Formal address refers to the respectful way of speaking or writing to someone, often used in professional or official settings. It typically involves using titles, last names, or specific honorifics, such as Mr., Ms., Dr., or Professor, to show respect and maintain a level of professionalism. In many cultures, formal address is important in communication, especially in business, academia, or when interacting with authority figures. It helps establish boundaries and conveys a sense of respect. Understanding the appropriate use of formal address can enhance interpersonal relationships and facilitate effective communication.
