Hoi polloi is a pejorative term for the public, or the general population (i.e., common folk). The term originates from Greek, and literally means ‘the many’. It is pronounced (hoy pell oy).
This term should not be confused with the phrase hoity toity which is a term used for those who act better than others or haughty.
It is a mass plural noun that does not change form.
Originally it was a good term to mean the majority, rather than the minority. However, in the early nineteenth century it was a term used by the educated to mean the uneducated. It was originally written using Greek letter, so those without a classical education would not understand the characters. It was used by literary giants such as Lord Byron and James Fenimore Cooper.
The term’s popularity seems to have peaked in the 1940s, but has recently made a bit of a comeback.
