use of the word carborundum in a pseudo-Latin aphorism "Illegitimi non carborundum", a phrase originated during World War II, which we can render as "don't let despicable persons grind you down". Of course, no use of carborundum as a verb is legitimate Latin, because carborundum is a noun, and not a gerundive of any verb. In any case, after this
