The word "business" originates from Old English bisignis ("anxiety, care"), derived from bisig ("busy") + the noun-forming suffix -ness. Over time, its meaning shifted from "state of being busy" to "purposeful activity," eventually narrowing to its modern commercial sense by the 14th century. The evolution reflects societal focus on trade and productivity during the Middle Ages.
