The Vietnamese word "thể lệ" is a noun that means "rules" or "regulations." It refers to a set of guidelines or instructions that govern how something should be done, such as in a game, competition, or organization.
Thể lệ cuộc thi này rất nghiêm ngặt.
(The rules of this contest are very strict.)
Bạn cần đọc thể lệ trước khi tham gia trò chơi.
(You need to read the rules before participating in the game.)
In more advanced contexts, "thể lệ" can be used in legal or formal documents to refer to regulations that must be followed in various situations, such as business practices or governmental procedures.
While "thể lệ" primarily means "rules," it can sometimes refer to the terms and conditions of a situation or event, emphasizing the structured framework that governs it.
