What I learnt last night during University Challenge: the word "malaria" comes from Italian mala (bad) + aria (air). It was thought that this disease was caused by foul air in marshes.
P.S: I don’t watch University Challenge as I can’t stand the humiliation of rarely getting more than one or two answers right. It’s a quiz program where very bright students struggle to answer questions like "What type of object is the end product of a star of less than 4 solar masses?" while the presentator snarls "COME ON Cambridge, it’s obvious!". I was waiting for Nigella Lawson’s new cookery program to start, she’s a lot more pleasant than Jeremy Paxman.
