Words without sound

Babies can tell you they're hungry before they can say a word: here's how

Imagine trying to order your morning coffee when the barista behind the counter doesn't understand a word or a gesture you're making. That's what many deaf people have to deal with every single day. But awareness is changing things: The more all of us learn about sign language and deaf culture, the more welcoming the world gets. Did you know that concerts have interpreters who convey the words and mood of a performance? Or that babies can sign basic words months before they can speak a single one? Here are 10 things about sign language that will surprise you.

Seen it or not, there’s someone off to the side of the stage, signing along with the music with incredible energy. These folks are sign language interpreters, and their job at live events is to make the whole experience accessible to deaf audience members. They not only translate the words, but they also convey the performance rhythm, mood, and emotion.

Imagine you're at a Rolling Stones concert and you're deaf. Without an interpreter, you'd feel the bass in your chest but miss everything else. With one interpreter, you get the full show.

Hearing babies can learn to sign basic words, even months before they develop the muscle control needed to speak. The fine motor skills required for simple signs develop earlier than the complex coordination needed for speech. "Baby sign language" programs have become popular with hearing parents who want to communicate with their infants before they can talk.

Imagine your 10-month-old signing "more" or "milk" instead of just screaming. Parents who've tried it say it dramatically reduces frustration on both sides, and some research suggests it may actually boost spoken language development.

There is no single, worldwide sign language. American Sign Language (ASL) is completely different from British Sign Language (BSL), even though both countries speak English. And there are hundreds of sign languages across the globe, each one developed naturally within its own deaf community, with its own vocabulary, grammar, and even regional slang.

If you learned ASL fluently and then flew to Japan, you'd be starting from scratch with Japanese Sign Language. A deaf traveler visiting a new country has to navigate a whole new language, just like anyone else.

Back in 1817, a French educator named Laurent Clerc traveled to the United States with Thomas Hopkins Gallaudet to help establish the American School for the Deaf in Hartford, Connecticut. Clerc brought French Sign Language with him, and it blended with the various signing systems already used by American deaf communities: that mix eventually became American Sign Language.

In spoken language, tone of voice tells you whether someone is asking a question or making a statement, whether they're being sarcastic or sincere. In ASL, facial expressions carry that same grammatical weight. Raised eyebrows can signal a yes/no question. A furrowed brow can indicate a "wh-" question, such as "who" or "where." Without the right face, the meaning can change completely.

Imagine signing "You're going to the store?" with a totally flat expression, without indicating if you’re making a statement or asking a question. To a fluent ASL user, that could read as a very different kind of sentence altogether.

In ASL, signers use the space in front of them almost like a stage. You can assign a spot in the air to a person or object, and then refer back to that spot throughout the conversation to mean "he," "she," "it," or "they." It's a pronoun system built entirely out of space and motion.

Picture telling a story about a disagreement between your neighbor and your boss. You'd set up your neighbor on the left side of the signing space and your boss on the right. Then, every time you refer to each of them, you simply point or direct signs toward those spots.

Many people assume sign language is just English translated into hand gestures, but ASL has its own completely independent grammar. The word order and the sentence structure are different, and many concepts that require multiple words in English can be expressed in ASL with a single sign.

If you wanted to say "I gave the book to her" in ASL, the signs, facial expressions, and spatial positioning would work together in a way that has no direct equivalent in an English sentence structure.

Just like spoken English has regional accents (think Boston versus Georgia versus Texas), ASL has regional variations too. The sign for a particular word in New York might look noticeably different from how it's signed in Los Angeles or Atlanta. Historically, schools for the deaf were major hubs where local signing styles developed and were passed down through generations of students.

There are also cultural variations within the deaf community itself. Black ASL, for instance, developed separately during the era of school segregation in the American South and has its own distinct features, signs, and style that differ from mainstream ASL.

