Noun Gender in Greek

In Brief

Every Greek noun belongs to one of three grammatical genders: masculine, feminine, or neuter. In the basic subject form, the definite article makes the gender visible: ο άντρας “the man,” η γυναίκα “the woman,” and το παιδί “the child.” Endings provide useful clues, but the safest habit is to learn each noun together with its article.

Overview

A noun is a word for a person, place, thing, or idea, such as “teacher,” “city,” “book,” or “love.” In Modern Greek, every noun has grammatical gender: αρσενικό (masculine), θηλυκό (feminine), or ουδέτερο (neuter). Gender belongs to the noun itself. It is not something you choose according to the situation.

This is one of the first systems introduced at A1 because gender affects much more than the noun. Articles, adjectives, and some pronouns must agree with it—that is, they change form to match. Compare ο καλός φίλος “the good friend,” η καλή φίλη “the good female friend,” and το καλό βιβλίο “the good book.”

English usually does not assign gender to ordinary objects, so forms such as “the table” and “the book” give an English speaker no clue. Greek does: το τραπέζι is neuter, while το καρέκλα is not possible because καρέκλα is feminine: η καρέκλα. Gender often follows recognizable endings, but meaning alone cannot reliably predict it.

How It Works

The basic three-way pattern

The clearest gender marker is the singular definite article in the nominative case (the form normally used for the subject of a sentence).

Gender	Definite article	Example	Meaning
Masculine	ο	ο άντρας	the man
Feminine	η	η γυναίκα	the woman
Neuter	το	το παιδί	the child

The corresponding basic indefinite forms are ένας for masculine, μία/μια for feminine, and ένα for neuter: ένας φίλος, μια πόλη, ένα σπίτι. These forms mean “a/an” and are also related to the number “one.”

A bare vocabulary item such as δρόμος tells you less than ο δρόμος. Learn the whole unit aloud: ο δρόμος “the road,” not merely δρόμος. This also prevents you from relying too heavily on an ending that has exceptions.

Common ending clues

The following patterns are strong tendencies in the singular nominative. They are memory aids, not rules without exceptions.

Gender	Common endings	Examples
Masculine	-ος, -ας, -ης	ο φίλος (friend), ο πατέρας (father), ο μαθητής (student)
Feminine	-α, -η	η μέρα (day), η πόλη (city)
Neuter	-ο, -ι, -μα	το βιβλίο (book), το σπίτι (house), το μάθημα (lesson)

These clues are especially useful when meeting new words. A noun in -μα is very often neuter, and everyday nouns in -ι are commonly neuter. Likewise, many nouns in -ας or -ης are masculine.

The ending -ος deserves special care. It is often masculine—ο δρόμος, ο χρόνος, ο φίλος—but it can also be feminine: η οδός “road/street,” η μέθοδος “method,” η είσοδος “entrance.” A smaller group of nouns in -ος is neuter, including το μέρος “place/part,” το τέλος “end,” and το λάθος “mistake.” The article, not -ος by itself, gives the final answer.

Gender and biological sex

For people and some animals, grammatical gender often matches sex:

• ο άντρας — the man
• η γυναίκα — the woman
• ο γιος — the son
• η κόρη — the daughter

Some words form a masculine–feminine pair by changing the ending, as in ο δάσκαλος / η δασκάλα “the male/female teacher” and ο φίλος / η φίλη “the male/female friend.” Other pairs use entirely different words, such as ο άντρας / η γυναίκα.

However, grammatical gender is not a statement about sex. Το παιδί “the child” and το άτομο “the person/individual” are neuter grammatical nouns even when they refer to a boy, girl, man, or woman. Objects and abstract ideas also have gender: η αγάπη “love” is feminine, ο χρόνος “time” is masculine, and το πρόβλημα “problem” is neuter.

Agreement makes gender visible

An adjective describes a noun and normally changes to match its gender. In the common adjective pattern -ος / -η / -ο, the three forms line up like this:

Gender	Article + adjective + noun	Meaning
Masculine	ο καλός φίλος	the good friend
Feminine	η καλή φίλη	the good female friend
Neuter	το καλό παιδί	the good child

Demonstratives—words such as “this” and “that”—also agree: αυτός ο δρόμος “this road,” αυτή η πόλη “this city,” αυτό το σπίτι “this house.” Gender therefore remains important even when the noun’s own ending is not an obvious clue.

Gender does not change with case or number

Greek uses case, meaning that noun phrases change form according to their role in the sentence. For example, a subject commonly uses the nominative, while a direct object (the person or thing directly affected by an action) commonly uses the accusative.

• Ο φίλος έρχεται. — The friend is coming.
• Βλέπω τον φίλο. — I see the friend.

