A more thorough explanation:

Definition: Invadiatio (in-vay-dee-ay-shee-oh) is a legal Latin term that refers to a pledge or mortgage.

Example: A person may use invadiatio to secure a loan by pledging their property as collateral. If they fail to repay the loan, the lender can take possession of the property.

This term is important in understanding the legal concept of securing a loan with collateral. Invadiatio is similar to the modern-day concept of a mortgage, where a borrower pledges their property as security for a loan. The examples illustrate how invadiatio was used in the past to secure loans and ensure repayment.
