Why is Domesday written in latin?

Answer 1

It was written in latin because it was the most used written language. In an age when virtually the only people who could read and write were priests, who used latin every day, it made sense to write in that language.

Answer 2

The Domesday Book was written in Latin because that was the standard written language for the whole of Western Europe.
In an age when most people could neither read nor write the main centres for education were the churches which, in western Europe, were controlled from Rome, and the Roman Catholic church used Latin as it's main language, written and spoken.
Anyone educated enough would be able to read the Domesday Book whether they were from Normandy or England. If it had been written in Old English no Norman in Williams court would have understood it!

Answer 3

The doomsday book is written in Latin because after William became king french and Latin became the language of all the posh people whereas the peasants still spoke old English (Anglo Saxon)
