An x mark (also known as a cross, x, ex, exmark or into mark[1]) is a mark (x, ×, X, ✕, ☓, ✖, ✗, ✘, etc.) used to indicate the concept of negation (for example "no, this has not been verified" or "no, I don't agree") as well as affirmation (for example in election ballot papers or in x marks the spot). It is often used opposite the check mark or tick (or the O mark used in Japan, Korea and Taiwan).
In some areas it's common for people to check a square box with a cross rather than a check mark, while in others the check mark (✓) or even a v mark[citation needed] is used.
It is also used as a replacement for a signature for a person who is blind or illiterate and thus cannot write his or her name.[2] Typically, the writing of an X used for this purpose must be witnessed to be valid.
As a verb, to ex (or x, notably one of the shortest English words)[3] off/out or to cross off/out means to add such a mark. It is quite common, especially on printed forms and document, for there to be squares in which to place x marks, or interchangeably checks.
It is also traditionally used on maps to indicate locations, most famously on treasure maps.
