Editing Theodoric (section)

==High and late Middle Ages==
While the Anglo-Saxon name ''Theodric'' (''Deoric'', old form: th = d) became extinct in the Middle English period, it was adopted in Welsh as ''[[Tewdrig]]''.
The name remains popular in medieval German as ''Dietrich'', and is adopted into French as ''Thierry''. It is rendered in [[Medieval Latin]] as ''Theodoricus'' or as ''Theodericus''.
The [[Middle High German]] legend of ''[[Dietrich von Bern]]'' is based on the historical Theodoric, king of the Ostrogoths. The German ''Dietrich von Bern'' is reflected as ''Þiðrekr af Bern'' in the Old Norse ''[[Þiðreks saga]]''. The medieval German legend gives rise to the ''Dietrich'' of the [[German Renaissance|Renaissance era]] ''[[Heldenbücher]]''.
The Old Norse form of the name was Þjóðríkr (spelled þiaurikʀ on the 9th-century [[Rök runestone]]). This became ''Tjodrik'' in [[Middle Norwegian]].

The Dutch form ''[[Derek]]'' was used in England from the 15th century. Similarly, the Scandinavian ''Tjodrik'' is attested for the 12th century, but it is replaced by the Low German forms ''Ditrik, Dirk'' in the late medieval period. The spread of the Low German form to Middle Norwegian, [[Middle Danish]] and late [[Middle English]] or [[Early Modern English]] are part of a larger linguistic trend due to the influence of the [[Hanseatic League]] during this period.
