Initials are the first letters of a person's name, often used to represent their full name in a shorter form. For example, if someone's name is John Smith, their initials would be J.S.. Initials can be used in various contexts, such as signing documents, creating monograms, or identifying individuals in a more concise way. In addition to personal names, initials can also refer to organizations or brands. For instance, the initials NASA stand for the National Aeronautics and Space Administration. Using initials helps simplify communication and can make names easier to remember or recognize.
