Decimate
Discover the surprising origin of the word 'Decimate'
You know the word "decimate." You've probably used it today. But here's what'll stop you cold: the word originally meant killing exactly one in ten. Not ninety percent. Not "total destruction." One. In. Ten. That specificity matters.
Most people think "decimate" comes from the word "decimal"--you know, the number system. They sound related, so it feels right. And technically, they share roots. But that's only half the story.
The real origin is Roman military discipline. The Latin word is *decimare*, from *decem*, meaning ten. When a Roman legion mutinied or performed catastrophically in battle, commanders could order *decimatio* -- soldiers drew lots, and every tenth man was executed by his own comrades. Historical accounts vary on how often this actually happened and exactly how it was carried out, but the practice was real enough to have its own name. It was punishment by arithmetic.
So when we say something "decimated the population" today, we're ghosting this horrifying Roman execution method. We've stretched the meaning to mean "destroyed most of" -- which is actually a corruption. But the DNA of the word still carries that grim precision: a systematic reduction. One out of ten, scaled infinitely outward.
Decimate is your word of the day. This is The Why of Words.
