The word "full-scale" combines "full" (from Old English full, meaning "complete") and "scale" (from Latin scala, meaning "ladder" or "measure"). Originally used in architecture and engineering to describe 1:1 proportional models, it later broadened to signify comprehensiveness in any context. The logic reflects a progression from literal measurement to metaphorical totality.
