Okay, past the halfway point. Let’s do this.
What’s in a name? Literally. Where does name come from?

As a noun, name comes from the Old English nama/noma, which means either name or noun. No, that sentence is not confusing. As a verb, it comes from namian, which just means to name. Those words both come from the Proto Germanic namon and before that the Proto Indo European nomn.
That’s it? It’s got a really simple explanation? It barely even changed over the last eight thousand years. How boring.
