* Europe has many languages: Europe is a continent with a vast and diverse linguistic landscape. It's home to dozens of languages, including Romance languages (French, Spanish, Italian), Germanic languages (English, German, Dutch), Slavic languages (Russian, Polish, Czech), and many more.
* Languages have changed over time: Languages evolve constantly. The languages spoken in Europe today are vastly different from those spoken centuries ago.
To be more specific, we need to know:
* Which period in history are you interested in?
* What part of Europe are you referring to?
For example, if you're interested in the language spoken by ancient Romans, it would be Latin. If you're asking about the language spoken by medieval Germans, it would be a form of Old High German.
Please give me more context so I can provide a more accurate answer!
