A check mark, checkmark or tick is a mark (✓, ✔, etc.) used (primarily in the English speaking world) 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 use (most notably on election ballot papers), but otherwise usually indicates “no”, incorrectness, or failure.

History
The check mark is believed to have been created during the Roman Empire. "V" was used to shorten the word "veritas", meaning 'true'. This was used to indicate yes, true, or confirmed on items in a list. Over time, its design started to change. When people started attempting to speed-write, the right side became elongated. Whilst, the left side was similarly affected by ink pens of the time, in which the ink would not start flowing immediately when writing quickly resulting in the check mark we know today.
