diary: [16] Like its semantic cousin journal, a diary is literally a ‘daily’ record. It comes from Latin diarium, a derivative of diēs ‘day’. Originally in classical Latin the word meant ‘daily allowance of food or pay’, and only subsequently came to be applied to a ‘record of daily events’. From the 17th to the 19th century English also had an adjective diary, from Latin diarius, meaning ‘lasting for one day’.
diary (n.)
1580s, from Latin diarium "daily allowance," later "a journal," neuter of diarius "daily," from dies "day" (see diurnal); also see -ary. Earliest sense was a daily record of events; sense of the book in which such are written is said to be first attested in Ben Jonson's "Volpone" (1605).
