Eyeliner is formed from "eye" (from Old English "ēage", meaning the organ of sight) and "liner" (from the verb "line", meaning to mark or draw a line). The word "eyeliner" refers to a cosmetic product used to draw a line around the eyes.
Think of the word 'eye' as the organ of sight and 'liner' as something that marks or draws a line. This helps you remember that eyeliner is used to draw a line around the eyes.
