Fun Fact
“Fallacious” comes from the Latin fallacia, meaning “deception” or “trickery.” The term is closely linked to logical fallacies—errors in reasoning that often appear persuasive but are fundamentally flawed. Common examples include the slippery slope fallacy and ad hominem attacks. Recognizing fallacious reasoning is a key skill in debate, critical thinking, and media literacy, helping people avoid being misled by faulty logic.
(noun) The range of one’s knowledge, understanding, or awareness.
Quantum physics lies far beyond my ken, no matter how many articles I read.
Ken comes from Old English cennan, meaning “to know” or “to make known,” and is closely related to Middle English and Scots usage where it meant knowledge, perception, or recognition. Over time, the word narrowed to describe the limits of what someone knows or understands, which is why it’s often used today in phrases like “beyond my ken.”
