What are 'Initials' specifically referring to?

Initials specifically refer to the first letter(s) of a name, typically the first letter of each part of a person's name. For example, if someone's name is John Doe, their initials would be "J.D." This convention helps to identify individuals in a concise manner, emphasizing the important parts of their name without using the full name.

The concept of initials is crucial for forms and applications, like the USCIS N-400, where space may be limited, and providing the basic identification is necessary. The other options do not capture the specific nature of initials; they either refer to different aspects of a name or do not relate to the concept of initials at all.
