Why Do We Call Some Vents Registers?

Hi there, you have A Way with Words.

My name is Michael Kolakowski, calling from Papillion, Nebraska.

Papillion.

Oh, nice butterfly.

Yeah, cool.

Welcome to the show. What can we do for you, Michael?

I was doing some work around the house the other day, and I had to go to the hardware store and buy a couple of those heating registers, and I was thinking, why do we call them registers? What exactly do they register? Then I thought this would be a perfect question for you guys.

So you’re thinking of those devices that are on the wall or floor that either expel air or suck in the air? They regulate the flow, right? Really, it’s just like a vent cover. A vent. But sometimes they put out heat. Sometimes they put out cool air. Sometimes they’re the intake for the larger AC system, right?

That’s correct.

Okay, gotcha.

Right.

Why do we call them registers?

That’s a fantastic question that I don’t have the answer to.

Thanks for calling.

No, I know this is one of those things, Michael, that I looked into and I was not happy with anything that I found. I looked in historical dictionaries and I looked in expert texts where they talk about building, you know, installing these systems in houses. I looked in old newspapers to try to find early uses of it. And one thing that I found was pretty much in the 1600s, you find register being used to mean, how should I put this, on a chemistry apparatus where the results would appear. So, for example, if you combine this chemical with that chemical, this is where the third chemical or the fumes or the product would come out. So this is where you would register the effect, if that makes sense, the effect of all your experiments and your processes that you’re putting this stuff through. Imagine tubes and pipes and bubbling things and so forth. And at the end is the product. If you think about registering as being where something is imprinted or something is established, that’s kind of what we’re talking about here. But it’s still not clear to me why they chose that as register. I’m still not 100% sure.

And then it expands by the 1800s when we get to the steam era and the industrial era. A register is used for a wide variety of inflows and outflows, giant ones and small ones, on tiny little machines and vast ones in houses and businesses, and even sometimes on automobiles and aircraft and that sort of thing. And a register now pretty much is, as you said, just a vent, any place where air moves back and forth for whatever reason.

Yeah, I’m thinking of organ pipes as well, right?

Yeah, they have different registers.

Yeah, well, they talk about registering the pipes of an organ where you set them to work in a specific way for a particular performance.

Right, yeah.

That would make more sense to me, I think.

Yeah.

But that’s a really specialized use of register, and I don’t think it’s related to the specific origin of the wider register, meaning event.

All right, fair enough.

Yeah, that’s the best I could do.

I’m sorry, but you know what? We have people all over the world listening to this show, and I know that we have construction workers. Who we have truck drivers and people with specialized knowledge. And if somebody has a better idea of where this register comes from, by all means, let us know, 877-929-9673.

Thanks, Michael.

Sure thing.

Thank you.

Take care.

Thanks for calling.

Bye-bye.

-huh.

Bye-bye.
