Greek has four cases, which means that three parts of speech – pronouns, nouns, and articles – each have up to four forms, depending on how they are used in a sentence. (And that doesn’t even include gender and number differences! More about those in future lessons.)

1. Nominative case – Ονομαστική

Also known as the "naming case," the nominative is the form of nouns and pronouns that serves as either the subject or subject complement.

Για παράδειγμα …

Ο Μάρκος μένει στην Αθήνα.   Markos lives in Athens.
Είναι γιατρός.   He’s a doctor.

2. Accusative case – Αιτιατική

The accusative is the case used for direct objects and objects of prepositions.

Για παράδειγμα …

Ξέρω τον Μάρκο.   I know Markos.
Μιλάω με τον γιατρό.   I’m talking to the doctor.

3. Genitive case – Γενική

The genitive case is used for many different things, including

  • Age
  • Possession
  • Characteristics, nouns describing other nouns

Για παράδειγμα …

τα κλειδιά του αυτοκινήτου   the car keys
το σπίτι της Μαρίας   Maria’s house

4. Vocative case – Κλητική

The vocative case is used only when addressing someone.
