Root Explanation

Centerline → It is formed from "center" (from Old French *centre*, meaning the middle point) and "line" (from Latin *linea*, meaning a string or line). The word "centerline" refers to a line that indicates the middle point of something.

Memory Tip

Think of the 'middle point' ('center') and a 'string' or 'line' — together they form a centerline, which is the line that shows the middle.
