Etymology Origin:
The word double traces back to Latin duplus (twofold), combining duo (two) and -plus (fold). It entered English through Old French duble, retaining the core idea of "twice as much" or "twofold." The morphemes dou- and -ble visually and semantically reconstruct the original concept, making it easy to associate with duality or duplication.
