A more thorough explanation:

Definition: Voco (voh-koh) is a Latin word that means "I call" or "I summon". In Roman law, it refers to the oral summoning of a defendant by a plaintiff to go before a magistrate. Vocation, on the other hand, refers to a person's regular calling or business, such as their occupation or profession.

• Vocatio in jus: This is a legal term that describes the plaintiff's oral summoning of a defendant to go before a magistrate. For example, if someone is suing another person for damages, they may use vocatio in jus to summon the defendant to appear in court.
• Vocation: A doctor's vocation is to heal people, while a teacher's vocation is to educate students.

These examples illustrate how voco and its related terms are used in different contexts. In Roman law, vocatio in jus was an important part of the legal process, while vocation refers to a person's chosen profession or occupation. By understanding these terms, we can better understand the legal and professional worlds around us.
