different between nuclear vs radiant

English

Etymology

From Latin n??cleus, a contraction of the adjective nuculeus, masculine of feminine nuculea (“pertaining to a small nut”) from nucula + adjectival suffix -eus, -ea, -eum. The Latin nucula + -?ris adds up to nucul?ris, a term that in English becomes nucular; the Latin nuculea + -?ris, becomes Latin nucule?ris (“relative to what pertains to small nut”), later contracted into nuclear. Compare muscle and Latin m?sculus; muscular and m?scul?ris.
