A more thorough explanation:

Definition: Infitiatio (in-fish-ee-ay-shee-oh) is a Latin term used in Roman law to refer to the denial of a debt or liability, or the denial of a plaintiff's allegation. It is also spelled as inficiatio.

Example: If a person owes money to another person and denies that they owe any money, this is an example of infitiatio. Similarly, if a plaintiff makes an allegation against a defendant and the defendant denies the allegation, this is also an example of infitiatio.

The examples illustrate the definition of infitiatio by showing how it is used in the context of denying a debt or liability, or denying an allegation made by a plaintiff. In both cases, the person who denies the claim is using infitiatio as a defense against the claim being made against them.
