The word line also originates from Old English line, and has varied meanings such as a mark made on a surface, a boundary, or a row of text.
When these two words are combined, overline refers to a line drawn or placed above something, often used in typography or mathematics to indicate emphasis, a title, or a mark connecting multiple elements.
In summary, the etymology of overline is derived from the combination of the Old English word over and the Old English word line.
