When did the English become the preferred language of the royal court and Parliament?
Correct Answer: In 1400
English became the preferred language of the royal court and Parliament in around 1400.
After the Norman Conquest (1066), French became the language of the English ruling class and court. English continued to be spoken by ordinary people, but legal and official business was conducted in French or Latin.
By around 1400, English had re-established itself as the language of the court, partly due to the growth of national identity during the Hundred Years War with France.
