IPA: /prəˈlɛtəriət/
KK: /proʊlɪˈtɛrɪət/
A group of workers who do not own the means of production and must sell their labor to earn a living.
The proletariat played a significant role in the labor movement during the 19th century.
Proletariat → It is derived from the Latin word "proletarius" (meaning belonging to the lowest class of citizens) which comes from "proles" (meaning offspring or progeny). The term originally referred to the class of people who had little wealth and whose only contribution to society was their children. Thus, the word 'proletariat' refers to the working class, particularly in a Marxist context, who do not own the means of production and must sell their labor to survive.
Think of 'proles' meaning offspring, which helps you remember that the proletariat is a class of people whose primary contribution to society is their labor and future generations.
