A "dead language" is a language that no longer has native speakers. This means that no community uses it as their primary means of communication. Examples of dead languages include Latin and Ancient Greek, which are studied for their historical and cultural significance but are not spoken in daily life. Dead languages can still be important for understanding literature, history, and linguistics. Scholars often study them to gain insights into ancient civilizations and their cultures. While they may not be spoken, they can still influence modern languages and contribute to academic fields such as philology and archaeology.
