proletarian: [17] A Roman citizen of the lowest class was termed a prōlētārius. The only service he was capable of performing for the state was that of producing children, to maintain its population level, and it was this function that gave the prōlētārius his name. For it was derived from prōlēs ‘offspring’, a word based on the same source (*ol- ‘nourish’) as produced English adolescent, alimony, etc.

The abbreviation prole dates back to the late 19th century (George Bernard Shaw is the first writer on record as using it), but it was George Orwell in the 1930s who firmly established the term. The immediate source of proletariat [19] is French prolétariat (in the 19th century it was often anglicized to proletariate). English is also indebted to Latin prōlēs for prolific [17], which comes from the medieval Latin derivative prōlificus ‘producing offspring’.
