Etymology

The word "workday" is a straightforward compound of "work" (from Old English weorc, meaning "physical or mental effort") and "day" (from Old English dæg, meaning "24-hour period"). It emerged in Middle English to denote a day designated for labor, contrasting with rest days like weekends or holidays. The logic is transparent: combining "work" and "day" directly reflects its meaning—a day devoted to work.
