"LWC" is an acronym which means "Language of Wider Communication." LWC refers to a language that is used as a means of communication between people who speak different native languages. It's often a common language that people from diverse linguistic backgrounds use to communicate with each other.
For example, English is considered a language of wider communication because it's widely spoken and understood in many parts of the world, even by people whose first language is not English. In international settings like business, diplomacy, or tourism, English often serves as the LWC because it enables people from different countries to understand each other and work together effectively.