Finger-spelling is the system used in ASL to spell out words letter by letter using hand shapes, one shape for each letter of the alphabet. It comes in handy for proper names, technical terms, or any word that doesn't have its own established sign. Fluent ASL users can finger-spell surprisingly fast, and experienced signers can read it just as quickly.

For a long time, scientists assumed that language was processed by the brain purely through sound. Sign language turned that idea on its head. Studies have shown that ASL is processed in the same areas of the brain as spoken languages. The brain, it turns out, is wired for language, not just speech. It doesn't care whether the signal comes through the ears or the eyes.

This means a child who learns ASL from birth shows the same developmental milestones as a child learning a spoken language. And deaf individuals who suffer a stroke affecting the left hemisphere can lose signing ability the same way hearing people lose speech.

Was the forbidden fruit really an apple? 10 Bible surprises

What if some of the Bible stories you grew up with aren't exactly what the Bible says? Was the forbidden fruit really an apple? Were there actually three Wise Men? Did "God helps those who help themselves" really come from the Bible? Over centuries, translations, traditions, and famous works of art have added details that became so familiar, we stopped questioning them. But go back to the texts, and some of these stories look surprisingly different. From Eve's "apple" to the date of Jesus' birth, here are 10 familiar parts of the Bible that may not be quite what we remember.

When you picture the Garden of Eden, what fruit comes to mind? Most people imagine an apple, but there's just one problem: the Bible never says it was an apple.

In the Book of Genesis, the fruit is simply called "the fruit of the tree of the knowledge of good and evil." The original Hebrew text uses the word peri, which simply means "fruit." The apple connection came centuries later, largely through the Latin translation. The Latin word malum can mean both "apple" and "evil," making it an especially fitting symbol for the story. Over time, that association spread through Christian art and literature. Famous works such as Albrecht Dürer’s 1504 engraving Adam and Eve (also known as The Fall of Man) helped cement the image of Eve holding an apple. Today, it's one of the most famous scenes in history, even though the original biblical text doesn’t identify the fruit as an apple at all.

The story of Jesus' birth is so famous that most of us picture the Three Wise Men, sometimes called the Three Kings, standing beside the manger. But the thing is, over the centuries, the story picked up a few details that aren't actually in the Bible.

In the Gospel of Matthew, the only Gospel that mentions these visitors, they are described simply as Magi from the East. The original Greek word, magoi, referred to learned scholars, astrologers, or priests from Persia or Babylon, not kings. But where did the number three come from? Matthew lists three gifts: gold, frankincense, and myrrh, but never says how many visitors brought them. Over the centuries, people naturally assumed there must have been three Magi, one for each gift. Even their familiar names, Melchior, Caspar, and Balthasar, were added later by Christian tradition. So, neither the number of visitors nor their names appears anywhere in the biblical text.

Whether it's used to motivate a friend, encourage a family member, or push yourself to finally make a difficult decision, "God helps those who help themselves" is one of the most familiar religious sayings in America. But here's the surprise: those words never appear in the Bible.

The idea can be traced to ancient Greek sources, including Aesop’s Fables, where the saying appears in an earlier form: "The gods help them that help themselves." The exact modern wording was written by English politician Algernon Sidney in 1698, but it was Benjamin Franklin who helped make it part of American culture when he included it in his 1736 edition of Poor Richard’s Almanack.

Many teenagers have heard "Cleanliness is next to godliness" when it was time to clean their rooms. But despite sounding like a Bible verse, the phrase never appears in Scripture.

The Bible, particularly Leviticus, does contain extensive laws requiring people to wash their bodies and clothes in certain circumstances, especially before religious rituals. But the famous saying itself came much later. In 1605, Francis Bacon wrote in The Advancement of Learning that "cleanness of body" was connected to reverence for God. Then, in 1786, it was Methodist leader John Wesley who used the wording we recognize today in a sermon: "Cleanliness is indeed next to Godliness." Over time, the phrase became a familiar saying that many people simply assumed came from the Bible.

