Accuracy is how close something is to being exactly correct or true. It’s often used for measurements, facts, or answers.
From Latin 'accuratia' and 'accuratus', meaning 'done with care' or 'careful'. The root 'cura' means 'care', which is also in 'cure' and 'curator'.
Accuracy isn’t just about being right; it’s about being carefully right. The word literally grew out of the idea of taking care with details, which is exactly what you do when you aim for accuracy.
