A more thorough explanation:

Definition: Inficiatio is a term used in Roman law to refer to the denial of a debt or liability, or the denial of a plaintiff's allegation.

Example: If someone owes you money and they deny that they owe you anything, that is an example of inficiatio.

Explanation: Inficiatio is a legal term that refers to the act of denying a debt or liability. This can happen in a court of law when a plaintiff makes an allegation against a defendant, and the defendant denies the allegation. For example, if someone sues another person for not paying back a loan, and the defendant denies that they ever borrowed any money, that would be an example of inficiatio.