The article and noun endings change from ο φίλος to τον φίλο, but the noun remains masculine. Similarly, η γυναίκα becomes τη(ν) γυναίκα, and το παιδί remains το παιδί in this contrast. Number does not change gender either: το βιβλίο and τα βιβλία are both neuter.

One detail can surprise beginners: the plural nominative definite article is οι for both masculine and feminine nouns. Compare οι φίλοι “the male friends/friends” and οι φίλες “the female friends.” The noun ending and the surrounding agreement show the distinction.

Common Mistakes

Guessing from meaning instead of learning the article

• Wrong: ο παιδί
• Right: το παιδί
• Why: A child is a person, but παιδί is grammatically neuter. Natural sex does not determine every noun’s grammatical gender.

Treating every noun in -ος as masculine

• Wrong: ο είσοδος
• Right: η είσοδος
• Why: -ος is a common masculine ending, but some nouns in -ος are feminine and some are neuter. Memorize η είσοδος as one unit.

Mixing the article and adjective genders

• Wrong: η καλός φίλη
• Right: η καλή φίλη
• Why: The article and adjective must agree with the feminine noun φίλη.

Assuming an English “it” means Greek neuter

• Wrong: το πόλη because a city is “it” in English
• Right: η πόλη
• Why: English pronoun choice does not predict Greek grammatical gender. Greek assigns gender to ordinary objects and places too.

Thinking a changed ending means a changed gender

• Wrong idea: τον φίλο is no longer masculine because it does not end in -ς.
• Right analysis: ο φίλος → τον φίλο remains masculine.
• Why: The change marks case—from subject form to object form—not gender.

Using singular articles with plural nouns

• Wrong: το παιδιά
• Right: τα παιδιά
• Why: Gender stays neuter, but the article must also agree in number: singular το παιδί, plural τα παιδιά.

Usage Notes

In dictionaries, a noun may be labelled αρσ. (masculine), θηλ. (feminine), or ουδ. (neuter). Learner dictionaries may instead use m, f, and n. Even when a dictionary displays the noun without an article, check this label before using it.

Greek often omits an indefinite article where English uses one, especially after είμαι “I am/am/is/are” with professions or roles: Είμαι δάσκαλος “I am a teacher.” The missing article does not remove gender. A female speaker would normally say Είμαι δασκάλα. When an article is present, its form remains one of the most useful gender signals.

Some occupation nouns have established masculine and feminine forms, while usage for other titles can vary. At beginner level, learn the common pair supplied by a reliable dictionary or course rather than inventing a feminine form from a guessed ending.

Beyond the Basics

You do not need to master all of the following at A1, but these points explain patterns you will meet later.

Greek gender is attached to the lexeme—the dictionary word—not merely to its final letters. This is why identical-looking endings can belong to different genders. It is also why related words may have different genders: ο δρόμος “road” is masculine, while η οδός “road/street” is feminine.

Gender interacts with reference in pronouns. A pronoun may agree with the grammatical gender of the noun it stands for: Πού είναι η τσάντα; Αυτή είναι εδώ. “Where is the bag? It is here.” Greek uses the feminine form αυτή because τσάντα is feminine, even though English uses the gender-neutral “it.” With nouns referring to people, meaning and grammatical agreement can sometimes pull in different directions, especially with grammatically neuter words such as άτομο “person.” Such choices depend on the sentence and discourse, so follow natural examples rather than translating an English pronoun mechanically.

Diminutive forms—words that can suggest smallness or affection—are often neuter, even when the base word is not. For example, η γάτα “cat” is feminine, while το γατάκι “little cat/kitten” is neuter. The new derived word has its own grammatical gender.

Loanwords and indeclinable nouns can make their gender less visible because their ending does not follow a familiar Greek pattern. Their article and agreement reveal the accepted gender. This is another reason that article-plus-noun learning remains useful well beyond the beginner stage.

Finally, gender is only one part of agreement. As you progress, articles and adjectives will match nouns in gender, number, and case together. Knowing that πόλη is feminine is the foundation; later you will learn forms such as της μεγάλης πόλης “of the big city.”

Practice Tips

1. Make the article part of the word. Write and say ο φίλος, η πόλη, and το σπίτι, using three colors if visual grouping helps. Do not make flashcards with the bare noun on its own.
2. Sort new nouns by article, then test the endings. Keep three columns headed ο, η, and το. Notice patterns such as masculine -ας/-ης, feminine -α/-η, and neuter -ο/-ι/-μα, while marking exceptions such as η είσοδος and το λάθος.
3. Build short agreement chains. For each noun, add one adjective: ο νέος δρόμος, η νέα μέρα, το νέο βιβλίο. Then say a simple sentence with the phrase. This trains gender as something used across the whole noun phrase, not as an isolated label.
