English never says "the John". Greek almost always says ο Γιάννης. This page is about that difference and nothing else — whether the article appears, not how the name itself declines. For the endings of Γιάννης, Κώστας, Μαρία, Παπαδόπουλος and the rest, go to declining Greek names and surnames; everything below assumes you can already form the case and asks only where the little word in front goes.
The default: names take the article
Whenever you talk about a person by name, the name carries the definite article, in whatever case the sentence requires.
Ο Γιάννης δουλεύει σε ναυτιλιακή εταιρεία στον Πειραιά.
o Yánis dhulévi se naftiliakí etería ston Pireá
Giannis works for a shipping company in Piraeus.
Είδα τον Γιώργο χθες στο γήπεδο, μου είπε τα νέα.
ídha ton Yórgho chthes sto yípedho, mu ípe ta néa
I saw Giorgos at the stadium yesterday — he told me the news.
Ρώτησε την Άννα, αυτή ξέρει καλύτερα από μένα.
rótise tin Ána, aftí kséri kalítera apó ména
Ask Anna — she knows better than I do.
There is no politeness dimension here and no extra emphasis. Ο Γιάννης is exactly as neutral as English John. Leaving the article out does not sound casual or intimate; it sounds broken.
What the article buys you: case marking
The article is not decorative. It is the piece of the phrase that shows what the name is doing in the sentence — and that matters far more for names than for common nouns, because Greek word order is free and names are the participants you are most likely to reorder.
Ο Πέτρος φώναξε τον Αντρέα από το μπαλκόνι.
o Pétros fónakse ton Andréa apó to balkóni
Petros called out to Andreas from the balcony.
Τον Πέτρο τον φώναξε ο Αντρέας, όχι το αντίθετο.
ton Pétro ton fónakse o Andréas, óchi to andítheto
It was Andreas who called Petros, not the other way round.
Same two people, opposite meanings, and the only thing that tells you which is which is ο versus τον. English has to keep Petros called Andreas in that order or lose the meaning; Greek can front the object for emphasis precisely because the article is holding the case.
The payoff is at its sharpest with foreign names, most of which do not decline at all in Greek. There the article is the only case marker in the phrase — remove it and the sentence has no grammar left.
Γνώρισα τον Τζον σε ένα συνέδριο στο Βερολίνο.
ghnórisa ton Dzon se éna sinédhrio sto Verolíno
I met John at a conference in Berlin.
Η νέα ταινία του Σπίλμπεργκ βγαίνει τον Δεκέμβρη.
i néa tenía tu Spílberg vyéni ton Dhekémvri
Spielberg's new film comes out in December.
Countries, cities, islands, rivers, mountains
Place names take the article too, and each one comes with a gender you have to learn with the word. There is no way to derive it from the map.
| Feminine (η) | Masculine (ο) | Neuter (το) | Plural (οι / τα) |
|---|---|---|---|
| η Ελλάδα, η Ιταλία, η Γαλλία, η Ισπανία, η Γερμανία, η Αγγλία, η Ολλανδία, η Ρωσία, η Τουρκία, η Κίνα, η Ινδία, η Αμερική, η Κύπρος, η Αίγυπτος | ο Καναδάς, ο Λίβανος, ο Παναμάς | το Βέλγιο, το Μεξικό, το Μαρόκο, το Ιράν, το Ισραήλ | οι ΗΠΑ, οι Κάτω Χώρες, τα Ηνωμένα Αραβικά Εμιράτα |
The feminine column is enormous — most country names in -ία, -ια, -α are feminine, which is the closest thing to a rule available. Watch η Κύπρος and η Αίγυπτος: they end in -ος and are still feminine. The full inventory with its patterns is on country names and their gender.
Η Ιταλία και η Ισπανία έχουν παρόμοιο κλίμα με την Ελλάδα.
i Italía ke i Ispanía échun parómio klíma me tin Eládha
Italy and Spain have a similar climate to Greece.
