Natural languages are the languages that have developed naturally among people through use and social interaction. They are distinct from constructed languages, which are deliberately created. Examples of natural languages include English, Spanish, and Mandarin, each with its own unique grammar, vocabulary, and pronunciation. These languages are essential for communication and cultural expression. They evolve over time, influenced by social, political, and technological changes. Natural languages can be spoken, written, or signed, and they play a crucial role in shaping human identity and community.
