Dear (surname)
Dear (surname) is a salutation commonly used in formal correspondence, particularly in business or professional settings. It indicates a level of respect and formality that is greater than using only a first name, but less formal than addressing someone by their title (e.g., "Dr. Smith," "Professor Jones").
The use of "Dear (surname)" suggests that the writer either does not know the recipient well enough to use their first name or prefers to maintain a professional distance. It acknowledges the recipient's position or authority without being overly familiar.
The term "Dear" in this context functions as a polite and respectful opening. The inclusion of the surname ensures that the correct person is being addressed, especially in environments where multiple individuals share the same first name. The absence of a professional title further indicates a relationship that is less hierarchical than one might expect with such a formal opening.
