Every word here is one you use without thinking, and every one of them started out meaning something stranger. Only well documented origins are included, so nothing rests on a good story alone.
Etymology is a field with a serious folklore problem. Neat acronyms and tidy anecdotes spread far faster than the real answer, which is usually a slow drift of sound and sense across several centuries and at least two languages. The honest test is whether the older form is actually written down somewhere, and for the words in this quiz it is. What emerges is a pattern rather than a set of curiosities. Words rarely arrive with their modern meaning attached. They get borrowed for one narrow purpose, wander into a metaphor, and stay there long after anyone remembers the literal image they started from.
Every question in this quiz is listed below with its correct answer and the reasoning behind it. Play first if you would rather not see the answers — or read through as a study sheet.
Play it insteadAnswer: D. A little mouse
Why: Latin musculus is a diminutive of mus, "mouse", apparently because a flexing bicep moves under the skin like a small animal. The same Latin word also gives us the shellfish called a mussel.
Answer: C. Left, or on the left-hand side
Why: Latin sinister simply meant left, and picked up its ominous sense from divination, where signs appearing on the left were read as unfavourable. Its opposite, dexter, survives in dexterous.
Answer: B. Dressed in white
Why: Roman office-seekers wore a specially whitened toga, so a candidatus was literally the man in white. The root candere, "to shine white", also lies behind candid and incandescent.
Answer: A. Bad star
Why: It reached English through Italian disastro, combining a negative prefix with astro, "star", reflecting the belief that misfortune came from an unfavourable alignment. Consider is often traced to the same astrological vocabulary.
Answer: D. Someone you share bread with
Why: The parts are com-, "with", and panis, "bread". The same panis gives us pantry, and the English word "lord" has a comparable history, coming from an Old English compound meaning loaf-keeper.
Answer: C. Arabic
Why: It comes from al-kuhl, the fine dark powder used as eye cosmetic, and shifted through the idea of a substance refined by distillation. Algebra, alkali and algorithm arrived by the same route.
Answer: B. Foolish or ignorant
Why: It goes back to Latin nescius, literally "not knowing". The sense travelled through fussy and then precise before settling on pleasant, which is why an older text can call a distinction a nice one.
Answer: A. Cow
Why: Edward Jenner used material from cowpox and called it variolae vaccinae, from vacca, "cow". Pasteur later extended the word to every preparation of the kind as a deliberate tribute to Jenner.
Answer: D. To tear flesh
Why: The verb sarkazein is built on sarx, "flesh", and described stripping meat from the bone. The same root gives sarcophagus, a coffin of limestone that was thought to consume the body inside it.
Answer: C. A ball of thread
Why: The older spelling was clew, meaning a ball of yarn, and the detective sense grew out of the story of Theseus unwinding thread to find his way back through the labyrinth. The thread sense survived for centuries alongside the new one.