When it comes to famous dates, December 25 may be the most recognizable of all, universally associated with Christmas. But here's the surprising part: the Bible never gives any specific date for Jesus' birth.

The Gospels of Matthew and Luke describe the Nativity but never provide a calendar date, so how did December 25 become Christmas? There are two leading theories. The first is that the Roman Church was celebrating Christmas on December 25 by 336 AD, during Constantine's reign, possibly choosing the date to coincide with existing Roman winter festivals and make it easier to convert the empire to Christianity. The second points to an early Christian tradition that calculated Jesus' birth date from the supposed date of his crucifixion, eventually arriving at December 25.

The story of Jonah and the Whale is so famous that it has appeared literally or symbolically in innumerable works of art and literature, from Michelangelo's Sistine Chapel ceiling (1508-1512) to Herman Melville's 1851 novel Moby-Dick. But there's a small problem with the title we've given it: the Bible doesn’t actually say it was a whale.

In the Old Testament, the original Hebrew text of Jonah 1:17 uses the words dag gadol, meaning "great fish" or "large fish"; it doesn't identify the creature as a whale, or even specify what kind of fish it was. Most modern English translations therefore stick with "great fish," but the familiar "whale" interpretation developed through older translations and later European tradition, eventually becoming so widespread that "Jonah and the Whale" became the name almost everyone recognizes.

Just as we've always pictured the forbidden fruit as an apple, many of us also assume the serpent in the Garden of Eden is the devil himself. But the original story is a little more complicated.

A plain reading of Genesis depicts the creature simply as a serpent or snake, using the Hebrew word nachash. It describes the serpent as clever and crafty, but it never calls it Satan or explicitly identifies it as the devil. So where did the connection come from? The answer comes from later parts of the Bible, particularly the New Testament. In Revelation 12:9 and 20:2, Satan is called "the ancient serpent" (ho ophis ho archaios in Greek), connecting him to the snake of Eden. Over time, Christian tradition applied that later connection back to Genesis, leading to the familiar belief that the serpent was Satan himself.

Many of us remember Samson for his legendary strength and the long hair that was said to be the source of his power. His story with Delilah is one of the Bible's most famous tales of betrayal, but there's one detail some people may have gotten wrong: Delilah didn't actually cut his long hair.

In Judges 16:19, Delilah has Samson's hair shaved while he sleeps on her lap. The text says she called for a man to do the shaving; it never says she did it herself. Yet paintings, films, and other retellings have often shown Delilah wielding the scissors herself, cementing that image in popular culture. It can be considered a small detail, but it’s a great example of how easily familiar Bible stories can pick up elements that aren't actually in the original text.

Many of us think of the Bible as a single book, written at one particular time by one author, or perhaps a handful of them. After all, that's how it looks when you pick one up in a hotel room, but its history is far more complicated.

The Bible is actually a collection of books written by over 40 authors over roughly 1,500 years, from about 1400 BC to AD 100. The exact number of books varies by religious tradition: Protestant Bibles contain 66 books, while Catholic and Orthodox traditions include additional books. Across these different traditions, the writings were produced by kings, prophets, fishermen, and scholars in Hebrew, Aramaic, and Greek. They also span a tremendous range of literary styles, including history, poetry, songs, laws, letters, and prophecy. So while we hold it as one book today, the Bible is actually a collection of many different writings produced across centuries.

Many people assume that at least a few original fragments of the Bible must still exist somewhere. It would be incredible if they did, but none of the original manuscripts, known as autographs, have survived.

The earliest biblical texts were written on fragile materials such as papyrus and animal skins, which could deteriorate through humidity, heat, handling, and simple age. Wars, fires, and other destruction also contributed to their disappearance. So how do we know what the originals said? Through a technique called textual criticism: expert scholars compare thousands of handwritten copies, ancient translations, and quotations from early Christian writers. When they find passages that match across different sources, or differences that reveal how a text changed over time, they can work backward to determine what the original most likely said, even though the original manuscripts themselves are gone.
