A friend posted that "decimate" does not mean to completely destroy something.
This is a linguistic myth I keep seeing thrown around on social media.
I am assuming they are referring to the word origin regarding the Roman military punishment for cowardice or mutiny. The troops were divided into groups of ten, and one man from each group was chosen to be executed by the others.
So people will say the accurate definition of decimate is to reduce something by 1/10th.
But words evolve. Many are far removed from their origins. And the modern definition of decimate does actually mean to destroy a large percentage of something. An argument could be made "completely" destroy is outside that definition. Perhaps "effectively" destroy would be more accurate. And then annihilate would be to completely destroy.
But the 10% thing is no longer valid.
Linguistics does not care if the word has "deci" in it. Definitions are always derived from how the word is used and currently understood among a large populace.
This is a kind of know-it-all gotcha that people use to feel smart. But it really only shows their ignorance of how language works. And then people like my friend assume it is true and perpetuate this myth. And then I have to decide if I should embarrass them with a correction or just let it go and save myself some anxiety.
It's okay to be frustrated with popular usage. I am constantly annoyed that "resolution" is now used to denote pixel dimensions instead of effective detail. And decimate has a fascinating origin story that can be explained without claiming someone is using the word improperly. Otherwise, you are shaming people for using terms you fully understand. They communicated effectively and that's really all that matters.
