round-the-world

The phrase "round-the-world" is a modern English compound adjective formed from three native Germanic elements. "Round" derives from the Old English adjective 'rund' or 'rad', related to a circular course. "World" originates from Old English 'woruld', a compound of 'wer' (man) and 'eld' (age), originally meaning "the age of man" before broadening to mean the Earth and human society. The definite article "the" serves to link and specify the phrase. The literal combination, "round the world", logically describes a journey encircling the globe, a concept that became concretely possible with the age of exploration and later commercial aviation, solidifying its use as a fixed attributive adjective.
