I really enjoy learning about the origins of words and expressions. (I included this in our last list.) Several words now part of ordinary vocabulary started out as proper names.
Charles Ponzi was a con artist who promised investors they would double their money in 90 days.
In the film "La Dolce Vita," directed by Federico Fellini, an intrusive photographer is named Paparazzo.
So there we have four words - boycott, Ponzi scheme, paparazzi, and bowdlerized - that are derived from people's names.
Can you think of any others?
Adjectives like "Orwellian" or "Dickensian" don't count. Those refer to conditions described by an author. "Freudian" doesn't qualify, but if, say, dream interpretation was called sigmundosis, that would count.
