Ministr
Ministr is a term with origins in Latin, meaning "servant" or "attendant." Historically, it referred to a high-ranking official in a government, particularly one who heads a ministry. In modern usage, a ministr is a member of the executive branch of government, responsible for a specific department or area of policy, such as finance, foreign affairs, or defense.
The role of a ministr typically involves developing and implementing government policies within their designated portfolio.
