millennia
Many centuries combined
Millennia is the plural of millennium—periods of one thousand years.
The word appears in discussions of deep time: Human civilization spans only a few millennia.
It also describes the singular turning point when one millennium ends and another begins, as with the widely celebrated transition from 1999 to 2000.
