Usage notes
3)"Tusentalet"/"Ettusentalet" is often used to refer to the years 1000 to 1099, almost the same period as det elfte seklet ("the eleventh century", which, however, is the years 1001 to 1100). However, the years 1000 to 1099 should, rather than (et)tusentalet, be referred to as tiohundratalet ("the ten hundreds"), to avoid confusion with the period ending with year 1999.