Ο Καναδάς έχει δύο επίσημες γλώσσες.
o Kanadhás échi dhío epísimes ghlóses
Canada has two official languages.
Cities are mostly neuter when foreign (το Λονδίνο, το Παρίσι, το Βερολίνο, το Άμστερνταμ) and feminine when Greek (η Αθήνα, η Θεσσαλονίκη, η Πάτρα, η Λάρισα), with a few masculines (ο Πειραιάς, ο Βόλος). Islands are overwhelmingly feminine, including the -ος ones: η Ρόδος, η Πάρος, η Μύκονος, η Λέσβος, η Κρήτη, η Σαντορίνη. Rivers and mountains are overwhelmingly masculine: ο Έβρος, ο Αχελώος, ο Δούναβης, ο Νείλος, ο Όλυμπος, ο Παρνασσός.
Το Λονδίνο μου φάνηκε πιο ακριβό από το Παρίσι.
to Londhíno mu fánike pio akrivó apó to Parísi
London struck me as more expensive than Paris.
Η Ρόδος έχει ήλιο ακόμα και τον Οκτώβρη.
i Ródhos échi ílio akóma ke ton Októvri
Rhodes still gets sun even in October.
Ο Όλυμπος είχε χιόνια μέχρι τον Ιούνιο φέτος.
o Ólimbos íche chiónia méchri ton Iúnio fétos
Olympus had snow until June this year.
Where the article disappears
Three contexts, and they are each worth knowing precisely.
1. Direct address (the vocative)
When you call someone rather than talk about them, the article goes. The vocative case takes no article in Greek — ever.
Μαρία, μου δίνεις λίγο νερό;
María, mu dhínis lígho neró;
Maria, could you pass me some water?
Γιώργο, σε ζητάει κάποιος στο τηλέφωνο.
Yórgho, se zitái kápios sto tiléfono
Giorgos, someone's asking for you on the phone.
The same holds for titles: you say ο κύριος Οικονόμου about him and κύριε Οικονόμου to him. The pairing is systematic and there are no exceptions.
Κύριε Οικονόμου, περάστε, σας περιμέναμε.
kírie Ikonómu, peráste, sas periméname
Mr Oikonomou, come in, we were expecting you.
2. Giving a name as information
After με λένε, ονομάζομαι and similar, the name is a bare predicate — it is content, not a referring expression, so no article. Compare the identifying είμαι ο/η + name, where the article is used because you are picking yourself out of a set.
Με λένε Δημήτρη, χαίρω πολύ.
me léne Dhimítri, chéro polí
My name's Dimitris, pleased to meet you.
Είμαι η Κατερίνα, μιλήσαμε χθες στο τηλέφωνο.
íme i Katerína, milísame chthes sto tiléfono
I'm Katerina — we spoke on the phone yesterday.
That contrast is genuinely logical rather than arbitrary. Με λένε Δημήτρη answers "what is your name?" and supplies a label. Είμαι η Κατερίνα answers "who are you?" and identifies a person the hearer is expected to place — which is exactly what a definite article is for.
3. Labels, lists and headlines
Timetables, signs, headlines, indexes, sports results and captions strip the article, the same way English strips it from telegraphic writing: ΑΘΗΝΑ – ΘΕΣΣΑΛΟΝΙΚΗ, Ολυμπιακός – Παναθηναϊκός 1-1, Πάτρα: νέα μέτρα. This is a register convention (formal / headline style), not a grammatical rule, and it never leaks into speech.
Colloquial destinations: a register contrast, not an error
In casual speech Greeks routinely drop both the preposition and the article before a destination. This is very widespread, entirely native, and marked (informal) — not a shortcut for learners to rely on in writing, but one you should recognise and understand.
