A more thorough explanation:

Definition: If he has made you secure. These were the initial words of a writ ordering the sheriff, upon receipt of security from the plaintiff, to compel the defendant's appearance in court.

Example: If a person is suing another person, they may need to provide security to ensure that the defendant will appear in court. The writ would begin with the words "si fecerit te securum" to indicate that the plaintiff has provided the necessary security.

The example illustrates how the term "si fecerit te securum" was used in legal documents to indicate that a plaintiff had provided security to ensure the defendant's appearance in court.
