Noun Gender in Greek

Overview

Every Greek noun belongs to one of three grammatical genders: masculine (αρσενικό), feminine (θηλυκό), or neuter (ουδέτερο). This is a foundational concept at the CEFR A1 level because gender determines how articles, adjectives, and pronouns agree with nouns throughout a sentence.

Unlike some languages where gender is unpredictable, Greek provides strong clues through noun endings and the definite article. Masculine nouns typically take ο, feminine nouns take η, and neuter nouns take το. The ending of the noun itself often signals the gender, making the system more learnable than it might initially appear.

Mastering gender assignment early will save you from compounding errors later. Nearly every grammatical structure in Greek -- from adjective agreement to case declension -- depends on getting the gender right from the start.

How It Works

Gender by Ending and Article

Gender	Article	Common Endings	Examples
Masculine	ο	-ος, -ας, -ης, -ές	ο δρόμος (road), ο πατέρας (father), ο μαθητής (student), ο καφές (coffee)
Feminine	η	-α, -η, -ος (few)	η μέρα (day), η τέχνη (art), η οδός (road)
Neuter	το	-ο, -ι, -μα, -ος (few)	το βιβλίο (book), το παιδί (child), το γράμμα (letter), το δάσος (forest)

Detailed Rules

1. Masculine nouns most often end in -ος (ο δρόμος), -ας (ο πατέρας), or -ης (ο μαθητής). Some end in -ές (ο καφές). The article ο is your most reliable gender marker.

2. Feminine nouns most often end in -α (η μέρα) or -η (η τέχνη). A small group ends in -ος (η οδός, η μέθοδος) -- these look masculine but take the article η.

3. Neuter nouns end in -ο (το βιβλίο), -ι (το παιδί), or -μα (το γράμμα). Some end in -ος (το δάσος, το λάθος) and look masculine but take the article το.

4. People nouns often come in gender pairs with different endings:

Masculine	Feminine	Meaning
ο φίλος	η φίλη	friend
ο δάσκαλος	η δασκάλα	teacher
ο μαθητής	η μαθήτρια	student
ο γιατρός	η γιατρός	doctor (same form)

Grammatical vs. Natural Gender

Grammatical gender does not always match natural gender. The word το κορίτσι (the girl) is grammatically neuter despite referring to a female, because it ends in -ι. Similarly, το αγόρι (the boy) is neuter.

Examples in Context

Greek	English	Note
ο ήλιος	the sun	Masculine, ends in -ος
η θάλασσα	the sea	Feminine, ends in -α
το νερό	the water	Neuter, ends in -ο
ο καφές	the coffee	Masculine, ends in -ές
η πόλη	the city	Feminine, ends in -η
το σπίτι	the house	Neuter, ends in -ι
ο γιατρός / η γιατρός	the doctor (m/f)	Same form, different article
το πρόβλημα	the problem	Neuter, ends in -μα
ο δάσκαλος / η δασκάλα	the teacher (m/f)	Different ending per gender
η μέθοδος	the method	Feminine despite -ος ending
το κορίτσι	the girl	Neuter despite female referent
ο μαθητής / η μαθήτρια	the student (m/f)	Different suffix per gender

Common Mistakes

Assuming -ος is always masculine

• Wrong: Treating η μέθοδος as masculine because it ends in -ος.
• Right: Η μέθοδος is feminine -- the article η signals this.
• Why: A small group of feminine nouns end in -ος (η οδός, η μέθοδος, η είσοδος). The article is the surest gender indicator.

Ignoring gender in article choice

• Wrong: *το γυναίκα (using neuter article with feminine noun)
• Right: η γυναίκα
• Why: The article must match the noun's gender. Getting this wrong cascades into adjective, pronoun, and verb errors.

Assuming gender from meaning

• Wrong: Treating το κορίτσι (the girl) as feminine because it refers to a female.
• Right: Το κορίτσι is grammatically neuter (ends in -ι).
• Why: Grammatical gender and natural gender do not always align. Agreement follows grammatical gender: το μικρό κορίτσι (the little girl -- neuter adjective).

Forgetting that some nouns in -ος are neuter

• Wrong: Assuming ο δάσος for "the forest."
• Right: Το δάσος -- neuter despite the -ος ending.
• Why: A handful of neuter nouns end in -ος (το λάθος, το δάσος, το μέρος). These must be memorized with their article.

Usage Notes

Gender is not decorative in Greek -- it is structurally load-bearing. Every article, adjective, demonstrative pronoun, and participle must agree with the noun's gender. Getting gender wrong at A1 will compound into errors at every subsequent level.

Compared to French or German, Greek gender is relatively predictable from noun endings. The system rewards learning nouns with their articles from day one. Dictionaries always list the article alongside the noun for this reason.

A few occupation nouns use the same form for both genders, distinguished only by the article: ο/η γιατρός (doctor), ο/η δικηγόρος (lawyer). Newer usage in Greek increasingly creates feminine forms (η γιατρίνα), though this varies by region and speaker preference.

Practice Tips

1. Always learn nouns with articles: Never memorize πόλη alone -- learn η πόλη. This single habit prevents most gender errors and will serve you throughout your Greek studies.

2. Sort by ending: Group vocabulary by ending (-ος, -α, -η, -ο, -ι, -μα) and notice the gender patterns. This builds intuitive prediction of gender for new words.

3. Test yourself with flashcards: Write just the noun on one side and the article + noun on the other. Quiz yourself on the article before flipping. Focus extra attention on tricky nouns where ending and gender do not match (η μέθοδος, το κορίτσι).
