Check mark

Symbol often denoting 'yes' or 'correct'

A check or check mark, checkmark, tickmark or tick is a mark used in many countries, including the English-speaking world, to indicate the concept "yes". The x mark is also sometimes used for this purpose, but otherwise usually indicates "no", incorrectness, or failure. One of the earliest usages of a check mark as an indication of completion is on ancient Babylonian tablets "where small indentations were sometimes made with a stylus, usually placed at the left of a worker's name, presumably to indicate whether the listed ration has been issued."
