The word ‘charlatan’ is supposedly derived from the Italian word ciarlare, which means ‘to babble.’
Some of the original charlatans were confidence men who would prey upon people’s misunderstandings about healthcare before modern medicine existed. There used to be traveling medicine shows where the salesperson would make promises of magic elixirs that would heal all wounds. It was only after they had moved on to the next town that people would realize they’d been swindled as these tonics were worthless forms of medicine (this is also where the term snake oil salesman comes from).
A charlatan has also been described as someone who professes to have abilities or expertise that they do not have. The term ‘charlatan’ is perfect for the finance industry because it can attract people pretending — whether they realize it or not — to know more than they actually do.
