Final answer:
After the Norman Conquest, the few English kings and the new aristocracy primarily spoke French, with Latin being used for scholarly and religious purposes.
Step-by-step explanation:
The language that the few English kings spoke after the Norman Conquest was French. Following the conquest in 1066 by William the Conqueror, a Viking-descended king from Normandy in northern France, the Norman rulers and the new aristocracy primarily used French as their language of governance and daily affairs. This replaced Old English, which was the language of the Anglo-Saxon ruling class before the Norman Conquest. However, Latin continued to be used for scholarly, religious, and some official communications, as it was the language of the educated elite across Europe.
