While both "immediate" and "instant" describe something that happens quickly, there's a subtle difference in their usage. "Immediate" suggests something that happens without delay, but there might still be a brief period of time involved. "Instant," on the other hand, implies absolute speed; something that happens in an instant, without any perceptible delay. Think of it this way: "immediate" is fast, while "instant" is lightning fast.
Here are some example sentences to illustrate the difference:
Notice how "instant" often implies a more sudden and intense experience than "immediate." While the meanings are closely related, using the right word adds precision to your writing. Using the wrong word can alter the meaning of your sentence, even slightly.
