cromulent

adj

Etymology: A humorous, intentionally morphologically opaque neologism and nonce word coined by American television writer David X. Cohen for “Lisa the Iconoclast”, a 1996 episode of the animated sitcom The Simpsons. The ending resembles corpulent, temulent and other Latinate adjectives (derived from -ulentus (“full of, abounding in”)).

1. Acceptable, satisfactory, or valid.

   “Mrs. Krabappel: "Embiggens"? I never heard that word before moving to Springfield. Ms. Hoover: I don't know why; it's a perfectly cromulent word. […] Principal Skinner: He's embiggened that role with his cromulent performance.”

   “Nerdcore could rise up, it could get elevated. Oh, and wouldn’t all of those tough rappers hate it if the nerdcore rose up and got elevated. We consider the possibleness of this not overstated. And I know that "possibleness" is not a cromulent word; every syllable injected is intended to be the one you heard (an absurd juxtaposition of mission and goal).”
