First recorded in 1555–65; from Latin praedictiōn-, stem of praedictiō “prophecy”; equivalent to predict + -ion
Explanation
I have a prediction: You’ll know what this word means by the time you finish reading this explanation. A prediction is what someone thinks will happen. A prediction is a forecast, but not only about the weather. Pre means “before” and diction has to do with talking. So a prediction is a statement about the future. It’s a guess, sometimes based on facts or evidence, but not always. A fortune teller makes a prediction using a crystal ball. A meteorologist uses maps and scientific data to tell us about the possibility of rain, snow or sunshine. And when I made the prediction that you would understand what this word meant, it was based on instinct, a gut feeling telling me what would happen next.
