The term "white line" has a simple etymology. It is generally used to refer to a line or mark that is colored white. The word "white" derives from the Old English word "hwīt", which is related to the Proto-Germanic word "hwītaz". This word ultimately goes back to the Proto-Indo-European root "*ḱweytos". "Line" comes from the Middle English word "line", which traces back to the Old English word "līne" and the Latin word "linea", meaning "a linen thread" or "string". Therefore, the combination of "white" and "line" in "white line" forms a compound word that describes a line or mark that is colored white.
