Pronounced: LAW-guh-file (alt: LOG-uh-file), noun
Notes: I originally looked at this word hastily and thought that it may be a lover of sawmills or logging… I should have paid closer attention; perhaps you know it?
The word mythomania means “an abnormal tendency to exaggerate or lie”
This word came into English in the early 1900s
Background / Comments
I was right as to origin, but wrong about the meaning. It does comes from the Greek word mythos (myth) combined with mania (excessive enthusiasm or craze). I suppose that someone who loves myths would be tempted to make up their own myths.
