What does communication mean?
Communication is the process of conveying information, ideas, or feelings from one person or group to another, whether through speech, writing, gestures, or other signals. It lies at the heart of human interaction: relationships, organizations, and entire societies depend on it. The word can refer to the act itself, as in 'clear communication prevents misunderstandings', or to a specific message sent between parties, as in 'I received a communication from the office'. In its plural form, 'communications' usually denotes the means and systems of transmission, including telephone networks, broadcasting, and postal services. Because it spans everything from intimate conversation to global media, communication appears constantly in discussions of business, technology, psychology, and diplomacy. Derived from Latin roots meaning 'to make common', the word carries the idea that understanding is something shared rather than merely delivered.

Etymology of communication
Communication derives from the Latin verb 'communicare', meaning 'to share, make common', formed from 'communis', meaning common. It entered English in the early 15th century via Old French 'comunicacion', initially referring to the imparting or sharing of things, and later broadened to cover the transmission of ideas and information. It shares this Latin root with words such as community, commune, and communion.
