Etymology

It is from Latin plēnus (“full”) + -tās.[2][1]

Earliest recorded meaning

Köbler's earliest source is Vitruvius, and Lewis & Short cite his nūbēs propter plēnitātem et gravitātem liquēscunt “clouds dissolve because of their fullness and weight”.[3][4] Köbler dates Vitruvius c. 84–c. 25 BC.[3]

Semantic evolution

It meant fullness to saturation, repletion, and abundance, as in Vitruvius, and Lewis & Short call it post-Augustan.[2][4][5]

It survives as Old French plenté, the source of English plenty (mid-13th century).[1][6]
