The first part of my story of English concluded with the coming of the Normans, and a story from the 12th century sums up what happened after the Normans settled. A local priest witnessed a miracle, where after the laying on of hands, a mute man was cured and able to speak English and French. The priest was resentful. Brother William, he said, had laid hands on this man and instantly he could speak two languages, whereas he, the local priest, had to remain dumb in the presence of the bishop. This priest, it transpired, knew little Latin, and no French.
In 1154, the English monks who had written the Anglo-Saxon Chronicle (established by Alfred the great) put down their pens. French was the language to speak, and Latin was used for writing and remained the principal language of religion and learning. A visitor from another planet would assume that English disappeared, to be replaced permanently by French.
However, we know this is not so.
