Being called “nice” today feels like a compliment ― if a slightly underwhelming or even backhanded one. But if someone had called you nice 700 years ago, you would have been right to take offense.

Like many words in the English language, “nice” has a rather dramatic origin story, evolving from an outright insult to the more pleasant term we know today. In many ways, its meaning seems to have done a complete 180, and it might even be moving back in the direction it came from.

“Nice comes from the Latin ‘nescius,’ meaning ‘ignorant,’” Sophie Vignoles, a linguist and head of learning content at the language learning app Babbel, told HuffPost. “It entered English by way of French, where it originally meant ‘foolish’ or ‘silly.’ Someone called nice in the 1300s was being insulted, not praised.”

The shift from “ignorant” and “foolish” to “kind” and “agreeable” did not happen overnight.

“It softened in stages over several centuries, moving from foolish to fussy or overly particular, to precise and careful, before settling on pleasant and agreeable by around the 1700s,” Vignoles explained.

Thus, the word nice became what linguists refer to as polysemic ― carrying multiple related meanings, with the correct one changing based on context.

Vignoles and the other experts at Babbel took a closer look at the surprising origin of “nice” as part of its research on the way American English has evolved in honor of the United States’ 250th anniversary this year. In addition to “nice,” they also examined the shifting definitions of “awful,” “gaslight” and “quick.”

The distinctly French journey that “nice” took was particularly interesting to Vignoles. (And no, it does not seem to involve the beautiful city of Nice in France.)

“Babbel’s research found French made up 22% of Webster’s 1828 [English] dictionary and has since grown to 29%, more than any other source language,” she said. “Words like genre and entrepreneur show that influence directly, but nice shows it can also work more quietly, by reshaping the meaning of a word already in use rather than introducing a new one.”

“Nice is a good example of how much of a language’s vocabulary arrives secondhand, filtered through other languages before it settles into its familiar sense,” she added. “In this case, the shift ran from Latin, through French, into the word Americans use every day now.”

This kind of shift in the meaning of a word has happened in many other cases over the past 250 years as well.

“It shows how far a word can travel from its original sense while still staying useful,” Vignoles said. “Nice is one of the clearest examples of a word improving in meaning rather than declining, which is the rarer pattern.”

The pattern is not unique to English, either. She pointed to the Japanese word “yabai,” which used to mean “dangerous” or “risky.”

“Younger speakers have since stretched it to cover almost any strong reaction, good or bad, so it can now mean amazing just as easily as terrible,” Vignoles said. “Like nice, it became more common precisely because its meaning widened, and it shows the same broadening can happen in completely unrelated languages.”

Part of what makes nice so ubiquitous today is precisely what makes it so unsatisfying as a compliment: It means almost everything, which means it risks meaning almost nothing.

There’s some suggestion that nice is so overused now that it could be slowly reverting to its original meaning.

“It has become one of the most reached-for words in everyday English, largely because its meaning has become so broad,” Vignoles said. “Nice can describe weather, a person or an idea, and it always lands as a safe, low-commitment compliment. That flexibility is exactly why it gets used so constantly today.”

The word has become a kind of linguistic Swiss Army knife ― versatile, handy and not particularly impressive in any single application. And that overuse, Vignoles suggested, may be slowly giving nice a new edge.

“There’s some suggestion that nice is so overused now that it could be slowly reverting to its original meaning,” she explained. “You’ll often hear ‘nice’ used as a backhanded compliment, or something one says about someone for whom you have little else to say. Similarly, people commonly receive the compliment ‘nice’ as an insult, interpreting it as if they’ve just been told they have no other interesting qualities, harking back to its original utility.”

So the next time you describe someone or something as “nice,” just remember you’re using a word that started as an insult, passed through several centuries of rehabilitation and landed at a meaning of “pleasant.” But depending on how you use it and your tone of voice, it could mean something bad ― or maybe even nothing at all.
