Pronunciation

  • Ecclesiastical: [pleˈtɔː.ra][1]

Forms

plēthōra f (genitive plēthōrae); first declension[1] Later manuscripts often have pletura, perhaps by association with plēre “to fill”;[2] plectora appears in a manuscript of Chiron.[2] Medieval spellings include plectora, plectoria and plectorea.[3]

Etymology

It is borrowed from Ancient Greek πληθώρα (plēthṓra, “fullness, satiety”),[1][2][3] from πλήθω (plḗthō, “to be full”).[1][4] Köbler traces it further to Proto-Indo-European *pelh₁- (“to fill”).[4]

Earliest recorded meaning

It is first found in the veterinary writer Pelagonius, as a medical term for a morbid excess of the body's fluids: ne nimia plethora adferat necem, “lest too great a fullness bring death”.[2][4]

Semantic evolution

Chiron speaks of a draught animal fevered by it, and the Mulomedicina of Vegetius uses it too; a medical work ascribed to Soranus explains it as an abundance or repletion of the humours, and the Latin Oribasius uses it of an excess of undigested humours.[2] Glosses render it with plenitudo, “fullness”.[2]

Medieval physicians kept it for a repletion of blood or another humour, often spelled plectora or plectoria.[3] English took it over as a medical word in the 1540s, and the figurative sense “overfullness” is recorded by 1700.[5]
