How it works

Grammar

Learn how endings express case, gender, number, tense, mood, and voice.

Five cases

Nominative, genitive, dative, accusative, and vocative endings show how a noun functions in a sentence.

Rich verb system

Verbs distinguish active, middle, and passive voice alongside several moods and aspect-based tense stems.

Pitch accent

Classical Greek accents originally marked pitch patterns rather than the stress system of Modern Greek.

  2. c. 500–323 BCE

    Classical Greek

    Attic became especially influential through Athens, drama, philosophy, history, and political prose.

  3. from the late 4th century BCE

    Koine Greek

    A widely shared form spread after Alexander's conquests and became the language of much Hellenistic and early Christian writing.
