Is that some sort of a cross between pulverise and virulent?
Well, no, it's not. But it still sounds jolly nasty and dangerous, doesn't it.
And it is dangerous, too. Dangerous, and almost certainly lurking near you.
Under the bed, perhaps.
Oh, yes. All that sneezing, those red-rimmed eyes, that blocked-up nose, the absolute need to spend several hours cleaning before your mother-in-law comes round?
Yes, I said mother-in-law. That's because mothers-in-law are the the traditional scourge of the pulverulent.
So. Listen to me. You're going to have to get to work, aren't you. A pair of old underpants will do if you can't find anything better.
That's a dust mite.
Word Not To Use Today: pulverulent. This word, which means crumbling to, or covered in, dust, comes from the Latin pulverulentus, from pulvis, dust.
