Scholars say that the latest additions, which were announced in September and include terms such as ‘agentic’ and ‘natural language processing’, are notable for the advanced knowledge needed to understand them (see ‘Digital dictionary’).“You can’t really explain ‘vibe coding’ if you don’t know what ‘programming’ is,” says Peter Sokolowski, a lexicographer at Merriam-Webster who writes and edits dictionary entries. He says that the sophistication of the newly listed words reflects non-specialists’ expanded access to highly technical terms, thanks to twenty-first-century digital communication.“This particular batch, more than any other that I’ve seen, really does feel like it’s a meta-commentary on language,” says Sokolowski.Sophisticated wordsFor a word to earn a spot in the Merriam-Webster dictionary, it must first appear repeatedly in mainstream media outlets such as newspapers and magazines, says Sokolowski. Specialist groups of physical- and biological-science ‘definers’ with expertise in these fields identify words that should be added. They then dive deeper into a word’s technical usage to understand its meaning and create a definition targeted at a general audience.Digital dictionaryThe Merriam-Webster dictionary, which traces its roots to a version published in the early nineteenth century, has added a host of technology-related terms.Artificial-intelligence and computing termsAgenticAGI (artificial general intelligence)Compute (as a noun)Natural language processingPrompt engineeringVibe codingOther technical termsBiohackDirect air captureGeoengineeringUncanny valleyThe surging number of complex technical words isn’t surprising, says Lera Boroditsky, a cognitive scientist at the University of California, San Diego, who studies language and cognition. Technological and scientific innovations often drive language change, she says, adding that today’s rate of technological advancement is comparable to, if not greater than, the rate seen during the industrial revolution. That rapid-fire change drives the generation of new words. “The more complex a society becomes, the more of these tightly packed units of meaning we have to make, so we can talk about things that are complex in ways that don't take forever,” she says.Rapid spreaddoi: https://doi.org/10.1038/d41586-026-03044-9SubjectsComputer scienceMachine learningLanguageLatest on:Computer scienceMachine learningLanguageJobs Assistant or Associate Professor of Cell BiologyAssistant or Associate Professor of Cell Biology The Department of Cell Biology at the University of Virginia (UVA) School of Medicine invites appl...Charlottesville, VirginiaUniversity of VirginiaAI ScientistJoin the Casale Group at Human Technopole in Milan to build AI systems that turn human genetics and biomedical data into disease discoveries.Milan (IT)Human Technopole
