A fluke is something good that happens purely by luck or accident, not through skill or planning. When a basketball player closes their eyes and tosses the ball backward over their head, and it somehow swooshes through the net, that's a fluke. When you guess randomly on a difficult test question and happen to choose the right answer, that's a fluke too.

The word suggests that what happened was unlikely and probably won't happen again. If a soccer player scores an amazing goal by accident when the ball bounces off their knee in just the right way, their teammates might say it was a fluke. A fluky goal is one that succeeded more through chance than talent.

People sometimes dismiss their own successes as flukes when they feel uncertain about their abilities, saying “I just got lucky” instead of recognizing the skill involved. But there's an important difference: if you study hard and do well on a test, that's not a fluke, that's preparation paying off. Real flukes are genuine accidents, rare shots, the times when chance alone creates an unexpected result.

The word can also describe the lucky accident itself: “That goal was a total fluke.” In sports, science experiments, and life, flukes remind us that sometimes randomness plays a bigger role than we'd like to admit.
