Etymology

edit

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, nucle(us) +‎ -ar = nucle- +‎ -ar. Compare muscle and Latin mūsculus; muscular and mūsculāris.

      Somehow it is much easier to convey the emotions of gayness — the feelings of outsideness —through anthropomorphism. Gay poet and limerist Edward lear uses animals and creatures perfectly this way […] Even the Muppets — as mainstream and heterosexual as some of them may be — are favorites among many gay men […] Look at Mr. Toad in The Wind in the Willows, such a silly, pompous queen, and even Randall Jarrell's The Animal Family has a lot to say about non-human and non-nuclear arrangements.
