A check mark, checkmark or tick is a mark (✓, ✔, ☑, etc.) used to indicate the concept "yes" (e.g. "yes; this has been verified", "yes; that is the correct answer", "yes; this has been completed", or "yes; this [item or option] applies to me"). The x mark is also sometimes used for this purpose (most notably on election ballot papers), but otherwise usually indicates "no", incorrectness, or failure.
As a verb, to check (off) or tick (off), means to add such a mark. Printed forms, printed documents, and computer software (see Checkbox), commonly include squares in which to place check marks.
The check mark is a predominant affirmative symbol of convenience in the English-speaking world because of its instant and facile composition. In other countries, however, the mark is more complicated. For example, it is common in Swedish schools for a ✓ to indicate that an answer is incorrect (while "R", from the Swedish rätt, i.e., "correct", is used to indicate that an answer is correct). In Finnish, ✓ stands for väärin, i.e., "wrong", due to its similarity to a slanted v. (The opposite, "right", is marked with , a slanted vertical line emphasized with two dots).
