What is the best definition of "ratify"?

The term "ratify" means to confirm or approve something, often in the context of formal agreements, treaties, or legislation. When a legislative body or governing authority ratifies an agreement, it signifies that they officially accept and endorse the terms of that agreement, giving it legal effect and authority. This process is vital in governance as it ensures that any significant decisions or treaties go through a formal approval process, reflecting the consent of the governing body or the electorate.

In contrast, the other definitions do not align with the established meaning of "ratify." Rejecting or denying pertains to disapproval and does not capture the essence of approval inherent in ratification. Analyzing or reviewing implies a deliberative process without a necessary outcome of approval or confirmation. Creating or establishing suggests the initiation of something new rather than the acceptance of something that already exists. Thus, the best definition of "ratify" is confirming or approving, reflecting its official and affirmative nature in governmental and legal contexts.
