Q&A: Why is it called a ‘dry run’?

Each week here at the Australian Writers’ Centre, we dissect and discuss, contort and retort, ask and gasp at the English language and all its rules, regulations and ridiculousness. It’s a celebration of language, masquerading as a passive-aggressive whinge about words and weirdness. This week, the big dry…

Q: Hi AWC, do you think we need to start rehearsing these chats?

A: That’s a terrible idea. They’d be far more boring.

Q: So you’re saying we shouldn’t do a “dry run”?

A: Yes, that’s what we’re say— Okay, where are you going with this?

Q: Haha, yeah, it’s my question for this week. WHY do we call something a “dry run”?

A: You’re of course referring to the literal phrase that Macquarie Dictionary defines as “a test exercise or rehearsal”. Any ideas where it might come from?

Q: A desert marathon?

A: Nice guess, but nothing like that at all. 

Q: What about Prohibition and having no alcohol?

A: Not bad, but it looks like we need to go back earlier – to the late 1880s and fire stations. 

Q: Ooooh can I slide down the pole?

A: Well, we’re not actually there, but sure.

Q: Weeeeeeeeeee!

A: Finished?

Q: Yes, thanks. Carry on.

A: There is a large body of evidence to support the theory that a “dry run” originated with fire departments. They famously spend a lot of their time waiting to attend actual fires. And when they’re not doing that?

Q: Pole dancing?

A: No! They’re testing their equipment.

Q: Oh yes, that makes more sense.

A: Many of their tests were simply to practice the procedure of getting out the hose and attaching it to a hydrant and so on. In those cases, they’d do a “dry run” – everything but turn on the water. 

Q: Yeah that’s smart. And water-wise.

A: There are fire station logs from this era showing “dry runs” as a thing in training. And in 1910, a report of a contest between departments that had different categories including “wet tests” and “dry runs”.

Q: Mystery solved! But when did it start getting used for everything else?

A: By the 1930s it was being applied to other specific areas. Bricklaying apprentices performed a “dry run” laying bricks. Same for carpenters without glue. But it was once the military got hold of it that it really took off.

Q: Don’t they usually create fires, not put them out?

A: Haha, well, the “fire” in this case is of the “ready-aim-fire” variety! A dry run was seen as a military exercise that didn’t use live ammunition.

Q: And what about just rehearsals in general?

A: The term seems to have exploded in the 1940s.

Q: Exploded? I thought we weren’t using live ammunition?

A: Hilarious. It entered the dictionary in 1941 and the use of it in World War II no doubt affected its usage too, as a lot of military vernacular spread across the globe during this period. 

Q: So today it can still mean all those things in fire stations or battalions, but we could also just use it for any practice or rehearsal, yeah?

A: That’s right. If you had a presentation to give tomorrow, you might suggest a dry run the day before. A theatre production might do a dry run without costumes, and so on. Another area it is used specifically in today is software design – with a “dry run” being a specific test stage when creating an app or program, etc.

Q: From fire management to file management!

A: That’s a good one. You’re on fire today.

Q: Hey, I make the jokes around here…
