A letter closing is the final part of a written correspondence, where the sender wraps up their message and expresses a final sentiment. Common closings include phrases like "Sincerely," "Best regards," or "Yours truly." The choice of closing often reflects the relationship between the sender and the recipient, as well as the tone of the letter. After the closing phrase, the sender typically includes their name, and sometimes their title or contact information. This helps to formally conclude the letter and provides the recipient with a clear indication of who the message is from. Proper letter closing is important for maintaining professionalism in communication.
