This Week in Words: Current Events Vocab for February 15–February 21, 2026

The Environmental Protection Agency’s abrogation of the 2009 Endangerment Finding may be the end of clean car regulation in the U.S. The finding stated that greenhouse gases endanger human health, authorizing the EPA to regulate them. After the recent erasure of other regulations limiting auto emissions, the finding was the last rule addressing the efficiency of U.S. vehicles. Environmental groups have sued the EPA over its cancellation.

The women representing the U.S. in Olympic figure skating are refusing to fall into an adversarial relationship with one other. Instead of seeing each other as rivals, Amber Glenn, Alysa Liu, and Isabeau Levito form a close group with the official nickname "Blade Angels." The friends are one of the strongest U.S. women's teams in decades. After the short program on February 17, only Liu remained in the running for the gold medal, but the three continued to be allies, not adversaries.

​​Trend watchers say the side hair part is coming back into fashion, after at least five years dominated by perfectly symmetrical, center-parted hair. Style influencers including Addison Rae, Zoë Kravitz, and Hailey Bieber have switched to an asymmetrical part, along with celebrities such as Zendaya, Sabrina Carpenter, and even U.S. Representative Alexandria Ocasio-Cortez. The return of the uneven, off-center hairstyle is said to represent an interest in softer, old-school glamour.

In a speech at the Munich Security Conference, French President Emmanuel Macron stressed the need for European fortitude. He said that Europe must be bold enough to decrease its reliance on the United States and have the courage to become a "geopolitical power" on its own. Macron argued that Europe also needs to take part in negotiations concerning Ukraine, as well as in future nuclear arms control treaties. The Latin root of fortitude is fortis, "brave."

The Reverend Jesse Jackson, a civil rights leader and politician who galvanized activists and Black political candidates, died at the age of 84. Jackson was an inspiring orator influenced by other civil rights figures, including his mentor, Martin Luther King Jr. Jackson's presidential campaigns, though unsuccessful, motivated generations of Black voters and candidates alike. The figurative meaning of galvanize comes from its original definition, "stimulate by electricity."

A pickleball mixed doubles match in Florida turned into a melee that ended in two arrests. The game turned combative after one player called a "kitchen foul" on the opposing team. The four players exchanged insults, and 63-year-old Anthony Sapienza hit the man on the opposing side with a pickleball paddle. Sixteen bystanders got involved in the brawl. Sapienza and his wife were arrested and charged with battery. Melee's Old French root means "confused fight."

British conservationists are repurposing discarded Christmas trees to save the Lancashire coastline from severe erosion. This month, volunteers planted more than 2,000 trees in the sand of North Beach, St. Anne's. Those trees have already begun to morph into protective dunes, some transforming in just days as the wind quickly covered them with sand. Short for metamorphosis, morph first appeared in the 1980s, when it was used to describe special effects in movies.

China's Lunar New Year holiday season officially began on February 15 and will last for nine days. The Year of the Horse is said to represent optimism and opportunity, and recent speeches by Chinese President Xi have mirrored this message of assurance and positivity. His government also plans to issue $52 million in consumer vouchers this month, coupons meant to encourage spending and boost consumer confidence. The Latin root of optimism means "the best."

Rodent experts are predicting a smaller spring rat population in New York City, thanks to weeks of bitterly cold winter weather. Scientists and officials who oversee city pest complaints say they anticipate at least a slight reduction in the number of rats. Some of the long-tailed, scurrying animals will have succumbed to the cold, while others will simply have had fewer litters of babies. The Latin source of rodent is rodentem, "the gnawers."

For just the fourth time in 140 years, New Jersey's Navesink River froze solid enough for ice yacht teams to compete for the Van Nostrand Cup. In a series of races, the wooden sailboats sped across the ice on steel blades, each steered by two sailors. The Hudson River Ice Yacht Club celebrated its first-ever win against its rival, the North Shrewsbury Ice Boat and Yacht Club. Yacht is from the Middle Low German jaghtschip, or "fast pirate ship."
