Adjective Agreement in Greek

Overview

Greek adjectives agree with the noun they modify in gender, number, and case. This three-way agreement is an essential A1 concept because adjectives appear in almost every sentence, from simple descriptions to complex narratives.

The most common adjective pattern follows the -ος/-η/-ο endings for masculine/feminine/neuter: καλός/καλή/καλό (good), μεγάλος/μεγάλη/μεγάλο (big). Some adjectives use -ος/-α/-ο or -ύς/-ιά/-ύ patterns, but the principle is the same -- the ending matches the noun's gender.

Adjectives can appear before or after the noun. When placed before, the adjective sits between the article and noun: ο καλός φίλος (the good friend). When placed after, the article is repeated: ο φίλος ο καλός. Both are correct, though the second form adds slight emphasis to the adjective.

How It Works

Core Concept

Adjectives agree in gender, number, case: καλός/καλή/καλό, μεγάλος/μεγάλη/μεγάλο. Placed before or after noun.

Key Patterns

Greek	English
ο καλός άντρας	the good man
η μεγάλη πόλη	the big city
το μικρό παιδί	the small child
οι καλοί φίλοι	the good friends

Common Adjective Pattern: -ος / -η / -ο

	Masculine	Feminine	Neuter
Nominative sg.	καλός	καλή	καλό
Genitive sg.	καλού	καλής	καλού
Accusative sg.	καλό(ν)	καλή	καλό
Nominative pl.	καλοί	καλές	καλά
Genitive pl.	καλών	καλών	καλών
Accusative pl.	καλούς	καλές	καλά

Alternative Pattern: -ος / -α / -ο

Some adjectives use -α instead of -η for the feminine: ωραίος / ωραία / ωραίο (beautiful), νέος / νέα / νέο (new/young).

Position of Adjectives

Adjectives can appear before or after the noun:

1. Before (default): ο καλός φίλος (the good friend)
2. After (emphatic): ο φίλος ο καλός (the friend, the good one)

When placed after, the article is repeated before the adjective. Both word orders are grammatically correct.

Common Mistakes

Confusing case forms

• Wrong: Using the nominative form where the accusative or genitive is required.
• Right: Match the case to the grammatical function (subject = nominative, object = accusative, possession = genitive).
• Why: Greek case endings carry meaning. Using the wrong case changes the sentence's meaning or makes it ungrammatical.

Translating directly from English

• Wrong: Applying English grammar rules or word order to Greek adjective agreement constructions.
• Right: Follow the Greek pattern, even when it differs significantly from English.
• Why: Greek and English express many ideas with fundamentally different structures. Direct translation often produces unnatural or ungrammatical results.

Neglecting agreement

• Wrong: Forgetting to adjust related words (articles, adjectives, pronouns) when using adjective agreement.
• Right: Ensure all elements in the phrase agree in gender, number, and case as required.
• Why: Greek is a richly inflected language where agreement is mandatory, not optional.

Usage Notes

At the A1 level, focus on recognizing and producing the most common patterns for adjective agreement. You do not need to master every exception yet -- building confidence with regular forms is more valuable at this stage. Pay attention to how native speakers use these patterns in everyday contexts like ordering food, asking for directions, and making small talk.

Greek speakers are generally patient and encouraging with learners. Even if you make mistakes with adjective agreement, context usually makes your meaning clear. The key is consistent practice with high-frequency forms, which will become automatic with exposure.

Practice Tips

1. Create personal example sentences: Write 5-10 sentences using adjective agreement that relate to your daily life. Personal relevance strengthens memory. For example, describe your morning routine, your family, or your plans for the weekend using the patterns from this lesson.

2. Active listening practice: When watching Greek videos or listening to podcasts, keep a tally of how often you hear adjective agreement patterns. Pause and repeat the sentences you hear. This bridges the gap between passive recognition and active production.

3. Progressive difficulty writing: Start with simple sentences, then gradually add complexity. First master the basic pattern, then combine it with other structures you know. Review your sentences after a few days to spot any persistent errors.
