The concept of dialogue, both linguistically and terminologically, is markedly different from intertwined concepts such as debate, argumentation, and negotiation. Dialogue is considered one of the methods used in any human discourse. In this research, we shed light on its clarification and discussion. Subsequently, we delve into the concept of interactive communication in dialogue, emphasizing that dialogue is based on the foundation of understanding, which involves agreement between individuals to achieve specific goals they aim for. Furthermore, we discuss the importance of dialogue, both internally and externally, and highlight the obstacles that should be avoided in dialogue.
