This Week in Words: Current Events Vocab for September 5–September 11, 2026

A yellow boa constrictor named Princess won a role in an upcoming Metropolitan Opera production of Così fan tutte after her successful audition. The opera's staging was inspired by a 1950s Coney Island boardwalk, complete with a snake handler. Princess was among several snakes to try out for the reptilian role, including a smaller brown boa constrictor named Nala, who will be her understudy. Audition is from the Latin auditionem, "a hearing or listening to."

As they examined botanical patterns on shards of ancient Mesopotamian ceramics, researchers found evidence that they represent prehistoric mathematical calculations. Archaeologists looked at thousands of pieces of pots, bowls, and plates decorated with repeating plant designs and concluded that the patterns represented grain, land, and livestock. The number of repetitions was a method of tallying inventory. The Greek root of botanical is botane, "a plant."

By a vote of 164 to one, the U.N. General Assembly agreed to change the way world maps show Africa, switching to one that reflects the continent's true relative size. Instead of using the Mercator projection, which flattens the world and shrinks countries near the equator, an equal-area map projection reflects an African continent that is commensurate with its actual landmass. Africa is 14 times larger than Greenland, a fact that isn't reflected on standard world maps.

Across Texas, halal barbecue is thriving. More than a dozen restaurants have opened or added to their menus in recent years, offering dishes that observant Muslims can eat, using meat that was raised and butchered following specific rules. Several barbecue spots are entirely halal and serve no pork, which is forbidden under Islamic law. The Arabic root of halal means "lawful."

Real estate professionals say the enormous growth of the artificial intelligence industry is contributing to a "mansion shortage" in San Francisco. As AI generates wealth, a growing number of buyers are vying for a limited supply of large, single-family homes. This summer, dozens of houses sold for "at least a million dollars over the asking price," according to one Realtor, and even cash offers on homes that are listed for as much as $25 million are being outbid.

Myanmar's president, Min Aung Hlaing, held talks in Vietnam as part of an effort to normalize relations with other Southeast Asian governments. Ties to the 11 other countries in the Association of Southeast Asian Nations deteriorated after Min Aung Hlaing helped stage a military coup against Aung San Suu Kyi in 2021. Now the Myanmar government hopes to restore diplomacy and an economic relationship with its neighbors.

Some drivers, who call themselves "hypermilers," are going to great lengths to optimize their driving and get the most they can out of every gallon of gas. These drivers maximize their gas mileage by easing into starts and stops, driving smoothly, staying below the speed limit, eschewing air conditioning, and even removing interior parts of their cars to reduce weight. Many hypermilers drive hybrids, and several have set world records for fuel efficiency.

A new study showed that when air quality improves, kids' cognitive development does, too. Researchers tracked a thousand children from 1998 until 2020, during a period when climate policies reduced air pollutants, including some particulates and gases. They found that the toddlers' cognitive test scores were higher from age one to three when their mothers had breathed cleaner air during pregnancy. Pollutant is from a Latin root that means "defile or contaminate."

This year's Asian Games in Japan saw the debut of a controversial form of taekwondo. In this virtual version of the Korean martial art, fighters spar with their typical fast, high-flying kicks and lightning-fast punches, but they never make actual contact with each other. Instead, the competitors' avatars do all the combat on a screen, leading some critics to deride it as "just a video game." The Korean taekwondo translates to "the way of the foot and the fist."

The 2026 Ig Nobel economics prize went to research showing that rich people were more likely to take candy from a child's stash. A series of experiments revealed more unethical behavior among those with the highest incomes, including one in which volunteers were left alone with a candy jar and told it was meant for kids. The wealthiest participants snuck twice as many pieces as the poorest ones. The Ig Nobels celebrate research that "first makes people laugh and then makes them think."
