nuclear

adj

UK /ˈnjuː.klɪə(ɹ)/ · US /ˈn(j)u.kli.ɚ/

Etymology From Latin nū̆cleus, 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 + -āris adds up to nuculāris, a term that in English becomes nucular; the Latin nuculea + -āris, becomes Latin nuculeāris (“relative to what pertains to small nut”), later contracted into nuclear. By surface analysis, nucleus + -ar. Compare muscle and Latin mūsculus; muscular and mūsculāris.
