A more thorough explanation:

Intercedere

Intercedere is a Latin term used in Roman law. It means to take responsibility for someone else's debt. This is usually done by acting as a surety for the person.

1. John interceded for his friend by agreeing to pay his debt if he couldn't.

2. Mary interceded for her sister by co-signing her loan.

These examples show how intercedere is used in Roman law. In both cases, someone is taking responsibility for another person's debt. John and Mary are acting as sureties for their friends and family members. This means that if the original debtor cannot pay their debt, John and Mary will be responsible for paying it instead.
