A more thorough explanation:

ne dona pas

Ne dona pas is a legal term that means "did not give" in Law French. It was used in the past as a general denial by a defendant in a formedon action. This plea was made when the plaintiff claimed the right to land under a gift of tail.

• John made a claim that he had the right to the land under a gift of tail. However, the defendant, Mary, pleaded ne dona pas, denying that she had given the land to John.
• In a formedon action, the defendant can use ne dona pas as a general denial to challenge the plaintiff's claim of the right to land under a gift of tail.

These examples illustrate how ne dona pas was used in the past as a legal term to deny a plaintiff's claim of the right to land under a gift of tail. The defendant would use this plea to challenge the plaintiff's claim and deny that they had given the land to the plaintiff.
