Recent large-scale upticks in the use of words like “delve” and “intricate” in certain fields, especially education and academic writing, are attributed to the widespread introduction of LLMs with a chat function, like ChatGPT, that overuses those buzzwords. “The changes we are seeing in spoken language are pretty remarkable, especially when compared to historical trends,” Juzek said. “What stands out is the breadth of change: so many words are showing notable increases over a relatively short period. Given that these are all words typically overused by AI, it seems plausible to conjecture a link.” Words including “surpass,” “boast,” “meticulous,” “strategically,” and “garner” have also seen considerable increases in usage since the release of ChatGPT. While these words are often used in a formal or academic tone, which makes them less common in unscripted, spoken language, researchers found that nearly three-quarters of these target words showed increased usage with some more than doubling in frequency.
