英和和英

語源

From 中期英語 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 中期英語 wis, iwis (“certain, sure”) (from 古期英語 ġewiss (“certain, sure”)) and alternative 中期英語 spelling sertane (“some, certain”).
