Communication is defined as the exchange of facts, ideas, opinions, or emotions to create mutual understanding. It involves more than just spoken or written words, including attitudes, gestures, actions, and feelings. Barriers to effective communication can occur when the message is filtered or misrepresented, potentially causing misunderstandings. There are several types of barriers, including semantic barriers due to differences in understanding, psychological barriers from emotional states, organizational barriers from policies and relationships, and personal barriers stemming from individual factors. Overcoming barriers requires identifying their causes and taking measures such as ensuring messages are clearly expressed, assumptions are clarified, proper feedback is provided, and communication is tailored to the receiver's needs.
