Illegitimi non carborundum

Illegitimi non carborundum is a mock-Latin aphorism, often translated as 'Don't let the bastards grind you down'. The phrase itself has no meaning in Latin and can only be mock-translated as a Latin–English pun. The phrase originated during World War II. Lexicographer Eric Partridge attributes it to British army intelligence very early in the war (using the ablative plural illegitimis). The phrase is also used as the first line of one of the extra cod Latin verses added in 1953 to an unofficial school song at Harvard University, "Ten Thousand Men of Harvard". It was later adopted by a number of politicians and figures in potentially stressful positions.
