🆚 Go to Comparative Table 🆚

The differences between Ancient Greek and Modern Greek are significant, particularly in terms of grammar, vocabulary, and phonetics. Some of the main differences include:

  1. Cases: Ancient Greek had 5 cases (nominative, vocative, accusative, genitive, and dative), while Modern Greek retains only the dative in fossilized structures of the Katharevousa.
  2. Number: Ancient Greek had a dual number, referring to two elements constituting a natural pair, while Modern Greek distinguishes between singular and plural.
  3. Vowel Length: Ancient Greek distinguished between long and short vowels, whereas Modern Greek does not.
  4. Diphthongs: The pronunciation of most diphthongs is different in Ancient and Modern Greek.
  5. Voice Infinitives: Ancient Greek has active and passive voice infinitives, while Modern Greek lacks this verb form.
  6. Desiderative Mood: Ancient Greek has an optional desiderative mood, which is replaced by a periphrasis in Modern Greek.
  7. Middle Voice: Ancient Greek had an intermediate voice between the active and the passive, known as the middle voice, which is not present in Modern Greek.
  8. Simplification: Modern Greek has undergone heavy grammatical simplification, making it more analytical and easier to learn for those who already know Ancient Greek.

Overall, while there are similarities between the two, Ancient Greek and Modern Greek are quite different, and learning one does not guarantee understanding of the other. A native Greek speaker who has never studied Ancient Greek would struggle to understand it, and a non-native student would likely need to study both Ancient and Modern Greek to achieve proficiency in both.
