You might forget where you left your keys or your glasses, but some things are forever imprinted in your memory one way or another. And for those things you simply can’t seem to remember, some useful mnemonic devices can help you. For example, how can you remember the presidents on our bills? And what about all the spelling rules our language has? Is it "gray" or "grey"? Don’t worry, we’ve got you covered. Keep reading and learn a few tricks.

The faces on US bills

You may handle bills every single day, but can you answer whose face is on each one? You don’t need to remember; this mnemonic device will do it for you: The phrase "When Jeff Left Home, Jack Got Fat" gives you the answer. As you can notice, the first letter of each word stands for the last name of the president or founding father: Washington, Jefferson, Lincoln, Hamilton, Jackson, Grant, and Franklin.

Knuckle months

Yes, we keep lots of calendars, but sometimes we have to double-check if a month has 30 or 31 days. Has this happened to you? If it has, next time you’ll want to use your knuckles. The rule is simple: Make two fists and count across your knuckles and the dips between them. Months that land on knuckles have 31 days. The dips are the shorter months, February being the shortest, naturally.

"Righty tighty, lefty losey"

Have you ever had to try a few times before knowing whether you were loosening or tightening that screw? Well, with this rhythmic phrase, you won’t need to do that anymore. If you turn right, you’ll be making it tight. On the other hand, if you turn left, you’ll loosen it.

Gray or Grey?

English spelling keeps everyone on their toes, and certain words have regional rules that make everything worse. Nobody can remember them all, so this device comes in handy. When you don’t know whether it is "gray" or "grey," think of it this way: Gray, with an A as in America. Grey, with an E, as in England.

How to spell "necessary"

"Necessary": This is another word with a spelling that can create a few problems. And the mnemonic device for this one is picturing a T-shirt. You know how a T-shirt has one "Collar" (that’s one C) and two Sleeves (that’s two S)? That’s it, spelling solved.

"HOMES" of the lakes

Back in school, memorizing the Great Lakes could feel like a geography pop quiz. Simply the word "HOMES" is a trick that many teachers share with their students. Why HOMES? Because each letter represents a lake: Huron, Ontario, Michigan, Erie, and of course, Superior.

"My Very Educated Mother Just Served Us Nachos"

Just as with any other long list, remembering the order of the planets in our solar system is no piece of cake. But this fun phrase has the answer to your prayers, it’s not bout nachos, but about the names of the planets in order: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.

"Never eat soggy waffles"

This one sounds like breakfast advice, but it’s actually a compass lesson. The first letters match the four cardinal directions in clockwise order: North, East, South, West. Many kids learned this one in school, and plenty of adults still repeat it quietly when trying to picture a map in their heads.

Left or right?

This may sound silly, but many people struggle to point left; most need more than just a second to figure out which one is actually left. But many have discovered something quite useful: hold up both your hands and use your thumb and index finger to do an "L." Can you see which one forms a clear letter? That’s left, of course.

"Large Elephants Jump Slowly And Sink Rapidly"

Is this connected to the Constitution? Yes, it is. Civics teachers sometimes lean on this unusual sentence to remember the seven articles of the US Constitution. Each word stands for one: Legislative, Executive, Judicial, States, Amendment, Supremacy, and Ratification. Now you just have to remember this funny phrase.

Odd words, old meanings

These 10 idioms and phrases are still in use, but don’t always make sense

Published on April 22, 2026

How much is a notch when it comes to volume? Who is Bob, and why is he everyone’s uncle? What is the difference between a spider web and a cobweb? Languages change with time and use, and English is no exception, but some phrases remain frozen in time, and while we still use them, we don’t always know their literal meaning. Here are 10 idioms and words that don’t make sense, but once did.

To a T

We often use the phrase "to a T" (sometimes spelled "to a tee") to indicate something done perfectly, with precision. But is it about the letter "T"? Not really. The original phrase used to be "to a tittle," with tittle being the proper name for the dot of the "i" or the "j," and it conveyed the idea of doing something accurately, down to the smallest detail. Eventually, "tittle" was shortened to "T," but the phrase had already stuck, even if its literal meaning was lost.

