 like English, for example, or Spanish, is far more primitive and low-level in terms of communication than the way the angels communicate. They communicate pure, direct thoughts. We have to use word symbols in what we speak and what we write. But angels are far above us in that area as well. So I don't want to over-explain it, but according to those who have written widely on this, St. Thomas Aquinas and others, that's the way the angels are. So they don't need to study a language to know how to speak it.
