About this topic

The things we use without thinking usually arrived by an odd route. A packing material sold first as wallpaper, a fabric named after the French city that made it, a word for pay that goes back to a Roman ration of salt. This quiz collects the origins that survive in everyday language and objects, the kind of fact you half-remember hearing once and never confirmed. The explanations give the full story rather than the punchline, because in almost every case the route from there to here is the interesting part.

1The English word "salary" comes from the Latin word for which substance?
- A Silver
- B Salt Correct
- C Grain
- D Bronze
Answer: B. Salt

Why: It derives from the Latin salarium, connected to sal, meaning salt. Roman soldiers received an allowance tied to this valuable commodity, and the word for it drifted into meaning pay in general.
2Bubble wrap was originally marketed as which product?
- A A children's toy
- B Textured wallpaper Correct
- C Greenhouse insulation
- D Packing peanuts
Answer: B. Textured wallpaper

Why: Its inventors sealed two shower curtains together in 1957 hoping to sell it as wallpaper. That failed, and it only found its purpose when IBM needed to ship computers safely.
3The fabric "denim" takes its name from a town in which country?
- A Italy
- B Germany
- C Spain
- D France Correct
Answer: D. France

Why: It comes from serge de Nimes, a sturdy cloth from the French city of Nimes. "Jeans" has a separate origin, from Genoa in Italy.

- A Thirty
- B Seven
- C Fourteen
- D Forty Correct
Answer: D. Forty

Why: It comes from the Italian quaranta giorni, meaning forty days, the length ships were held offshore during plague outbreaks in Venice and Ragusa.
5Play-Doh was first sold as which household product?
- A A soap substitute
- B A wallpaper cleaner Correct
- C A floor polish
- D A modelling clay for sculptors
Answer: B. A wallpaper cleaner

Why: It was made to lift soot from wallpaper heated by coal fires. When homes switched to cleaner heating the market collapsed, and it was rebranded as a toy.
6Velcro was invented after its creator studied what?
- A Bird feathers
- B Burrs stuck to his dog's fur Correct
- C Spider silk
- D Fish scales
Answer: B. Burrs stuck to his dog's fur

Why: Swiss engineer George de Mestral examined the burrs under a microscope after a walk and found tiny hooks. He spent years reproducing the effect in fabric.

- A A chocolate bar melting in his pocket Correct
- B A light bulb glowing near a radar
- C A cup of tea boiling by itself
- D A metal spoon growing warm
Answer: A. A chocolate bar melting in his pocket

Why: Percy Spencer was working near an active radar set in 1945 when he noticed the chocolate had melted. He tested the effect with popcorn, and the microwave followed.
8The Frisbee is named after which business?
- A A shipping line
- B A pie company Correct
- C A newspaper
- D A rubber factory
Answer: B. A pie company

- B The mechanical typewriter Correct
- C The early computer terminal
- D The telegraph key

- B A Latin word for large
