What does booked mean?
"Booked" is the past tense and past participle of the verb "to book," meaning to reserve or arrange something in advance — a flight, hotel room, restaurant table, ticket, or appointment. By extension, it works adjectivally: someone who is "booked" has no remaining availability, and "booked solid" vividly conveys a calendar packed with commitments. The word carries practical, everyday connotations of planning and commitment rather than emotion, making it indispensable for discussing travel, hospitality, and professional schedules. In British informal usage, "booked" can also mean having been officially cautioned, whether by a referee brandishing a card or by the police. Its ultimate root is Old English "bōc," related to Germanic words for beech trees, on whose smooth bark early inscriptions were carved — so every time you say you've booked a trip, you're echoing the wooden writing tablets of a thousand years ago.
Reserved or arranged something in advance, such as tickets, lodging, or an appointment.

When a comedian says they're "booked solid," the word traces all the way back to the bōk — the Old English beech tablet that scribes once carved their records into.

Etymology of booked
The verb "book" derives from Old English "bōcian," meaning to grant or assign by charter, itself from "bōc" — the Old English word for book, originally referring to the written tablets or charters on which records were kept. "Bōc" likely traces further back to Germanic roots associated with the beech tree, whose wood was used for carving runic inscriptions. Cognates include German "Buch" (book). The modern reservation sense developed from the practice of recording bookings in ledgers or books.
