Etymology: "Reheat" is a plain formation: the prefix "re-", meaning "again", attached to "heat". There is nothing hidden in it, and the "heat" half is the older and more interesting one. It descends from Old English "hǣtu", and the prefix traces back through Latin "re-" to an ancient root meaning "back" or "again", which is why the same little syllable turns up in "return", "redo" and "rewind". The prefix is the part that has travelled. Latin "re-" passed into English through Old French "re-", and English speakers have attached it freely to native words ever since, so "reheat" needed no special coinage. It simply joins a productive pattern that English has used for centuries, and the word means exactly what its parts say: to make something hot once more.
