Etymology: "Dottit" is the Scots form of "dotted," the past participle of a verb meaning to mark with small spots or points. The Scots spelling reflects the older Scots pronunciation and spelling of the same root as English "dot," which probably came into use in the Middle English period, though its exact earlier origin is uncertain. In Scots, the form is also used more loosely to describe someone who is dazed, forgetful, or slightly foolish, a sense that grows naturally from the idea of a mind gone patchy.
