Let’s face it, the Roman Empire was a big place. As you travel away from the city of Rome, toward the frontiers of the Empire, people were less fussy about speaking Latin. Those regions had had their own native languages before Julius Caesar showed up. They adopted Latin and its grammar as it suited them. They mixed it in with the language they’d already been speaking.
