I want to know the answer to the following question:
What was Strasbourg known as in the local language in the ninth century?
All the background I'm provided with is that "The town was also called Stratisburgum or Strateburgus in Latin, from which later came Strossburi in Alsatian and Straßburg in Standard German, and then Strasbourg in French.". Is that enough to answer the question?
Answer: no
