Old Valthungian
Old Valthungian represents a period in the development of the Valthungian language lasting from around 800‒1200 a.d. marked mainly by changes to geminates and intervocalic consonants, as well as the introduction of Germanic ī/j-umlaut and some small but important changes to all of the vowels. Though this is a range which experienced many changes, the most representative example of “Old Valthungian” is the language as it is captured in a few surviving texts believed to date to around 950‒975 a.d.
