n. a period of 1,000 years
n. a time of great happiness, prosperity, or peace (often capitalized, as in "the Millennium")
The word "millennium" originates from Latin, combining "mille" (meaning "thousand") and "annus" (meaning "year"). The suffix "-ium" was added to form a noun denoting a specific period. Historically, it was used in Christian theology to refer to the prophesied 1,000-year reign of Christ (Revelation 20:1–6), later generalized to any thousand-year span. The morphemes preserve their original Latin spelling, making the term easily analyzable for learners.
