases joined inclusively by και refer to more than one participant, so the verb is plural.

Ο Στέλιος και η Ράνια δουλεύουν από το σπίτι σήμερα.

o Stélios ke i Ránia dhulévun apó to spíti símera

Stelios and Rania are working from home today.

Different persons resolve through first > second > third: first person includes the speaker; without it, second person includes the addressee.

Ο Γιάννης και εγώ πήγαμε μαζί στην τράπεζα.

o Yánis ke eghó píghame mazí stin trápeza

Yannis and I went to the bank together.

Εσύ και η αδερφή σου θα μείνετε εδώ απόψε.

esí ke i adherfí su tha mínete edhó apópse

You and your sister will stay here tonight.

Thus εγώ + οποιοσδήποτε άλλος → εμείς, while εσύ + τρίτο πρόσωπο → εσείς. With two third-person subjects, use third-person plural. This resolved agreement is the neutral learner default and is required when the coordinated subject comes before the verb.

Postverbal coordinated subjects add a real alternative: the verb may agree only with the first conjunct, although resolved plural agreement remains possible. The following question therefore has two grammatical versions. The singular ήρθες picks up the first member εσύ; plural ήρθατε resolves the whole coordination.

✅ Ήρθες εσύ και η Μαρία;

írthes esí ke i María;

Did you and Maria come? (postverbal first-conjunct agreement)

✅ Ήρθατε εσύ και η Μαρία;

írthate esí ke i María;

Did you and Maria come? (resolved plural agreement)

With ή, the speaker may be asking which single alternative applies, so singular agreement is possible: Ο Πέτρος ή η Νίκη θα οδηγήσει; If the alternatives are understood as a plural set, plural agreement can occur. The intended number, not the printed conjunction alone, decides the form.

Shared material and gapping

Coordination avoids needless repetition. When two parallel clauses contain the same verb, the second may omit it; the remaining constituents show how to reconstruct the missing predicate.

Εγώ παρήγγειλα ψάρι και η Άννα σαλάτα.

eghó paríngila psári ke i Ána saláta

I ordered fish, and Anna salad.

Ο ένας πήρε το λεωφορείο και ο άλλος το μετρό.

o énas píre to leoforío ke o álos to metró

One took the bus and the other the metro.

The absent verb is understood from the first conjunct: η Άννα [παρήγγειλε] σαλάτα, ο άλλος [πήρε] το μετρό. The remnants keep the cases their silent verb would assign. This concise pattern is neutral in conversation and writing; more elaborate gapping is common in (formal) prose. See ellipsis and gapping for the full system.

Correlative rhythm, asyndeton, and polysyndeton

The pairs και…και, ή…ή, ούτε…ούτε make parallel scope explicit. Their meanings belong to coordinating conjunctions; syntactically, each repeated item should introduce the same kind of constituent.

Και η διευθύντρια και οι υπάλληλοι συμφώνησαν με την αλλαγή.

ke i dhiefthíndria ke i ipálili simfónisan me tin alayí

Both the director and the employees agreed with the change.

Greek lists normally use commas between the early members and και before the last, without an English-style compulsory Oxford comma.

Πήρα ψωμί, τυρί, ντομάτες και ελιές.

píra psomí, tirí, domátes ke eliés

I bought bread, cheese, tomatoes, and olives.

Leaving out the final conjunction is asyndeton. It makes a list brisk, compressed, or dramatic and is common in headlines, descriptions, and (literary) prose. Repeating και before every member is polysyndeton; it slows the rhythm and presents the accumulation as emphatic.

Άνοιξε την πόρτα, κοίταξε γύρω, έφυγε χωρίς κουβέντα.

ánikse tin pórta, kítakse yíro, éfiye chorís kuvénda

He opened the door, looked around, and left without a word. (compressed narrative)

Και τηλεφώνησε και έστειλε μήνυμα και περίμενε έξω από το σπίτι.

ke tilefónise ke éstile mínima ke perímene ékso apó to spíti

She called and texted and waited outside the house. (emphatic accumulation)

💡

Asyndeton and polysyndeton are choices of information rhythm, not random punctuation variants. The first accelerates; the second makes the listener count every added event.

Common Mistakes

1. Letting third person override an expressed first-person member.

❌ Εγώ και ο Λουκάς πήγαν στο φαρμακείο.

Incorrect—the coordinated group includes the speaker, so the verb must be first-person plural.

✅ Εγώ και ο Λουκάς πήγαμε στο φαρμακείο.

eghó ke o Lukás píghame sto farmakío

Loukas and I went to the pharmacy.

2. Using singular agreement for a preverbal inclusive subject.

❌ Η Νεφέλη και ο Ορέστης μένει στον Βόλο.

Incorrect—a preverbal coordinated subject requires resolved plural agreement.

✅ Η Νεφέλη και ο Ορέστης μένουν στον Βόλο.

i Neféli ke o Oréstis ménun ston Vólo

Nefeli and Orestis live in Volos.

3. Giving a gapped subject the object's case.

❌ Εγώ παρήγγειλα καφέ και τον Πέτρος τσάι.

Incorrect—the second remnant is the subject of the omitted verb, so both its article and noun must be nominative.

✅ Εγώ παρήγγειλα καφέ και ο Πέτρος τσάι.

eghó paríngila kafé ke o Pétros tsái

I ordered coffee, and Petros ordered tea.

Key Takeaways

Coordinate units that occupy the same syntactic slot.
Preverbal inclusive X και Y subjects take resolved plural agreement with person hierarchy 1 > 2 > 3; a postverbal subject may instead trigger first-conjunct agreement.
A shared verb may disappear from the second conjunct, but its remnants retain their grammatical cases.
Ordinary lists use commas plus final και; asyndeton accelerates, while polysyndeton adds emphatic weight.
