'Slop' chosen as Merriam-Webster's 2025 Word of the Year
US publisher Merriam-Webster has picked out the word "slop" as its 2025 Word of the Year amid an online proliferation of low-quality content generated by artificial intelligence.
While the potential of AI can dazzle and terrify, the growing use of the term slop reflects a recognition that — at least for now — the technology has its limitations.
What does slop mean?
Merriam-Webster says the original sense of the word, from the 1700s, was "soft mud."
By the 1800s, the meaning shifted more to that of food waste, as in "pig slop," and then more generally, "rubbish" or "a product of little or no value."
That sense is now widely applied to AI computer-generated content.
"We define slop as 'digital content of low quality that is produced usually in quantity by means of artificial intelligence,'" said Merriam Webster, the leading US producer of language reference works.
Among the examples of AI slop given by the publisher were:
"People found it annoying, and people ate it up," Merriam Webster said.
Why did Merriam-Webster choose 'slop' as its Word of the Year?
The publisher highlighted the word as a celebration of the fact that, at present, the power of AI is not unlimited.
"In 2025, amid all the talk about AI threats, slop set a tone that's less fearful, more mocking. The word sends a little message to AI: when it comes to replacing human creativity, sometimes you don't seem too superintelligent," it said.
"All that stuff dumped on our screens, captured in just four letters: the English language came through again."
Merriam-Webster's president, Greg Barlow, told the AP news agency that slop was chosen because it's "such an illustrative word."
"It's part of a transformative technology, AI, and it's something that people have found fascinating, annoying and a little bit ridiculous," he said.
