Synonym discussion

Sense: noun/1

In British English, a 'tick' (✓) is the standard symbol for indicating that something is correct or completed, while a 'cross' (✗) marks an error or rejection. In American English, the same symbol is called a 'check' or 'check mark,' and the verb equivalent is 'to check' rather than 'to tick.' The noun 'tick' is also used informally to mean a moment ('I'll be there in a tick'), which can cause ambiguity — but in context, the ✓ symbol meaning is far more common in written references to forms and documents. Choose 'check mark' when writing for an international or American audience to avoid confusion.

Etymology

Old EnglishMiddle EnglishEnglish

The word 'tick' comes from Middle English 'tek' or 'tike,' which originally referred to the light, tapping sound of a clock mechanism. This onomatopoeic sense (imitating the actual sound) appeared in the 15th century. The noun sense for a small arachnid developed separately from a different Old English root 'ticia' related to 'tike' (a small creature). The 'check mark' sense grew out of the verb 'to tick' (mark with a light stroke) in the 18th century, and the 'credit' sense ('on tick') is believed to be a short form of 'on the ticket,' referring to an IOU or credit slip from the 17th century.
