They probably had different ways of pronouncing some of our syllables and consonants. They would have had words we are not aware of, and different ways of using some of the words we now use. So too, we use words they would not have had. We also think in a different way linguistically. Nevertheless, with a little effort, after a few hours communication would probably be quite free and easy and mutually intelligible.
