multiplicity

The word 'multiplicity' has a layered history, beginning with the Proto-Indo-European root mel- (strong, great, numerous), which gave rise to the Latin multus (much, many). This combines with plicare (to fold), from PIE plek- (to plait), creating a sense of things being folded or gathered into many layers. The suffix -ity, denoting a state or quality, was then added in Late Latin to form multiplicitas, which described the condition of being manifold. The modern abstract meaning, a large number or variety, retains this core logic of many folds or facets gathered into a complex whole.
