The compound 'worldwide' is a transparent modern English formation, directly combining two native Old English elements. 'World' originates from the Old English 'woruld', a term which conflated the concepts of human life, age, and the physical earth. 'Wide', from Old English 'wīd', consistently meant broad or far-spreading. The logic of the compound is entirely literal: 'extending across the breadth of the world'. It emerged in the 19th century, reflecting an increasingly interconnected global perspective, where phenomena such as communication, trade, or influence could genuinely be described as spanning the entire planet. The meaning has remained stable, precisely denoting something that is universal or global in its reach.

Structure: world + wide - world: From Old English 'woruld' (the age of man, human existence, the earth), functioning as the core noun root denoting the planet or human society. - wide: From Old English 'wīd' (spacious, extensive), functioning as an adjective/adverb suffix meaning 'extending over a broad area'.
