Etymology
Origin of incorrect
First recorded in 1400–50; late Middle English, from Latin incorrectus “not corrected”; equivalent to in- 3 + correct
Explanation
Incorrect things are wrong or mistaken. Driving the incorrect direction on the highway can be dangerous. Turn around! Using the incorrect name when you greet someone (or eating your soup with the incorrect spoon at a fancy dinner) can be embarrassing. A doctor giving you the incorrect diagnosis is never good. When something is correct, it's proper, accurate, truthful, or without errors, and you get incorrect by adding the "not" prefix, in-.
