Language is an abstract and complex system of word meanings, symbols, and rules (grammar) that are shared by members of a culture and used for communication and representing all aspects of that culture. It is not limited to spoken or written words but also includes gestures, facial expressions, and other forms of nonverbal communication that convey meaning within a social context. Language is fundamental to human interaction, social organisation, and the transmission of culture from one generation to the next. It shapes how we think, perceive the world, and construct our social reality. The diversity of human languages reflects the rich tapestry of human cultures and the different ways in which societies have developed to understand and interact with their environments.
