A more thorough explanation:

An error in a person's name is called error nominis. This mistake can be a small detail, like a misspelling or a wrong middle initial. It is different from error de persona, which is a mistake in identifying the wrong person.

Examples:

• Misspelling a name on a legal document
• Using a nickname instead of the person's legal name
• Writing the wrong middle initial on a form

These examples show how a mistake in a person's name can cause confusion or problems in legal or official situations. It is important to double-check the spelling and details of a person's name to avoid an error nominis.
