contradict

Imagine two friends arguing about whether the sky is blue or green. If one friend says it's green while looking at a clearly blue sky, their words contradict what they can see. To contradict means to say the opposite of what someone else has said, or to say something that goes against the facts. You might contradict your own earlier statement, or contradict someone else's opinion. A detective might look for contradictions in a witness's story—inconsistencies that can suggest the person isn't being truthful. It's like building with mismatched pieces; things just don't fit together.

To contradict something is to assert the opposite of it—to deny its truth or validity. This can happen in several ways. You might directly contradict a statement by saying, "That's not true!" Or you could contradict someone through your actions; if you tell everyone you're on a diet but then sneak a slice of cake, your behavior contradicts your words.

Contradiction isn't always about simple disagreement. It often implies a logical inconsistency. For example, saying "All cats are black, and my cat is white" presents a contradiction because the second statement doesn't fit within the framework established by the first.

In legal settings, lawyers often try to find contradictions in witnesses' testimony to cast doubt on their credibility. In literature, characters might contradict themselves to reveal inner conflict or hidden motives. Even scientific theories can be contradicted by new evidence, leading to revisions and breakthroughs.

The word comes from the Latin contradicere, meaning "to speak against." So when you contradict something, you're essentially speaking against it—challenging its truthfulness or consistency. Whether it's a simple disagreement, a logical flaw, or a clash between words and actions, to contradict is to present opposing information that undermines the original claim.
