What is the middle ages language?

Answer 1

We do not know how many languages were used in medieval Europe. Some of the languages used have been lost, and there were undoubtedly a number of them that are not even mentioned in history. The number would have to be in the hundreds, at least.

There were two languages that were very much more important than others, and these were medieval Latin and Greek. Latin was a nearly universal language for the Church, education, and diplomacy in Western Europe, and Greek had a similar importance in parts of the East.

Answer 2

That depends on which country you are in and what specific time period, since languages changed considerably during the very long medieval period.

In England, Old English was spoken up to the mid-12th century by ordinary (non-noble) people, then Middle English began to evolve. Wealthy aristocrats spoke Anglo-Norman French (not the same thing as French). In Germany people spoke Middle High German, in Flanders they spoke Flemish, in Italy many Italian dialects were used, in Spain people spoke Old Spanish. There were many other medieval languages across Europe.

Latin was the language of the Church, of education, of books, legal records, charters, royal decrees and warrants and financial accounts.
