Usage
What does prediction mean? A prediction is a statement about what someone thinks will happen in the future. People make predictions all the time. Some are very serious and are based on scientific calculations, but many are just guesses. Example: Here’s a prediction: in 20 years, we’ll all drive less and eat a lot less meat.
Etymology
Origin of prediction
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.
