400s
Late Roman Empire
The 400s refers to the fifth century CE (years 400-499) or, in American contexts, a range of numbers in the four hundreds.
In library classification, the 400s denotes the Dewey Decimal section for language and linguistics.
In sports statistics or building addresses, it simply indicates any number from 400 to 499: Her batting average stayed in the 400s all season.
The term follows the pattern of other century designations like the 1800s or 1900s.
