Tick (checkmark)

From Freepedia

A tick (known as a checkmark or check in American English) is a mark (✓) used to indicate the concept "yes", for example "yes, this has been verified" or "yes, I agree". Its opposite is the cross (✗), although the cross can also be positive, for example in elections.

As a verb, to tick (off) or to check (off) means to add such a mark. It is quite common, especially on printed forms, printed documents, and computers, for there to be squares in which to place ticks. In America, it is more common for people to check a square box with a cross (X); while in some European countries, it is more common for people to check a square box with a v-shaped checkmark.

The history of the checkmark goes back to the ancient Romans: When keeping checklists, they marked the items that they had checked with a V, standing for the Latin word vidi ("I saw").
