Greek has four cases, which means pronouns, nouns, and articles 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 the complement of a verb.
|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.
|Ξέρω τον Μάρκο.||I know Markos.|
|Μίλω με τον γιατρό.||I’m talking to the doctor.|
3. Genitive case – Γενική
The genitive case is used for many different things, including
- Indirect objects
- Characteristics, nouns describing other nouns (e.g., history book)
(I haven’t studied this yet so will add examples later.)
FWIW: My Greek teacher says that the genitive is always introduced as the second case.
4. Vocative case – Κλητική
The vocative case is used only when addressing someone.
