I'm writing a story, and I have a Russian character whose last name I want to be based off the Russian word for dust. (Like in the Christian saying, "ashes to ashes, dust to dust.")
I've been doing my best with online English-to-Russian dictionaries, but I don't completely trust them. Here are two Russian words for "dust" that I found:
pil' / пыль
prah / прах
My best guess was Prakhov (hence my username). Does that work? I'm afraid it loses the meaning of "dust."
