We see many symbols in our everyday lives that we likely don’t pay much attention to: the @ in our email addresses, for instance, or the % in our weather forecasts. But do we ever wonder where these symbols came from? Why they look like they do? Or how they came to mean what they mean?

One of the most commonly used symbols that most of us are clueless about is the dollar sign ($). Why does it have an “S” if there’s no “s” in “dollar”? Is there supposed to be one line or two? And where did the $ symbol even originate?

As educator and etymology enthusiast Rob Watts (better known as RobWords on YouTube) explains, the answers to those questions are surprisingly complicated.

The first written use of the dollar sign as we know it appeared in a handwritten letter sent by a man in New Orleans in 1778. Some may be under the impression that the $ is an amalgamation of “U” and “S,” as in United States, but nope. Its origin isn’t actually from the United States at all.

The international origins of the U.S. dollar start in Spain

In fact, we have to take a whole international tour through hundreds of years of currency history to arrive at what we think is the origin of the $. As Watts shares, we don’t know with 100% certainty.

The story begins with the Spanish real, the silver coin that served as the currency of Spain in the 14th century. A larger coin, worth eight times the value of the real, became known as a “piece of eight” in English. Those pieces of eight made their way to the Americas through colonialism in the 15th and 16th centuries.

“The discovery of huge, gleaming reserves of silver in Central and South America meant that they could also be made there, too,” Watts shares. “At the local mints, they took on a new name as well, based on the fixed weights of  silver they were made from. They became known as the ‘peso,’ meaning ‘unit of weight.’”

Because of their reliability and divisibility into smaller units, these pesos started being used not just in the Spanish-speaking colonies, but in British colonies in the Caribbean and North America as well.

Hold the peso thought. We’ll come back to it momentarily.

The word “dollar” can be traced back to the German Joachimsthaler coin

In the meantime, another coin of similar value from the German town of Joachimsthal had gained traction in Europe.

“In precisely the same way that a round slab of beef from Hamburg became known as a hamburger, this round slab of silver from Joachimsthal became known as a Joachimsthaler,” Watts explains. “And in exactly the same way that a hamburger is sometimes just called a ‘burger,’ a Joachimsthaler was sometimes just called a ‘thaler.’”

“Thaler” became “daalder” in the Netherlands, “daler” in parts of Scandinavia, and “dollar” in the English-speaking world.

But that dollar wasn’t the dollar we ended up with.

“By 1700, the thaler had been adapted to have almost exactly the same silver content as another coin that was competing for usage in Europe: the ‘piece of eight’ or peso,” says Watts. “And so, to help differentiate between the two similarly valued coins, people started referring to the peso as ‘the Spanish dollar.’ This Spanish dollar was the de facto currency of the Americas right up until the American Revolution.”

The dollar sign actually comes from the peso symbol

Prior to declaring independence from Britain, the U.S. used the British pound for accounting. But the Spanish dollar, or peso, was the coin most often used as currency, so post-Revolution, the U.S. adopted the dollar as its own. (The first official U.S. dollar coin was minted in 1792.)

So, long story short, the Spanish dollar, or peso, was the basis for the U.S. dollar. Which finally leads us to where the $ came from.

The symbol used for pesos way back when was “ps,” with the “s” written like a superscript. When written with a pen in one stroke, the “s” ended up with a line through it. And when someone wanted to indicate plural pesos, they would write the symbol twice. The second instance, written more quickly, ended up blending the “p” and “s” together to look more like a $.

Essentially, the evolution looked like this:

What about the double-lined dollar sign?

How did the $ with two lines come about? As shown in the image above, the two lines often lead people to the “U” plus “S” theory. However, Watts points out that the first printed version of the dollar sign appeared in 1797. That dollar sign actually had two lines, with no indication that “U” and “S” were the reason. Both versions of the symbol were in use by the close of the 18th century.

Watts goes into some of the other theories about where the double-lined dollar sign comes from. However, there doesn’t seem to be solid evidence to back any of them up.

Isn’t that wild? Who knew that our currency had such a complicated origin story? Or that we don’t even really know for certain why we use $ for the almighty dollar?

While a bottle of bubbles might seem out of place in a hospital setting, you might be surprised to learn that, for thousands of children around the world born with cleft lip and palate, they can be a helpful tool in comprehensive cleft care. Lilia, who was born with cleft lip and palate in 2020, is one of the many patients who received this care. 

As a toddler, Lilia underwent two surgeries to treat cleft lip and palate with Operation Smile’s surgical program in Puebla, Mexico. Because of Operation Smile’s comprehensive care, it wasn’t long before her personality transformed: Lilia went from a quiet and withdrawn toddler to an exuberant, curious explorer, babbling, expressing herself with a variety of sounds, and engaging with others like any child her age. 

Lilia is now a healthy five-year-old, with the same cheerful attitude and boundless energy. Her progress is the result of care at every level, from surgery to speech therapy to ongoing support at home—but it’s also evidence that small, sustained interventions throughout it all can make a meaningful difference. 

