Secret languages

Secret languages are systems of communication designed to conceal meaning from unintended listeners. They can include coded words, symbols, or specialized grammar known only to a specific group. Examples include historical cipher systems, specialized jargon, or constructed languages like Esperanto. These languages serve to protect privacy, share confidential information, or strengthen group identity. While they vary in complexity, their primary purpose is to ensure that only those with the knowledge or key can understand the message, maintaining secrecy and secure communication.
