- A decade is a period of 10 years. The word is derived (via French and Latin) from the Ancient Greek dekas which means ten.
Other words for spans of years also come from Latin: biennium, triennium, quadrennium, quinquennium (5 years), lustrum (5 years), century (100 years), millennium (1000 years).
