Etymology
The word 'daybook' is a transparent compound formed from two native English roots. 'Day' originates from the Proto-Germanic 'dagaz', which carried the core meaning of the period of daylight. 'Book' descends from Proto-Germanic 'bōks', referring originally to a beechwood tablet used for writing, highlighting the early physical medium of record-keeping. The compound logically combines these elements to denote a record (book) organized by the fundamental unit of daily time (day). This reflects a practical naming convention where the function of an object is described by its primary organizational principle and its physical form.
