Language systems refer to the structured ways in which humans communicate using symbols, sounds, and gestures. These systems include spoken languages, such as English and Spanish, as well as written forms, like Chinese characters and Latin alphabet. Each language system has its own set of rules, including grammar and syntax, which help convey meaning effectively. In addition to spoken and written languages, language systems can also encompass non-verbal communication, such as sign language and body language. These systems are essential for social interaction and cultural expression, allowing individuals to share ideas, emotions, and information across different contexts and communities.
