One who disputes identity of authorship
In ancient Greece, the grammarians who attested the Iliad and Odyssey as to be written by two different authors, rather than the one who was believed to have written it (Homer), were called ‘chorizonts’, stemming from the Greek word khorus, meaning- apart.
Although nowadays we already know that the famous sculpture allegedly portraying Homer, is probably just a random Greek guy; we also know that a poet, an author, named Homer, never really existed but we also know that the Iliad and the Odyssey were surely written by the same person. We just don’t know who he was.
Asides from the Greek Homer incident, another literary confusion occurred between the works of Shakespeare and Bacon and thus this word is very evident in 1800’s sources with its latest appearance in 1887.
Why this word?
How many times a day do you hear one person claiming to have done something, while another person claims to have done that very same thing? In many lines of occupation, it happens on a daily basis. This is a great word, mainly as you can use it around the office and in the faces of chorizonts who prevent hones credit of work, without them knowing what it is that you are talking about.
How to use chorizont?
Although Microsoft Word marks it as misspell and offers anything starting with horizon and going all the way to chorizo (the Spanish hot dog!), the OED offers chorizont, chorizontal, chorizontic and even chorizontist.
A person, an act, a piece of work- all can be chorizontic if depriving a person from being credited for his own work.
