Etymology
The word "overbook" is a modern compound verb formed within English. Its first element, "over," is a native English prefix with ancient Proto-Germanic roots, carrying the sense of excess or going beyond a limit. The second element, "book," derives from the Old English noun for a written document, which evolved into a verb meaning to record or register a transaction, such as a reservation. The logical combination of these two morphemes directly creates the specific commercial meaning: to record or reserve beyond the available capacity, a practice common in the travel and hospitality industries to account for potential cancellations.
