Century

A century means 100 years. The word comes from the word Centuria which is used in Latin America to count certain things or persons to 100. The ordinal number (i.e. second, third, fourth, etc.) used to denote the century will always be one digit higher than the corresponding cardinal digit(s). For example the 17th century consists the years 1600-1699.
