Establishing charter of the abbey of Tihany

The establishing charter of the abbey of Tihany is a document known for including the oldest written words in the Hungarian language.

The document, dated to 1055, lists the lands the king donated to the newly founded Tihany Abbey.

The Benedictine abbey of Tihany was founded by King Andrew I and was dedicated to the Virgin Mary and Aignan of Orleans.

The longest of these, & feheruuaru rea meneh hodu utu rea clearly shows a language stage in which the -ra suffix (-re after front vowels) has not yet evolved into a suffix from a postposition, and in which the final vowels are still preserved (compare 'Feheruuaru' with modern 'Fehérvár' and 'utu' with modern 'út' – don't pay attention to the diacritics as in 1055 Hungarian spelling was not yet developed to show the a/á and u/ú difference, although they must have existed in pronunciation).

In total, the document includes 58 Hungarian words, among them Tichon, an early spelling of the name Tihany.
