Myth 02Lillian Virginia Mountweazel was a real photographer.
What's true

She never existed. One of the encyclopedia's editors told The New Yorker it was an old tradition to put in a fake entry to protect copyright.

03 · The long read

What it really means

Turn to page 1,850 of the 1975 New Columbia Encyclopedia and you'll find Lillian Virginia Mountweazel: a fountain designer turned photographer, born in Bangs, Ohio, celebrated for her pictures of rural American mailboxes, and killed at 31 in an explosion while on assignment for Combustibles magazine.

None of it is true. She never existed. One of the encyclopedia's editors, Richard Steins, explained to The New Yorker in 2005 that it was an old tradition in encyclopedias to put in a fake entry to protect copyright. If anyone copied Lillian, they'd know where it came from.

Her surname became the name for the whole practice. A mountweazel is a fake entry planted on purpose in a reference work, whether a dictionary, an encyclopedia, a directory or a map. It has no value to readers. Its only job is to be copied, so the copier can be caught.

The word was coined in that 2005 New Yorker piece by Henry Alford. After telling Lillian's story, he went hunting for a rumoured fake word in the New Oxford American Dictionary and called his six suspects "potential Mountweazels". The culprit turned out to be esquivalience, invented by Oxford's editors in 2001. The term caught on: by 2016 a linguistics textbook was using "mountweazel" as an ordinary noun.

A mountweazel is the deliberate relative of the ghost word. A ghost word like dord is born from an accident. A mountweazel is designed, and Lillian's entry hints at its own joke: she died in an explosion while working for a magazine called Combustibles.
