Definite Articles in Greek

In Brief

Greek has several forms for English the. Choose the form to match the noun's gender (masculine, feminine, or neuter), number (singular or plural), and case (the noun's role in the phrase): ο άντρας, η γυναίκα, το παιδί, but βλέπω τον άντρα. Learn each noun with its nominative article, then learn how the article changes when the noun changes role.

Overview

The definite article points to a person, thing, or idea treated as identifiable: το βιβλίο means “the book.” Unlike English the, however, the Greek article changes form. It agrees with its noun, meaning that the article and noun show the same gender, number, and case. This makes the article a valuable clue to the grammar of the whole phrase.

This is an A1 foundation. You first need to know that Greek nouns have three grammatical genders: masculine, feminine, and neuter. Grammatical gender is a noun class; it does not always describe biological sex. For example, το κορίτσι (“the girl”) is grammatically neuter. If terms such as nominative and accusative are unfamiliar, do not worry: they simply label the job a noun phrase is doing in a sentence.

English-speaking learners face two separate challenges. First, English has only one unchanging the, so it gives you no habit of matching an article to a noun. Second, Greek and English do not always use definite articles in the same places. The forms themselves are compact; the lasting skill is learning the article together with the noun and recognizing the phrase's role.

How It Works

The complete modern Greek table

Case	Masculine singular	Feminine singular	Neuter singular	Masculine plural	Feminine plural	Neuter plural
Nominative	ο	η	το	οι	οι	τα
Genitive	του	της	του	των	των	των
Accusative	τον	την	το	τους	τις	τα

There is no separate vocative article. The vocative is the form used when directly addressing someone, and normally appears without the definite article: Γεια σου, Μαρία! (“Hello, Maria!”), Κύριε Παπαδόπουλε! (“Mr Papadopoulos!”).

Notice several useful patterns:

• Masculine and feminine are identical in the nominative plural: οι.
• All three genders use των in the genitive plural.
• Neuter nominative and accusative forms are identical: το in the singular and τα in the plural.
• The article does not tell you everything by itself. του can be masculine or neuter, so the noun and the wider context still matter.

Nominative: the subject and naming form

The subject is the person or thing that performs the action or is described. The nominative is also the dictionary-style form commonly used when learning a noun.

• Ο άντρας περιμένει. — The man is waiting.
• Η πόρτα είναι ανοιχτή. — The door is open.
• Το παιδί κοιμάται. — The child is sleeping.
• Οι φίλοι έρχονται. — The friends are coming.

This is why vocabulary is best learned as ο άντρας, η πόρτα, το παιδί, not as isolated άντρας, πόρτα, παιδί. The article immediately records the noun's gender.

Accusative: objects and most prepositional phrases

The direct object is the person or thing directly affected by an action. Greek normally marks it with the accusative:

• Βλέπω τον άντρα. — I see the man.
• Ανοίγω την πόρτα. — I open the door.
• Διαβάζω το βιβλίο. — I read the book.

Most everyday prepositions also take the accusative. These include από (“from”), με (“with”), για (“for/about”), χωρίς (“without”), and σε (“in/at/to”):

• με τη φίλη μου — with my friend
• από το γραφείο — from the office
• για τους μαθητές — for the students

The preposition σε combines with the definite article. These contractions are obligatory in normal modern Greek:

σε + article	Contracted form	Example	Meaning
σε + τον	στον	στον κήπο	in/to the garden
σε + την	στην	στην πόλη	in/to the city
σε + το	στο	στο σπίτι	in/at/to the house
σε + τους	στους	στους φίλους	to the friends
σε + τις	στις	στις γυναίκες	to the women
σε + τα	στα	στα παιδιά	to the children

The English translation depends on context because σε can correspond to in, at, or to: Είμαι στο σπίτι (“I am at home/in the house”), but Πηγαίνω στο σπίτι (“I am going home/to the house”).

Genitive: possession and close relationships

The genitive commonly links one noun to another. It often expresses an owner, source, or close relationship and may translate as English of or an English possessive:

• το βιβλίο του μαθητή — the student's book / the book of the student
• η τσάντα της γυναίκας — the woman's bag
• το χρώμα του αυτοκινήτου — the colour of the car
• τα παιχνίδια των παιδιών — the children's toys

Greek places the genitive phrase after the noun it describes. Both the article and noun take genitive forms. The singular article reveals the gender of the following noun: του μαθητή is masculine, της γυναίκας feminine, and του παιδιού neuter. In the plural, των serves all three genders.

Agreement across a noun phrase

An adjective describing the noun normally agrees too. An adjective is a describing word such as “good” or “new.” Compare:

• ο καλός φίλος — the good friend
• η καλή φίλη — the good (female) friend
• το καλό βιβλίο — the good book
• τα καλά βιβλία — the good books

Do not choose the article from the noun's ending alone. Endings provide useful clues, but there are exceptions. Learn η οδός (“the street”), for instance, even though -ος often occurs on masculine nouns.

Definite does not simply mean “mentioned before”

Use the article when the listener can identify what you mean from the conversation, situation, or shared knowledge:

• Κλείσε την πόρτα. — Close the door. (the relevant door is clear)
• Πού είναι το κινητό μου; — Where is my phone?
• Ο ήλιος λάμπει. — The sun is shining.

Without an article, a noun may be non-specific, describe a category or role, or form part of a fixed expression. Compare Θέλω καφέ (“I want coffee”) with Θέλω τον καφέ (“I want the coffee,” a specific one).

