journey: [13] Etymologically, a journey is a ‘day’s’ travel. The word comes via Old French jornee from Vulgar Latin *diurnāta. This in turn was derived from Latin diurnum ‘daily allowance or ration’, a noun use of the adjective diurnus ‘daily’, which was based on diēs ‘day’. The specific notion of a ‘day’s’ travel had died out by the mid-16th century, leaving only the more general ‘travel’.

But before going altogether, ‘day’ left its mark on another manifestation of the word journey: the word journeyman ‘qualified worker’ [15]. This has no connection with ‘travelling’; it originally denoted one who was qualified to do a ‘day’s’ work. Another Latin derivative of diurnus was the adjective diurnātis, which has given English diurnal [15], journal [14] (first cousin to diary), and journalism [19]. Sojourn belongs to the same language family.
