nice
/naɪs/·adjective·c. 1300 CE, Middle English, meaning 'foolish, stupid' (attested in the OED from texts of the early 14th century)·Established
Origin
From Latin nescius ('not knowing', from ne- + scire 'to know'), 'nice' entered English in the 1300s meaning 'ignorant' or 'foolish', drifted through 'timid', 'fussy', and 'precise' before settling at 'pleasant' by the 1700s — making it the same root as 'science', a word that stayed sharp while 'nice' forgot what knowing meant.
Definition
Pleasing or agreeable in a general sense; a meaning arrived at through progressive semantic amelioration from Old French 'nice' (foolish, simple), itself from Latin 'nescius' (ignorant), ultimately from PIE *skei- (to cut, split), the root also of 'science'.
The Full Story
Old French / Latinc. 1300, entering Middle English from Anglo-Norman and Old Frenchwell-attested
'Nice' is the textbook example of amelioration in English — one of the most dramatic reversals of meaning in the language. It entered Middle English around 1300 from Old French 'nice', which meant 'foolish, silly, simple, ignorant'. The Old French form derived directly from Latin 'nescius' ('ignorant, not knowing'), a compound of 'ne-' (not) and 'scire' (to know). The verb 'scire' tracesback to the Proto-Indo-European root *skei- (to cut
Did you know?
When you call something 'nice', you are using a word that once meant 'ignorant' — a direct insult. In 13th-century English, a nice person was a fool, someone who didn't knowthings. The Latin source, nescius, is built from ne- ('not') and scire ('to know'). That same scire gives us 'science'. So 'nice' and 'science' share a root: one stayed fixed at the cutting
'foolish, stupid, senseless' — a thoroughly negative quality. By the 14th–15th centuries the word shifted toward 'wanton, lascivious', then 'foolishly particular, fussy, fastidious' — still pejorative but now implying excessive delicacy. By the 16th century it had drifted toward 'precise, careful, requiring exactness', a neutral-to-positive sense used in scholarly and technical contexts. The 18th century saw the final ameliorative leap: 'agreeable, pleasant, kind'. Samuel Johnson noted the word's vagueness in his 1755 Dictionary. Fowler (1926) famously criticised the word as 'a great deal too much work to do', reflecting its semantic overextension. No single coiner is identified; the shift is gradual and attested across Middle and Early Modern English texts. Key roots: *skei- (Proto-Indo-European: "to cut, split, separate; by extension, to discern or distinguish"), scire (Latin: "to know (from the sense of 'to separate one thing from another', i.e. to discern)"), ne- (Latin / Proto-Indo-European *ne-: "negation prefix: not, without").
