Chances are, you use some of these expressions in conversation frequently—maybe even every day. But where do they come from, anyway? We asked linguistics expert Arika Okrent, author of Highly Irregular and In the Land of Invented Languages, to weigh in.

1. By the Same Token

Bus token? Game token? What kind of token is involved here? Token is a very old word, referring to something that’s a symbol or sign of something else. It could be a pat on the back as a token, or sign, of friendship, or a marked piece of lead that could be exchanged for money. It came to mean a fact or piece of evidence that could be used as proof. By the same token first meant, basically, “those things you used to prove that can also be used to prove this.” It was later weakened into the expression that just says “these two things are somehow associated.”

2. Get on a Soapbox

The soapbox that people mount when they get on a soapbox is actually a soap box, or rather, one of the big crates that used to hold shipments of soap in the late 1800s. Would-be motivators of crowds would use them to stand on as makeshift podiums to make proclamations, speeches, or sales pitches. The soap box then became a metaphor for spontaneous speech making or getting on a roll about a favorite topic.

3. Tomfoolery

The notion of Tom fool goes a long way. It was the term for a foolish person as long ago as the Middle Ages (Thomas fatuus in Latin). Much in the way the names in the expression Tom, Dick, and Harry are used to mean “some generic guys,” Tom fool was the generic fool, with the added implication that he was a particularly absurd one. So the word tomfoolery suggested an incidence of foolishness that went a bit beyond mere foolery.

4. Go Bananas


The expression go bananas is slang, and the origin is a bit harder to pin down. It became popular in the 1950s, around the same time as go ape, so there may have been some association between apes, bananas, and crazy behavior. Also, banana is just a funny-sounding word. In the 1920s, people said “banana oil!” to mean “nonsense!”

5. Run of the Mill

If something is run of the mill, it’s average, ordinary, nothing special. But what does it have to do with milling? It most likely originally referred to a run from a textile mill. It’s the stuff that’s just been manufactured, before it’s been decorated or embellished. There were related phrases like run of the mine, for chunks of coal that hadn’t been sorted by size yet, and run of the kiln, for bricks as they came out without being sorted for quality yet.

6. Read the Riot Act

When you read someone the riot act you give a stern warning, but what is it that you would have been reading? The Riot Act was a British law passed in 1714 to prevent riots. It went into effect only when read aloud by an official. If too many people were gathering and looking ready for trouble, an officer would let them know that if they didn’t disperse, they would face punishment.

7. Hands Down

Hands down comes from horse racing, where, if you’re way ahead of everyone else, you can relax your grip on the reins and let your hands down. When you win hands down, you win easily.

8. Silver Lining

The silver lining is the optimistic part of what might otherwise be gloomy. The expression can be traced back directly to a line from Milton about a dark cloud revealing a silver lining, or halo of bright sun behind the gloom. The idea became part of literature and part of the culture, giving us the proverb every cloud has a silver lining in the mid-1800s.

9. Have Your Work Cut Out

The expression you’ve got your work cut out for you comes from tailoring. To do a big sewing job, all the pieces of fabric are cut out before they get sewn together. It seems like if your work has been cut for you, it should make job easier, but we don’t use the expression that way. The image is more that your task is well defined and ready to be tackled, but all the difficult parts are yours to get to. That big pile of cut-outs isn’t going to sew itself together!

10. Through the Grapevine

A grapevine is a system of twisty tendrils going from cluster to cluster. The communication grapevine was first mentioned in 1850s, the telegraph era. Where the telegraph was a straight line of communication from one person to another, the “grapevine telegraph” was a message passed from person to person, with some likely twists along the way.

11. The Whole Shebang

The earliest uses of shebang were during the Civil War era, referring to a hut, shed, or cluster of bushes where you’re staying. Some officers wrote home about “running the shebang,” meaning the encampment. The origin of the word is obscure, but because it also applied to a tavern or drinking place, it may go back to the Irish word shebeen for a ramshackle drinking establishment.

12. Push the Envelope

Pushing the envelope belongs to the modern era of the airplane. The flight envelope is a term from aeronautics meaning the boundary or limit of performance of a flight object. The envelope can be described in terms of mathematical curves based on things like speed, thrust, and atmosphere. You push it as far as you can in order to discover what the limits are. Tom Wolfe’s The Right Stuff brought the expression into wider use.

13. Can’t Hold a Candle

We say someone can’t hold a candle to someone else when their skills don’t even come close to being as good. In other words, that person isn’t even good enough to hold up a candle so that a talented person can see what they’re doing in order to work. Holding the candle to light a workspace would have been the job of an assistant, so it’s a way of saying "not even fit to be the assistant, much less the artist."

14. The Acid Test

Most acids dissolve other metals much more quickly than gold, so using acid on a metallic substance became a way for gold prospectors to see if it contained gold. If you pass the acid test, you didn’t dissolve—you’re the real thing.

15. Go Haywire

What kind of wire is haywire? Just what it says—a wire for baling hay. In addition to tying up bundles, haywire was used to fix and hold things together in a makeshift way, so a dumpy, patched-up place came to be referred to as “a hay-wire outfit.” It then became a term for any kind of malfunctioning thing. The fact that the wire itself got easily tangled when unspooled contributed to the “messed up” sense of the word.

16. Called on the Carpet

Carpet used to mean a thick cloth that could be placed in a range of places: on the floor, on the bed, on a table. The floor carpet is the one we use most now, so the image most people associate with this phrase is one where a servant or employee is called from plainer, carpetless room to the fancier, carpeted part of the house. But it actually goes back to the tablecloth meaning. When there was an issue up for discussion by some kind of official council it was on the carpet.
