Old High German is a member of the Germanic branch of the Indo-Euroepan language family. It is attested from 750-1050 AD, although German words in texts of other languages can be found from the 6th century. Most Old High German texts are religious, often translated from Latin or at least influenced by it. However, it ias not the case of all texts – some are originals, as e.g.  the Hildebrandslied (text of 65 lines) and the Wessobrunn Prayer (poetic text of 12 lines), both from the 9th century AD (with no attested adjective valence).

Examples of adjective valence form other OHG texts are under construction.
