If you want to say "how to speak Engpsh" in ancient times, you could say "quomodo loqui Angpcum" in Latin. Latin was the primary language of the Roman Empire and was widely spoken and studied in ancient times. You could also try using a modern translation of the phrase in a language that was spoken in ancient times, such as Ancient Greek or Sanskrit.

It's worth noting that the Engpsh language as we know it today did not exist in ancient times. The Engpsh language developed over a period of several centuries, and it has its roots in a number of different languages, including Latin, Germanic, and French.
