Etymology

Origin of flaccid

First recorded in 1620–30; from Latin flaccidus “flabby, drooping,” equivalent to flacc(ēre) “to grow weak, languish” + -idus -id 4

Explanation

If something is limp, loose, droopy, and wrinkly, you can call it flaccid, which rhymes with "acid." Think elephant skin, soggy asparagus, and the type of feeble handshakes frowned on in job interviews. We get the word flaccid from the Latin flaccus, which meant "flabby." The meaning is pretty much the same today, though it applies to more than physical flab. Flaccid pops up in conversation to describe lackluster leadership, dull conversation, and even feeble attempts at word definitions. If a politician's election campaign is flaccid, it will surprise no one that he only receives two votes — one from his grandmother and the other from someone who accidentally checked the wrong box on the ballot.
