Today’s word of the day is mundungus, a stinking tobacco. From the Spanish mondongo, meaning paunch (more precisely, the first stomach of a ruminant), tripe, or black pudding. Walter Skeat has a substantial entry on the word in his Notes on English Etymology. These days, mundungus is mostly known as the first name of the tobacco-smoking Mundungus Fletcher in the Harry Potter young adult fiction by J.K. Rowling.
