A more thorough explanation:

Definition: Vocatio in jus is a Latin term used in Roman law. It refers to the oral summoning of a defendant by a plaintiff to appear before a magistrate. The plaintiff would formally request the defendant to accompany them.

In ancient Rome, if someone had a legal dispute with another person, they would use vocatio in jus to summon the other person to court. For example, if someone owed money to another person and refused to pay, the creditor could use vocatio in jus to bring the debtor to court and settle the matter.

Definition: Vocation refers to a person's regular calling, business, occupation, or profession.

Some examples of vocations include teaching, nursing, engineering, and accounting. If someone is a teacher, their vocation is teaching. If someone is a nurse, their vocation is nursing.

Definition: Vociferatio is a Latin term used in history. It refers to an outcry or hue and cry.

In medieval times, if someone committed a crime, the villagers would use vociferatio to alert others and chase after the criminal. For example, if someone stole a chicken, the villagers would shout and make noise to alert others and catch the thief.
