Etymology: "Prefill" is a plain compound: the prefix "pre-", meaning "before," attached to "fill." The word "fill" descends from Old English "fyllan," a verb meaning to make full, which traces back through Proto-Germanic "fullijaną" to an adjective "fullaz," meaning "full." So the core of the word is a very old Germanic idea of making something full, and the prefix simply adds the sense of doing this in advance. The prefix "pre-" comes from Latin "prae," meaning "before" or "in front of," and reached English through Middle English. It appears in many familiar formations such as "preview," "prepay," and "preheat," where the same logic applies: an action completed before some later step.
