While postal employees pride themselves on delivering mail in rain, sleet, and snow, they can still be impeded by sloppy handwriting. That’s why the U.S. Postal Service has a team of keen-eyed employees whose job is to determine where to send letters and packages with illegible addresses. More than 730 people work at the USPS Remote Encoding Center in Salt Lake City, Utah, which was the first facility of its kind and is now the last one standing.

Encoding centers peaked in 1997, when the USPS processed 19 billion pieces of difficult-to-read mail using 55 different facilities. But due to advances in computer analysis, as well as the fact that fewer people handwrite letters these days, just one facility dedicated to poor penmanship still operates today. The employees there play a pivotal role in analyzing the 3 million images of garbled addresses they receive each day.

It's a fact

The Hope diamond was sent by U.S. mail from New York to Washington, D.C., on November 8, 1958. It was shipped by jeweler Harry Winston as a donation to the Smithsonian, where it remains on display today. Winston paid $2.44 ($27.35 today) for postage.

Here’s how it works: Before ever reaching the facility, mail is scanned by a computer to determine its destination. While this step is often successful on its own, sometimes the writing is so indecipherable that the address remains a mystery. When that’s the case, an image of the letter is scanned and sent to the encoding facility, where the average employee can rapidly decipher 900 pieces of mail every hour. In some cases, unintelligible letters are brought in for a last-ditch physical inspection, after which mail is either sent on its intended way, returned to sender, or (in rare cases) disposed of.

Today, sharp-tongued verbal jousting primarily exists in the art form known as battle rap, in which two rappers take lyrical aim at each other with intricate (and often devastating) rhymes. During these battles, no insult — artistic or otherwise — is off-limits, and that’s a sentiment that 15th- and early 16th-century Scottish poets might have shared. Medieval Scottish men of words linguistically barbed each other in a practice known as “flyting” (based on the Old English word flītan, meaning “to quarrel”), often as entertainment for the Scottish king and his royal court. The most famous of these “battles” that still survives, known as “The Flyting of Dunbar and Kennedie,” featured Scottish poets William Dunbar and Walter Kennedy entertaining the court of James IV in the early 16th century. Among its many famous attributes, it’s the first recorded moment of scatalogical humor. (One of the more family-friendly examples of its insults, translated from Middle Scots, reads: “Grovel for grace, dog-face, or I shall chase you all winter; Howl and yowl, owl.”)

English is the only official language of Scotland.

While English is the most widely spoken language in Scotland, a bill passed in 2025 gave both Scots and Gaelic official language status alongside English.

The biting lyricism of flyting wasn’t restricted to Scotland, of course. Ancient Irish professional poets, called filid, were also known for their insults, and a form of flyting can be found in Old English literature as well as the famous Norse text the Poetic Edda (in which the trickster god Loki goes on the verbal offensive against his fellow deities). Similar art forms can be found in Japan, Nigeria, parts of the Middle East, and elsewhere. Although flyting didn’t survive the Middle Ages, its influence can be seen in works ranging from Shakespeare to James Joyce. Thankfully, the birth of the rap battle in the 1980s once again provided a much-needed venue for settling serious artistic beef — and it’s been a fixture of hip-hop culture ever since.

“Huh?” is a humble expression, often a near-involuntary linguistic response, but behind this simple interrogatory palindrome is an extraordinary truth — it’s also universal. According to research conducted in 2013 by the Max Planck Institute for Psycholinguistics in the Netherlands, a version of the word can be found in nearly every language on Earth. Researchers analyzed 31 languages, including Spanish, Mandarin, Icelandic, and Indigenous tongues, and what they found was that every one included a word similar in both sound and function to the English “huh?” For example, in Mandarin it’s a?, Spanish e?, Lao a?, and in Dutch he? No matter the language, the word includes a relaxed tongue and rising pitch, and if there’s a sound before the vowel, it’s an “h” or a glottal stop (a consonant sound made by closing the glottis, the space between the vocal folds). Although there is some variation in pronunciation, the word shows staggeringly little difference among languages compared to what might be expected.

Greek is the oldest European language.

Although the Basque region is located in both Spain and France, its native tongue, Euskara — the oldest European language — shares no origins with either language. No one is entirely sure how Euskara, which is still spoken, originated; it’s one of the great linguistic mysteries.

This raises the question: Is “huh?” even a word at all? Perhaps it’s an innate interjection like a scream or a sneeze, or a nonlexical conversational sound like “ummm” or “aaaah.” Yet the researchers noted several factors that point to “huh?” being a full-fledged word. For one, it’s learned (as opposed to animal sounds like grunts), and children don’t use the word until they’ve started speaking. And even languages without an “h” sound still create a close approximation of the word “huh?” The researchers chock this linguistic similarity up to “convergent cultural evolution.” In the animal kingdom, convergent evolution occurs when two animals develop the same traits due to their similar environment (for example, how sharks and dolphins have a similar streamlined look). In a linguistic sense, convergent evolution occurs when pressures in human conversation — like a lack of information that necessitates a need for clarification — create a universal requirement for a word that is quick and easy to pronounce. In time, all languages naturally arrived at more or less the same response to this need: “Huh?”
