So… What’s an “-Ology,” Anyway?
Ever stumbled across a word ending in “-ology” and thought, That sounds impressive… but what does it even mean? You’re not alone. Most of us know the familiar ones—biology, psychology, geology—but then there are words like apiology, and suddenly your brain hits pause.
That’s where this Ology Vocabulary Quiz comes in. It’ll clear up the confusion—and throw in a few curveballs just to keep things interesting.
Here’s the deal: the suffix “-ology” comes from the Greek word logos, meaning “word” or “discourse.” Over time, in English, it evolved to mean “the study of.” So whenever you see an “-ology” word, think of it as a label for the study of something. And humans? We’ll study pretty much anything. From clouds to cheese to clowns (yes, really), there’s an academic term for it.
Whether you’re a trivia enthusiast, a lifelong learner, or just here to show off your vocabulary skills, you’re in the right place.
