Communication is the process of transmitting information, ideas, and attitudes from one person to another through shared symbols. It is a two-way process of exchanging verbal and nonverbal messages between a sender and receiver. Effective communication occurs when the message conveyed is clear, the purpose is achieved, and there is constructive feedback. Communication can be verbal, involving spoken or written words, paraverbal through tone and pace of speech, or nonverbal including body language. Verbal communication aims to have people understand the intended message.
