im-PECH-oo-uhs
His impetuous decision to quit his job left him scrambling for options.
Fun Fact
“Impetuous” comes from Latin impetere, meaning “to attack.” It describes decisions made in the heat of the moment—often dramatic, sometimes disastrous. Romeo and Juliet? Totally impetuous. But so are startup founders, comedians, and adventurers—when it works, it’s brilliant.
ih-LOO-sih-dayt
(verb) To make something clearer or easier to understand by explaining it in detail and with precision.
The professor didn’t simplify the theory — she elucidated it, walking the room through each layer until the complexity itself became comprehensible.
Elucidate derives from the Medieval Latin elucidare, meaning “to make light” or “to illuminate” — built from e- (“out”) and lucidus (“bright” or “clear”), itself from lux meaning “light.” The same root gives us lucid, translucent, illuminate, and elucidate — a family of words all built around light as the mechanism of understanding. It entered English in the 16th century, carrying its Latin sense of bringing something out of darkness and into clarity without reducing or distorting it in the process.
Fun Fact
Richard Feynman — Nobel Prize-winning physicist and one of history’s great elucidators — developed what became known as the Feynman Technique: if you cannot explain something in simple terms, you don’t understand it yet. He applied this ruthlessly to his own thinking, refusing to hide behind jargon and insisting that genuine understanding always produces clarity rather than complexity. His lectures on physics are still considered models of elucidation decades after his death — not because he simplified quantum mechanics but because he illuminated it from enough angles that the shape of the thing became visible. He reportedly said that if he couldn’t explain something to a first-year student, he didn’t really know it himself.