Πάμε στη Θεσσαλονίκη το σαββατοκύριακο, βρήκα φθηνά εισιτήρια.
páme sti Thesaloníki to savatokíriako, vríka fthiná isitíria
We're going to Thessaloniki for the weekend — I found cheap tickets. (neutral — the form to write)
Πάμε Θεσσαλονίκη το σαββατοκύριακο, βρήκα φθηνά εισιτήρια.
páme Thesaloníki to savatokíriako, vríka fthiná isitíria
We're going to Thessaloniki for the weekend — I found cheap tickets. (informal spoken — very common, especially with cities and countries)
Two extras worth having early
Introductions. Presenting someone uses the article, since you are pointing at an identifiable person: Από εδώ ο Στέφανος, δουλεύουμε μαζί.
Από εδώ ο Στέφανος, δουλεύουμε μαζί εδώ και χρόνια.
apó edhó o Stéfanos, dhulévume mazí edhó ke chrónia
This is Stefanos — we've worked together for years.
Surnames used alone. A surname on its own also takes the article, and in the plural it means the family: οι Παπαδόπουλοι = "the Papadopoulos family", exactly like English "the Smiths".
Common Mistakes
1. Leaving the article off a name. The single most audible learner error in Greek.
❌ Γιάννης δεν ήρθε στη δουλειά σήμερα.
Incorrect — a name used as a subject takes the article: ο Γιάννης.
✅ Ο Γιάννης δεν ήρθε στη δουλειά σήμερα.
o Yánis dhen írthe sti dhuliá símera
Giannis didn't come to work today.
2. Keeping the article when you call someone. The vocative is always bare.
❌ Ο Γιάννη, έλα λίγο εδώ!
Incorrect — direct address takes no article: Γιάννη, έλα λίγο εδώ!
✅ Γιάννη, έλα λίγο εδώ, σε θέλω!
Yáni, éla lígho edhó, se thélo!
Giannis, come here a second, I need you!
3. Leaving a name in the nominative when it is the object. Since the article carries the case, the wrong article breaks the sentence.
❌ Περίμενα ο Γιώργος μία ώρα έξω από το θέατρο.
Incorrect — the object of περίμενα is accusative: τον Γιώργο.
✅ Περίμενα τον Γιώργο μία ώρα έξω από το θέατρο.
perímena ton Yórgho mía óra ékso apó to théatro
I waited an hour for Giorgos outside the theatre.
4. Adding an article after με λένε. The name there is a bare predicate.
❌ Με λένε ο Νίκος, χάρηκα.
Incorrect — after με λένε the name is bare and accusative: με λένε Νίκο.
✅ Με λένε Νίκο, χάρηκα πολύ.
me léne Níko, chárika polí
My name's Nikos, very nice to meet you.
5. Dropping the article from a place name in ordinary writing. The colloquial drop belongs to speech and only to destinations.
❌ Μου αρέσει πολύ Αθήνα τον χειμώνα.
Incorrect — a place name as subject or object takes the article: η Αθήνα.
✅ Μου αρέσει πολύ η Αθήνα τον χειμώνα.
mu arési polí i Athína ton chimóna
I really like Athens in winter.
Key Takeaways
- Greek names — people, countries, cities, islands, rivers, mountains — take the definite article in ordinary reference, where English uses none.
- The article is the name's case marker, and for indeclinable foreign names it is the only one: τον Τζον, του Σπίλμπεργκ.
- Each place name carries a fixed gender: η Ελλάδα, ο Καναδάς, το Βέλγιο, οι ΗΠΑ. Islands are mostly feminine even in -ος (η Ρόδος), rivers and mountains mostly masculine (ο Έβρος, ο Όλυμπος).
- The article disappears in three places: direct address (Γιάννη!, κύριε Οικονόμου!), naming after με λένε / ονομάζομαι, and headline / label style.
- Είμαι η Κατερίνα (identifying) versus Με λένε Κατερίνα (labelling) — a real semantic contrast, not a variant.
- Colloquial πάμε Θεσσαλονίκη is native and common (informal), restricted to destinations and to speech; write πάμε στη Θεσσαλονίκη.
- The morphology of the names themselves lives on declining Greek names and surnames.
