all-digital

The term "all-digital" is a modern English compound adjective formed in the late 20th century. Its first element, "all," is a fundamental Germanic word of ancient Proto-Indo-European origin, here used as a reinforcing prefix to denote totality. The second element, "digital," traces back to the Latin digitus, initially meaning "finger" or "toe," which became associated with counting. This evolved through "digit" (numerical symbol) to describe technologies that process discrete numerical data. The compound "all-digital" thus logically builds its meaning from "entirely composed of or operating via digital technology," marking a complete shift from earlier analogue systems.

Structure: all (entirely) + digital (using digits) - all: From Old English eall, meaning "entire, whole, every." In this compound, it functions as an intensifying prefix meaning "completely, entirely." - digital: From Latin digitus (finger, toe) via the adjective digitalis. In modern usage, it refers to data represented as discrete digits (numerical values), especially for electronic processing. It functions as the core adjective describing the technological mode.
