booked

The word 'booked' is a modern English adjective formed from the verb 'book' and the adjectival suffix '-ed'. The verb 'book' evolved from the Old English noun 'bōc', which originally referred to a written document, ledger, or set of wooden tablets. This noun itself has Proto-Germanic origins, linked to the concept of beechwood on which runes were carved. By the 19th century, 'book' had developed the specific verbal sense of 'to enter in a book or register', leading to meanings like making a reservation or recording an official charge. The suffix '-ed' is a productive adjectival marker from Old English, used to denote a state resulting from an action, thus 'booked' literally means 'placed into a register or record', which logically extends to its contemporary senses of having a confirmed reservation or a formal police record.

Structure: book (to reserve/record) + ed (adjective suffix) - book: From Old English 'bōc', meaning a written document or a set of tablets. In this context, it functions as a verb root meaning to record or to reserve. - ed: A suffix of Old English origin, used to form adjectives from verbs, indicating a state or condition resulting from the action.
