Most Greek agreement follows visible grammatical features: a singular subject selects a singular verb, and an adjective matches gender, number, and case. At the edges of the system, however, speakers may also respond to meaning—a singular collective contains many people, polite εσείς refers to one person, and two singular nouns denote a plural set. These are structured resolutions, not random exceptions.
Form agreement and semantic agreement
With a collective noun, grammatical form and real-world number diverge. Ο κόσμος is masculine singular even when it means “people,” so singular agreement is the neutral and formal default.
Ο κόσμος περίμενε υπομονετικά έξω από το θέατρο.
o kózmos perímene ipomonetiká ékso apó to théatro
People waited patiently outside the theater. (neutral/formal agreement)
Η ομάδα αποφάσισε να αλλάξει προπονητή.
i omádha apofásise na aláksi proponití
The team decided to change coach. (neutral agreement)
The verb matches the single grammatical unit ο κόσμος / η ομάδα. This is the reliable choice in edited writing and whenever no individual members are being highlighted. The basic pattern is introduced on subject–verb agreement.
Spontaneous speech can instead “unpack” a human collective and continue with the individuals it contains. Plural agreement with ο κόσμος is licensed in colloquial discourse, especially when the following predicate describes separate actions by members.
Ο κόσμος άρχισαν να φεύγουν μόλις τελείωσε η συναυλία.
o kózmos árchisan na févghun mólis telíose i sinavlía
People started leaving as soon as the concert ended. (colloquial semantic agreement)
Ο κόσμος άρχισε να φεύγει μόλις τελείωσε η συναυλία.
o kózmos árchise na févyi mólis telíose i sinavlía
People started leaving as soon as the concert ended. (neutral/formal grammatical agreement)
Both versions have a grammatical reading. The plural is not a learner default and may look unsuitable in formal prose; it is nevertheless real Greek, not a defective form. English creates the opposite temptation because people is grammatically plural and British English freely says the team are.
Polite εσείς: plural verb, singular predicate
Greek uses second-person plural εσείς to address one person politely. The verb remains morphologically plural, but a predicate adjective or noun can agree semantically with the one addressee.
Κύριε Παπαδάκη, είστε έτοιμος;
kírie Papadháki, íste étimos;
Mr Papadakis, are you ready? (polite singular address)
Κυρία Λάμπρου, είστε η καινούρια διευθύντρια;
kiría Lámbru, íste i kenúria dhiefthíndria;
Ms Lamprou, are you the new director? (polite singular address)
είστε agrees grammatically with polite plural person, while έτοιμος and η καινούρια διευθύντρια describe the singular referent. Gender follows that referent. If εσείς genuinely addresses several people, predicates are plural too.
Κυρίες και κύριοι, είστε έτοιμοι να ξεκινήσουμε;
kiríes ke kíri, íste étimi na ksekinísume;
Ladies and gentlemen, are you ready for us to begin? (true plural address)
English you hides this tension because it has one verb form for singular and plural. In Greek, politeness changes the verb's person-number form without turning one addressee into a grammatically plural predicate referent.
Coordinated singulars resolve as plural
Two singular noun phrases joined by και normally form one plural subject. When they precede the verb, resolved plural agreement is the standard pattern.
Η βροχή και ο δυνατός αέρας σταμάτησαν πριν από λίγο.
i vrochí ke o dhinatós aéras stamátisan prin apó lígho
The rain and the strong wind stopped a short while ago.
Person resolves by the hierarchy first > second > third: a group containing the speaker selects first-person plural; otherwise a group containing the addressee selects second-person plural.
Η Μαρία κι εγώ θα παρουσιάσουμε τα αποτελέσματα.
i María ki eghó tha parusiásume ta apotelézmata
Maria and I will present the results.
Εσύ και ο Στέφανος μπορείτε να περιμένετε εδώ.
esí ke o Stéfanos boríte na periménete edhó
You and Stefanos can wait here.
Postverbal coordination has an additional genuine option: the verb may agree with the first conjunct, although resolved plural agreement remains possible.
Ήρθε η Μαρία και ο Στέφανος;
írthe i María ke o Stéfanos;
Did Maria and Stefanos come? (postverbal first-conjunct agreement)
Ήρθαν η Μαρία και ο Στέφανος;
írthan i María ke o Stéfanos;
Did Maria and Stefanos come? (resolved plural agreement)
This positional alternative is why a blanket rule that every coordinated subject must trigger plural agreement is too strong. The dependable distinction is: preverbal coordination resolves; postverbal coordination may also show first-conjunct agreement.
Gender resolution in mixed groups
For a human group containing both masculine and feminine referents, the conventional resolved form is masculine plural. This affects predicate adjectives, participles, articles, and plural nouns used for the whole group.
Ο Γιάννης και η Μαρία είναι κουρασμένοι από το ταξίδι.
o Yánis ke i María íne kurazméni apó to taksídhi
Yannis and Maria are tired from the trip.
Οι φοιτητές του τμήματος συναντήθηκαν στην αίθουσα.
i fitités tu tmímatos sinandíthikan stin éthusa
The department's students met in the hall. (a mixed or all-male group)
An all-female group takes feminine plural οι φοιτήτριες, κουρασμένες. The masculine plural is the traditional unmarked resolution for a mixed group; where inclusive visibility matters, contemporary formal writing often names both groups explicitly instead of relying on the generic masculine.
Οι φοιτήτριες και οι φοιτητές υπέγραψαν την ανακοίνωση.
i fitítries ke i fitités ipéghrapsan tin anakínosi
The female and male students signed the announcement. (explicit inclusive wording)
Common Mistakes
1. Letting third person override an expressed first-person member.
❌ Ο Αντρέας κι εγώ έστειλαν το αίτημα χθες.
Incorrect—the coordinated subject includes the speaker and requires first-person plural.
✅ Ο Αντρέας κι εγώ στείλαμε το αίτημα χθες.
o Andhréas ki eghó stílame to étima chthes
Andreas and I sent the request yesterday.
2. Using feminine plural for a mixed masculine–feminine pair.
❌ Ο Πέτρος και η Άννα είναι ευχαριστημένες με το αποτέλεσμα.
Incorrect in standard resolution—a mixed pair takes masculine plural ευχαριστημένοι.
✅ Ο Πέτρος και η Άννα είναι ευχαριστημένοι με το αποτέλεσμα.
o Pétros ke i Ána íne efcharistiméni me to apotélezma
Petros and Anna are pleased with the result.
3. Using singular agreement with a preverbal coordinated subject.
❌ Η ζέστη και η υγρασία έγινε αφόρητη.
Incorrect—the preverbal coordination requires plural agreement in both verb and predicate.
✅ Η ζέστη και η υγρασία έγιναν αφόρητες.
i zésti ke i ighrasía éyinan afórites
The heat and humidity became unbearable.
Key Takeaways
- Singular agreement is neutral with collectives; colloquial semantic plural agreement is licensed when members are salient.
- Polite εσείς selects a plural verb but may take a singular predicate describing one addressee.
- Preverbal coordinated subjects resolve in plural and follow person hierarchy 1 > 2 > 3.
- Postverbal coordination additionally allows agreement with its first conjunct.
- Mixed human groups conventionally resolve to masculine plural; explicit paired wording can make genders visible.
