world-class
UK: ˈwɜːld klɑːs | US: ˈwɜːrld klæs
adj. of the highest quality or standard; outstanding in a global context
The term combines "world," derived from Old English weorold (a compound of wer "man" + eld "age," later generalized to mean "the earth or human existence"), with "class," from Latin classis (originally "a division of the Roman people," later "rank or category"). The fusion in the 19th century reflects the rise of international standards, where excellence was measured against global benchmarks rather than local ones. The logic is straightforward: "world" emphasizes scope, while "class" denotes tiered quality.
