streamline
UK: ˈstriːm.laɪn | US: ˈstriːm.laɪn
vt. to design or shape for smooth, efficient movement (e.g., a car or process)
adj. having a smooth, efficient, or simplified form
n. a contour designed to minimize resistance to motion (e.g., in fluid dynamics)
The word "streamline" emerged in the mid-19th century, combining "stream" (Old English strēam, meaning "flowing water") and "line" (Latin linea, "thread or mark"). Initially used in fluid dynamics to describe the path of minimal resistance for liquids, it later metaphorically expanded to engineering (e.g., aerodynamic shapes) and business (efficiency optimization). The logic reflects nature’s efficiency—water flows smoothly around obstacles, inspiring human designs.
The new electric car was streamlined to reduce wind resistance.
We need to streamline our production process to cut costs.
