Provide an example of a salutation.

A salutation is a greeting used in a letter or other written or non-written communication. Salutations can be formal or informal depending on the context and the relationship between the people communicating. Here is an example of a formal salutation:

"Dear Mr. Smith,"

This salutation is appropriate for a professional or formal setting where you are addressing someone by their surname. It is commonly used in business correspondence, formal letters, and emails when the gender of the recipient is known and the relationship is not personal.

For a less formal or more personal context, you might use a salutation like:

"Hi John,"

This is a casual greeting suitable for someone you know on a first-name basis or when the communication is informal, such as in a text message or a casual email to a colleague or friend.
