Prefixes are added to a word to change its meaning, and they appear at the front of the word before the base. This is why you commonly see forms like unhappy, redo, or preview, where the prefix sits at the very start and modifies the whole word. The purpose of a prefix is to attach to the beginning to alter meaning, so the most typical position is the front. A suffix, by contrast, goes at the end of a word to add meaning or indicate part of speech (like happiness or moved). An infix would be placed inside the word, which is not standard in English. So the beginning is the correct location for prefixes.
