Etymology: "Oversleep" is a plain English compound: the prefix "over-", meaning beyond a proper or set limit, joined to "sleep". The sense is simple and literal, a matter of sleeping past the time you meant to wake. The prefix descends from Old English "ofer", a word that already meant "above" or "beyond" and shares its ancestry with the modern "over", so the combination adds nothing exotic, only the familiar idea of going past a limit. The prefix is the interesting part. Old English "ofer" traces back through Proto-Germanic to a very old root that also gave Latin "super" and Greek "hyper", which is why "over-" lines up with words like "superb" and "hyperactive" across languages. Since "sleep" was already well established in English, "oversleep" needed no special coinage; it simply names a common mishap with an ordinary, transparent construction.
