Summary: Prefixes are key morphemes in English vocabulary that begin words. The English prefix *per-*, which means "through," appears in hundreds of English vocabulary words, such as [*per*]ish and [*per*]son. You can remember that the prefix *per-* means "through" via the word [*per*]manent, for something that is [*per*]manent stays intact "through" the years.
