The Vietnamese word "chủ lực" is a noun that translates to "main force" or "driving force" in English. It refers to the primary or most important group, element, or factor that plays a crucial role in achieving a goal or objective.
In more complex discussions, you can use "chủ lực" to refer to strategic initiatives or vital resources that are pivotal for success: - "Công nghệ thông tin là chủ lực trong sự phát triển của doanh nghiệp hiện nay." (Information technology is the driving force in the development of businesses today.)
While "chủ lực" primarily refers to a main force, it can also imply leadership or dominance in various fields, such as leadership in a project or dominance in a market.
