Did You Know?

We wouldn't lie to you about the history of mythomania. It comes from two ancient roots, the Greek mythos (meaning "myth") and the Late Latinmania (meaning "insanity marked by uncontrolled emotion or excitement"). One myth about mythomania is that it's a very old word; actually, the earliest known uses of the term date only from the beginning of the 20th century. It was predated by a related word, mythomaniac, which appeared around the middle of the 19th century. Mythomaniacinitially referred to someone who was obsessed with or passionate about myths, but it was eventually used for individuals affected with or exhibiting mythomania.
