Use the noun magniloquence to describe the way your English teacher speaks, if she has a tendency to use flowery, ornate language to say the simplest things.

Politicians, kings, and actors are all people who might have a tendency toward magniloquence, ornamenting their speech with big words, metaphors, and rhetoric. When someone uses more words than are necessary to get her point across, especially if her tone is pompous or grandiose, she is guilty of magniloquence. The word comes from the Latin magniloquus, "pompous in talk," which combines magnus, "great," and loquus, "speaking."