Common Mistakes

Using the nominative article for an object

• Wrong: Βλέπω ο άντρας.
• Right: Βλέπω τον άντρα.
• Why: The man is the direct object of βλέπω, so the phrase must be accusative, not nominative.

Matching by natural sex instead of grammatical gender

• Wrong: η κορίτσι
• Right: το κορίτσι
• Why: κορίτσι is grammatically neuter even though it refers to a girl. Learn every noun with ο, η, or το.

Treating every plural οι as masculine

• Wrong assumption: οι γυναίκες must be masculine because it begins with οι.
• Right analysis: οι γυναίκες is feminine plural.
• Why: Masculine and feminine share nominative plural οι. The noun and any adjectives reveal the gender.

Leaving σε separate from the article

• Wrong: σε το σπίτι, σε την Αθήνα
• Right: στο σπίτι, στην Αθήνα
• Why: In standard modern Greek, σε contracts with a following definite article.

Copying English article use word for word

• Wrong: Μου αρέσει μουσική. when you mean music as a general idea
• Right: Μου αρέσει η μουσική.
• Why: Greek often uses the definite article with general classes and abstract ideas where English uses no article. Conversely, a profession after είμαι usually has no article: Είμαι μηχανικός (“I am an engineer”).

Confusing τις and της

• Wrong: της γυναίκες for “the women” as an object
• Right: τις γυναίκες
• Why: τις is feminine plural accusative; της is feminine singular genitive. Their similar sound makes this a common listening and spelling error.

Usage Notes

Greek uses articles with personal names

In ordinary Greek, personal names commonly appear with an article: ο Νίκος, η Μαρία. The form changes with the name's role: Βλέπω τον Νίκο (“I see Nikos”), το σπίτι της Μαρίας (“Maria's house”). English usually omits the here, so translating one word at a time is misleading.

Articles are also frequent with countries, cities, geographical features, days, and seasons, though usage depends on the name and construction: η Ελλάδα, στην Ελλάδα, η Αθήνα, στην Αθήνα, τη Δευτέρα (“on Monday”), το καλοκαίρι (“in summer/the summer”). Store common place names together with their article and contracted forms.

General statements often take the article

Greek frequently presents a whole class with a plural definite article: Οι γάτες αγαπούν τη ζέστη (“Cats like warmth”). It also uses articles with many abstract nouns: Η αγάπη είναι σημαντική (“Love is important”). English commonly uses a bare plural or bare abstract noun instead. This is a tendency, not a command to put an article before every noun; context and established expression still matter.

Final ν in τον and την

The written masculine accusative article is τον. The feminine την may appear as τη before many consonants, while την is retained before vowels and sounds represented by letters or combinations such as κ, π, τ, ξ, ψ, μπ, ντ, γκ, τσ, and τζ: την Αθήνα, την πόρτα, but commonly τη φίλη. Speech, house style, and editorial practice vary, and learners will encounter both τη and την. This sound-based alternation does not change the case or meaning.

Beyond the Basics / Advanced Use

You do not need to master the following details at A1, but they explain forms you will meet later.

The article can turn other words into noun-like expressions

Greek can place an article before an adjective, participle, adverbial expression, or other unit and let the whole expression function like a noun phrase. This process is sometimes called substantivization—using a non-noun as if it were a noun:

• οι νέοι — young people / the young
• το καλό και το κακό — good and evil / the good and the bad
• οι εργαζόμενοι — the employees / those who work

The article supplies gender, number, and case, while context supplies the understood noun or category.

Demonstratives normally keep the article

English says “this book,” not “this the book.” Greek standard noun phrases normally use a demonstrative plus article:

• αυτό το βιβλίο — this book
• εκείνη η γυναίκα — that woman
• αυτά τα παιδιά — these children

The demonstrative can also follow: το βιβλίο αυτό. The difference involves emphasis and style, but the article remains part of the definite noun phrase.

Formal and fossilized older forms

Formal writing and fixed expressions preserve traces of older Greek, including dative forms of the article that are not productive in everyday modern Greek: εν τω μεταξύ (“in the meantime”), εν τη πράξει (“in practice,” formal), and τοις εκατό in percentages. Treat these as learned expressions unless you are studying formal or literary Greek. Ordinary modern Greek uses nominative, genitive, and accusative as described above.

Meaning can shift with article presence

Article choice can contrast an identifiable item with a substance, activity, role, or non-specific quantity:

• Πίνω καφέ. — I drink coffee / I am drinking coffee.
• Πίνω τον καφέ. — I am drinking the coffee (the particular one).
• Είναι γιατρός. — She/he is a doctor.
• Είναι ο γιατρός. — She/he is the doctor (the identified doctor).

These contrasts are better learned as meanings in context than as a rule that English articles always predict Greek ones.

Practice Tips

1. Record nouns as three-part chunks. Write the nominative article, noun, and meaning: η πόρτα — door. Then add one accusative chunk, such as ανοίγω την πόρτα, so gender and case become part of the memory.
2. Transform one phrase through the cases. Start with ο φίλος (“the friend”), make it an object in βλέπω τον φίλο, then make it a possessor in το σπίτι του φίλου. Repeat with one feminine and one neuter noun.
3. Listen for article–noun pairs, not isolated articles. In audio, mark phrases such as στο σπίτι, της Μαρίας, and οι φίλοι. Contractions and the short forms τη/την become much easier when learned as sound chunks.
