all-world

The compound adjective 'all-world' is a modern English formation built from two foundational Germanic elements. The first, 'all,' descends from the Proto-Germanic allaz, carrying the enduring sense of totality and completeness. The second, 'world,' originates from the Old English woruld, a term which itself combined wer (man) and ald (age), originally denoting "the age of man." The literal combination, "entire age of man," evolved through semantic broadening to mean the entire planet and human civilization. In the 20th century, this transparent compound was adopted into financial jargon, where its literal meaning of "global" was metaphorically refined to signify a select group of top-tier, globally sourced investments, thus blending geographical scope with a qualitative superlative.

Structure: all (entire) + world (planet) - all: From Old English eall, meaning "entire, whole, every." It functions as an adjective modifying the following noun to indicate completeness. - world: From Old English woruld, meaning "human existence, the age of man, the physical universe." It functions as the core noun, specifying the domain or scope.
