certainとは 意味・読み方・使い方

語源

From Middle English certeyn, certein, certain, borrowed from Old French certain, from a Vulgar Latin unattested form *certānus, extended form of Latin certus (“fixed, resolved, certain”), of the same origin as cretus, past participle of cernere (“to separate, perceive, decide”). Displaced native Middle English wis, iwis (“certain, sure”) (from 古期英語 ġewiss (“certain, sure”)) and alternative Middle English spelling sertane (“some, certain”).
