Noun

Usage notes

 * This symbol is not usually used when ticking a box as a sign of acceptance; this is done with an X.
 * In Finland, the tick or checkmark ✓ is normally used to signify "incorrect" or "unacceptable". The habit has its origins in the old parish registers which had a column for registering parishioners' reading skills. X in that column meant "good", Y "fair", ⁒ "acceptable", and V "failed". V is also the first letter of the word.
 * A common usage of these symbols is in graded tests, where ⁒ is used to mark a correct answer and ✓ to mark a wrong answer.
