Salutations are greetings used to acknowledge someone when you meet or communicate with them. They can be as simple as saying "hello" or "hi," or more formal like "good morning" or "greetings." Salutations help set the tone for a conversation and show respect or friendliness towards the other person. In written communication, such as letters or emails, salutations often include phrases like "Dear Recipient's Name" or "To whom it may concern." Using the right salutation is important because it reflects your relationship with the person and the context of your message, whether it's casual or professional.
