English[edit]

Etymology[edit]

From L, nucleus, a contraction of the adj. nuculeus, masc. of fem. nuculea ( "pertaning to a small nut") from L, nucula + adjectival suffix -eus;-ea;-eum. The L, nucula + -aris adds up to L, nucularis, a term that in English becomes nucular; the L, nuculea + -aris, becomes L, nuculearis ("relative to what pertains to small nut") , later contracted into nuclear. Compare muscle and L, musculus; muscular and muscularis.
