The tag old-german has been used for questions relating to periods as late as the 1920s to 1940s.
However, there are several stages in the history of the German language that have more specific names, e.g.:
- Old High German: roughly 700 to 1050 AD,
- Middle High German: roughly 1050 to 1350 AD,
- Early New High German: roughly 1350 to 1650 (or up to the invention of movable type, according to other periodisations).
The tag old-german currently has no description. What periods do we want it to cover?