Cleft Conditions: A Global Problem

Since 1982, Operation Smile has provided cleft lip and cleft palate surgeries to more than 500,000 patients worldwide with the help of generous volunteers and donors. Cleft conditions are congenital conditions, meaning they are present at birth. With cleft lip and palate, the lip or the roof of the mouth do not form fully during fetal development. Cleft conditions put children at risk for malnutrition and poor weight gain, since their facial structure can make feeding challenging. But cleft conditions can have an enormous social impact as well: Common difficulties with speech can leave kids socially isolated and unable to meet the same developmental milestones as their peers. 

Surgery is a vital step in treating cleft conditions, but it’s also just one part of a much larger solution. Organizations like Operation Smile emphasize the importance of multi-disciplinary teams that provide comprehensive, long-term care to patients across many years. This approach, which includes oral care, speech therapy, nutritional support, and psychosocial care, not only aids in physical recovery from surgery but also helps children develop the skills and confidence to eat easily, speak clearly, and engage in everyday life. This ensures that each patient receives the full range of support they need to thrive. 

A Playful (and Powerful) Solution

Throughout a patient’s care, simple tools like bubbles can play a meaningful role from start to finish. 

Immediately before surgery, children are often in a new and unfamiliar environment far from home, some of them experiencing a hospital setting for the first time. When care providers or loved ones blow bubbles, it’s a simple yet effective technique: Not only are the children soothed and distracted, the bubbles also help create a sense of joy and playfulness that eases their anxiety. 

In speech therapy, bubbles can take on an even more important role. Blowing bubbles requires controlled airflow, as well as the ability to form a rounded “O” shape with the lips, which are skills that children with cleft conditions may struggle to develop. Practicing these skills with bubbles allows children to gently strengthen their facial muscles, improve breath control, and support the motor skills needed for speech development. Beyond that, blowing bubbles can help kids connect with their parents or providers in a way that’s playful, comforting, and accessible even for very young patients. 

Finally, bubbles often follow patients with cleft conditions home in the “smile bags” that each patient receives when the surgical procedure is finished. Smile bags, which help continue speech therapy outside of the hospital setting, can contain language enrichment booklets, a mirror, oxygen tubing, and bubbles. While regular practice with motor skills can help with physical recovery, small acts of play help as well, giving kids space to simply enjoy themselves and join in on what peers are able to do.

Bubbles at Home and Beyond

Today, because of Operation Smile’s dedication to comprehensive cleft care, Lilia is now able to make friends and speak clearly, all things that could have been difficult or impossible before. Instead of a childhood defined by limitation, Lilia—and others around the world—can look forward to a childhood filled with joy, learning, discovery, friends, and new possibilities.

Upworthy has covered a few stories about people who decided to live permanently on cruise ships because it’s cheaper than living on land or in a nursing home. These stories have connected with millions because they say a lot about the modern cost of living but are also aspirational.

Christine Kesteloo has become popular on TikTok with over one million followers because she shares what living on a cruise ship is really like. Kesteloo is the wife of the ship’s Staff Chief Engineer, so she gets to live on the boat for free. She only has to pay for alcohol and soda, which she gets for half off according to Business Insider.

So what is life actually like on board?

“I live on a cruise ship for half the year with my husband, and it’s often as glamorous as it sounds,” she told Business Insider. “After all, I don’t cook, clean, make my bed, do laundry or pay for food.“

Kesteloo’s life seems pretty stress-free. After all, she’s basically on a permanent vacation. However, even though she lives on a cruise ship as a “wife on board,” there are a few things she either can’t or shouldn’t do.

Here are the four things she cannot do

She shared these four things in a TikTok video with nearly 10 million views.

@dutchworld_americangirl I go through four things I can, and cannot do it while living on the cruise ship with my husband #weliveonacruiseship #4things #alaskacruise #cruiseship #cruiseshiplife #cruise #alaska #caribbeancruise #cruiselife #livingstsea #getreadywithme ♬ Chill in a good mood, calm and fun(1263486) – zukisuzuki

Kesteloo says she cannot sit at a slot machine and “play my heart out until I win.” She believes it would “look a little weird if I, as the wife of the staff chief engineer, won a big jackpot.”

2. Leaving the ship with the guests

When the ship arrives at a destination, she can’t get off with the guests. She must wait about an hour and exit the vessel with the crew. When returning to the ship, she also has to be on time. “No, they will not wait for us,” she says. And the same goes for her husband, if they “miss the ship, someone else will take over the role.”

3. Sitting in a crowded pool

Although Kesteloo has access to the pool, gym, and all the ship’s amenities, she’s cautious not to interfere with the guests’ good time. She’ll exit the pool if it’s busy because “it’s just the right thing to do.”

4. Traveling without international traveler insurance

She must have insurance in case of a misfortune on the ship. But as a citizen of the Netherlands, they already have coverage and just have to pay a few extra dollars a month.
