Common language refers to a shared mode of communication that enables people to understand each other easily. It often includes widely recognized words, phrases, and expressions that are familiar to a particular group or community. This can be a specific language, like English, or a simplified version of a language that avoids complex jargon. In addition to spoken and written forms, common language can also encompass non-verbal cues, such as gestures and body language. It plays a crucial role in fostering effective communication in various settings, including education, business, and everyday interactions, helping to bridge gaps between different cultures and backgrounds.
