“‘To her,’ she would say disparagingly of some silly neighbor, ‘the be-all and end-all is to put on a silver fox and go gallivanting with the hoi polloi.’ Not until I got to college and misused the word myself did I learn that what my mother took to mean the elite-perhaps because ‘hoi polloi’ sounded like another of her disdainful expressions for people who put on airs, ‘the hoity-toity’-actually referred to the masses.”
Philip Roth, My Life as a Man, 1974
Hoi polloi is borrowed from Greek, where it translates literally as “the many.” It entered English in the early 1800s.
