A more thorough explanation:

Fictitious, adj. means something that is not real or true, especially in a legal context where it refers to a made-up story or situation that is used to help explain or solve a problem.

• A fictitious name was used in the book to protect the identity of the real person.
• The company created a fictitious employee to cover up their embezzlement scheme.
• In court, the lawyer used a fictitious scenario to illustrate his argument.

These examples show how the term fictitious is used to describe something that is not real or true, but is instead made up or imagined. In the first example, a fake name is used to protect someone's identity. In the second example, a fake employee is created to hide a crime. In the third example, a fake scenario is used to help explain a legal argument. All of these examples illustrate how the term fictitious is used in a legal context to describe something that is not real or true.
