mistake vs error

Mistake implies a lapse in judgment or a careless slip, while error suggests a failure to meet a technical standard or a formal rule.

RememberMistakes are human slips; errors are technical failures.

Etymology

From Middle English mistaken, from Old Norse mistaka (“to take in error, to miscarry”); equivalent to mis- + take. Cognate with Icelandic mistaka (“to mistake”), Swedish missta (“to mistake”) (before apocope misstaga). The noun, which replaced earlier mistaking, is derived from the verb. Compare Swedish misstag (“mistake”, noun), Faroese mistak (“mitake”, noun), Icelandic mistak (“mistake”, noun).
