A salutation is a friendly greeting used at the beginning of a letter, email, or conversation. It sets the tone for the communication and can vary based on the relationship between the sender and the recipient. Common examples include "Dear" followed by a person's name, or a simple "Hello" or "Hi." In formal settings, using titles like Mr., Ms., or Dr. can show respect. In addition to written communication, salutations are also important in face-to-face interactions. A warm greeting, such as "Good morning" or "How are you?" helps establish a positive atmosphere. Overall, salutations play a key role in making connections and showing politeness.
