A more thorough explanation:

Definition: Chirographum is a Latin term that refers to a handwritten document, typically an agreement or a debt acknowledgment, that is written by the debtor themselves. It is different from typographum, which refers to a printed document.

Examples: An example of a chirographum would be a handwritten IOU note that someone writes to acknowledge a debt they owe to another person. Another example could be a handwritten contract between two parties that outlines the terms of an agreement.

Explanation: Chirographum is a legal term that is used to describe a specific type of document. The key characteristic of a chirographum is that it is handwritten by the debtor themselves. This is important because it provides evidence that the debtor has acknowledged the debt or agreement in question. The examples given illustrate this definition by showing how a chirographum can be used in practice, such as in the case of an IOU note or a contract.
