To make a prediction: to forecast, foretell, or estimate a future event on the basis of knowledge and reasoning; to prophesy a future event on the basis of mystical knowledge or power.
"The meteorologist used historical data and current weather patterns to predict a severe storm for the weekend."
In plain English: To predict is to say what you think will happen before it actually does.
"The meteorologist predict that heavy rain will arrive by evening."
Usage: Use predict when you base your statement about a future event on evidence or logical reasoning rather than mere guesswork. Avoid using it for supernatural claims like prophecy unless emphasizing that such predictions are based on specific analysis.
The word "predict" entered English in the early 17th century from Latin praedicare, meaning "to mention beforehand." It is formed by combining the prefix for "before" with a verb meaning "to say," reflecting its original sense of speaking about something prior to it happening.
