/ˈraɪdər/ – Noun
Definition: điều khoản bổ sung, phần phụ lục, giấy nối.
A more thorough explanation: In legal terms, a “rider” refers to an additional provision or amendment attached to a document, such as a contract, bill, or legislative proposal, that is not an integral part of the main text but is added to address specific issues or conditions. Riders are often used to modify or supplement the original content of the document.
Example: The rider signed a waiver before participating in the horseback riding activity.
