Did you know that Norman Mailer coined the word factoid?
We can thank Norman Mailer for the word factoid; he coined the term in his 1973 book Marilyn, about Marilyn Monroe. In the book, Mailer explains that factoids are "facts which have no existence before appearing in a magazine or newspaper, creations which are not so much lies as a product to manipulate emotion in the Silent Majority." In creating his coinage, Mailer relied on "-oid," a suffix that traces back to the ancient Greek word eidos, meaning "appearance" or "form." Mailer followed in a long tradition when he chose "-oid"; English speakers have been making words from "-oid" since at least the late 16th century.
