Attic Dialect is a form of Ancient Greek that was spoken in the region of Attica, which includes the city of Athens. It emerged around the 5th century BCE and became the standard dialect for literature, philosophy, and public discourse in ancient times. This dialect is known for its clarity and elegance, making it the preferred choice for many famous writers, including Plato and Aristotle. Over time, Attic Dialect influenced other Greek dialects and laid the foundation for Koine Greek, which became the common language of the Hellenistic world.
