Origin Story
Nice has undergone the most dramatic shift in meaning of any English word. Latin nescius broke down as ne ("not") + scire ("to know") = "not knowing, ignorant." When it entered English in the 13th century, nice meant "foolish, silly." Over the following centuries its meaning shifted in a long chain: "fussy → meticulous → subtle → refined → pleasant → kind." The crucial turn was from "fastidious" to "able to make fine distinctions (precise)," and from there to the positive "pleasant." By the 18th century, nice had settled into today's sense of "good, kind" — the exact opposite of where it began.
The evolution of nice is the textbook example of amelioration (a meaning rising in status). Its mirror image is villain (originally a "farm laborer") becoming "scoundrel" — a case of pejoration.
