The Dutch language has been known under a variety of names. In Middle Dutch, which was a collection of dialects, dietsc was used in Flanders and Brabant, while diets or duutsc was in use in the Northern Netherlands. It derived from the Old Germanic word theudisk, one of the first names ever used for the non-Romance languages of Western Europe, meaning (pertaining to the language) of the people, that is, the native Germanic language. The term was used as opposed to Latin, the non-native language of writing and the Catholic Church. In the first text in which it is found, dating from 784, it refers to the Germanic dialects of Britain. In the Oaths of Strasbourg (842) it appeared as teudisca to refer to the Germanic (Rhenish Franconian) portion of the oath.
What year were the Oaths of Strasbourg written? (If the question is unanswerable, say "unanswerable")
842
