X mark
Spot indicates treasure
An X mark is a cross-shaped symbol used to indicate a selection, error, or location.
On ballots and forms, an X marks a choice.
Teachers use X marks to flag wrong answers, contrasting with checkmarks for correct ones.
On maps and in treasure-hunt lore, X marks the spot.
The symbol also represents a signature for those who cannot write their name.