Fathom

Although "fathom" might sound very formal, we all know that it is synonymous with "understand." But did you know that fathom is actually a nautical unit of measurement? From the Old English fæðm ("the span of the arms" or "embrace"), it represented the distance between the left and right fingertips of outstretched arms. Eventually, a "fathom" was standardized to about six feet or two yards, and was mainly used by sailors to measure water depth. It was this connection with depth that led the word to take on a figurative meaning of "getting to the bottom" of something, or understanding it thoroughly.

Red herring

Popularly, we understand that a "red herring" is something meant to give false clues or distract from another pressing issue. But why a herring? Herrings turn red when smoked and also acquire a strong, pungent smell, which made them a great tool for training hunting dogs, as the smell of the fish covered the trail of the prey. As a metaphor, though, it was popularized in the early 19th century by journalist William Cobbett, who used it to describe how the press was easily swayed by false news.

Rule of thumb

If something is a "rule of thumb," it means that it’s a common guideline, usually based on experience rather than science. In its origins, this phrase was quite literal: thumbs served as a rule. Tradesmen often used the width and length of their thumbs to take and remember measurements, a system that, though practical and effective, only worked for the owner of the thumb in question. Its use as an idiom comes from 17th century writers comparing this popular method with more scientific measuring systems.

Turn it down a notch

If someone asks us to "take it down a notch," how much should we lower our volume? With "notch," this idiom refers to mechanical dials, like the ones used in a radio, where the notches signal the different levels. And while radios only date back to the 20th century, the roots of this idiom go all the way back to the 17th century and to the phrase "take it down a peg," related to wooden pins used for measurements.

Cobweb

Is there a difference between a cobweb and a spiderweb? Although they are synonymous, most dictionaries will make the distinction that "cobweb" is particularly used for dusty, abandoned spiderwebs. But what does the "cob" part mean? "Cobweb" is derived from the Middle English coppeweb, composed of coppe ("spider") and web ("woven fabric"). If we go one step further, coppe comes from the Old English attorcoppe ("spider"), a mix of attor ("poison") and coppe ("head" or "round thing"). So, despite the slight difference in their actual use, "cobweb" and "spiderweb" mean the same thing.

Break the ice

It isn’t difficult to see how "breaking the ice" might have originated from people actually breaking ice, but what many ignore is that this custom (and the phrase) is rooted in diplomacy and trade. When large trade vessels were unable to advance due to frozen rivers, canals, or harbors, it was common to send people in a small boat to "break the ice" and allow the ship to continue its course. In some places, however, locals would send "icebreakers" to clear the path for a foreign vessel as a welcome and a sign of goodwill. The metaphorical use of the phrase exists in many languages, but it was first recorded in English in the 16th century.

Let one’s hair down

The idea of "letting down your hair" is popularly associated with relaxing and letting formalities aside, but the phrase is rooted in an actual Medieval and Renaissance custom. Traditionally, single women would keep their hair loose and uncovered, but would pin it up once they married. It was not proper for a married woman to be seen in public with their hair down, something they would only do in the comfort of their home, foregoing elaborate hairstyles and uncomfortable pins. Eventually, loose hair lost its social status meaning, but the connection with relaxation remained.

Bob's your uncle

According to historians, no one knows who Uncle Bob is, or what his connection is with simple and easily accomplished tasks, but popular folklore claims to have the answer. According to this theory, the phrase refers to British Prime Minister Robert Gascoyne-Cecil (who went by Bob), appointing his nephew Arthur Balfour as Chief Secretary for Ireland, a position he was woefully unqualified for, but that was made possible because "Bob’s your uncle".

Midwife

Have you ever wondered why midwives have that name? After all, there is nothing "mid" nor necessarily "wifely" in helping someone give birth. The answer takes us back to Old English, where mid meant "with" or "together with," and wif (the origin of "wife") meant "woman," "female," or "lady," and not necessarily a married female. First recorded around the year 1300, "midwife" was an accompanying person (typically a woman) who assisted mothers during labor. Although the literal meaning of the term is lost to us, the importance of the role was surely the reason this word survived through the centuries.
