How far back in time could we go in the UK before we would start to be unable to understand the English of the day?
Really? So, if we went back to the time of Chaucer, around the 14th century, we would struggle?
Yes, that's likely. Chaucer's English is quite different from Modern English, and it contains many words and spellings that would be unfamiliar to modern speakers. It's possible that we could pick out a few familiar words or phrases, but understanding the text as a whole would be difficult.
