Odd words, old meanings

A cobweb vs. a spiderweb: Is there a difference?

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.

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.

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.

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.

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.

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.

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.

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.

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.

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".

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.

12 facts that people often get wrong

No one can claim to know everything, but most people go through life confident about certain things. However, some of these widely held beliefs are not actually correct, despite their popularity. Let’s have a look at some "facts" you might have gotten wrong!

The idea that insects—particularly mosquitoes—are not animals is widespread, but it’s also incorrect. In fact, insects are the most diverse group within the Animal kingdom, with more than a million species described and representing more than half of the animal population of the planet.

The mistake comes from not considering that "fruit" is not only a culinary term but also a botanical one. Botanically, a fruit is the part of a plant that develops from a flower and contains seeds. This makes tomatoes, peppers, cucumbers, eggplants, and many other foods that we call vegetables actually fruits in the scientific sense.

Countries have a political delimitation, while continents are divided according to geographical criteria. The Russian Federation is the largest country on Earth, bordering fourteen other countries and extending across eleven time zones. It spans across a good part of Eastern Europe, but also across the Ural mountains—one of the recognized borders between Europe and Asia—and stretches deep into northern Asia.

While cold weather isn’t harmless, it is not the direct cause of illnesses like the flu, which are caused by viruses. In colder months, people tend to spend more time indoors and often avoid ventilating rooms, creating conditions that make it easier for viruses to spread and cause illness.

Bats might not prefer to be out during bright daylight, but this does not mean that they are blind. In fact, many species have excellent eyesight, though it is adapted to low-light or nighttime conditions. On top of that, bats also use echolocation, which allows them to navigate and hunt with remarkable precision in complete darkness.

The belief that you must wait a full day before reporting someone missing is a myth popularized by movies and TV shows. In reality, the law does not require a waiting period. In fact, law enforcement agencies stress that the first 24 hours are often the most critical, so a missing person should be reported immediately.

Some man-made structures are visible from space without magnification, but despite popular belief, the Great Wall of China is not one of them. While it is quite long, being over 13,000 miles long, it is relatively narrow, and its earthy colors blend in with the surrounding landscape, making it nearly impossible to spot with the naked eye from orbit.

This one is tricky: Mount Everest is the highest mountain on Earth (29,032 feet)… if you measure the distance from sea level to peak. For the actual tallest mountain, the answer might vary depending on how you measure. Measured from base to summit, Mauna Kea in Hawaii is the tallest at 33,474 feet—though much of it is underwater. Mount McKinley (Denali) in Alaska rises about 18,000 feet from its base to the peak, making it the tallest mountain entirely above sea level. And Ecuador’s Mount Chimborazo, while shorter in height, is the farthest point on Earth from the planet’s center due to the equatorial bulge.

The Earth is tilted on an axis, which causes the amount of sunlight each hemisphere receives to change as it orbits the Sun. Because of this tilt, when the Northern Hemisphere is tilted toward the Sun and experiences summer, the Southern Hemisphere is tilted away and experiences winter—and vice versa. This is why the Southern Hemisphere celebrates Christmas during summer.

Standard medical advice is to gently guide a sleepwalker back to bed rather than waking them, but not because waking them is inherently dangerous. People tend to sleepwalk during deep sleep, so waking them up might startle them or cause confusion and disorientation.

Hair color and thickness are determined by genetics, not by shaving. Hair naturally gets thin at the ends, so when you shave it, the hair shaft appears to be thicker and darker because of the blunt cut. But it's just an optical illusion; the natural size of the shaft remains unchanged.

Coffee is a natural diuretic, meaning it can increase trips to the bathroom. However, the water in brewed coffee still contributes to your hydration and offsets its mild diuretic effect. If you consume coffee in moderation—3 to 5 cups a day, depending on your tolerance—you should be alright. However, drinking extra water on the side is never a bad idea.
