Did you know?

Plethora comes from a similar Greek word meaning "fullness." It was first used in English in the 16th century to describe a supposed medical condition marked by an excess volume of blood causing swelling and a reddish complexion. Later, the medical use of "plethora" was extended to indicate related medical conditions (such as an excess volume of bodily fluid or the red-skinned appearance of some newborns). These days, however, "plethora" is more often used in a general, non-medical sense, with the meaning "excess" or "abundance."

Synonyms

Word History

Etymology

borrowed from Late Latin plēthōra, plētūra "fullness, overabundance of a humor," borrowed from Greek plēthṓra (Ionic plēthṓrē) "fullness, crowdedness (of a marketplace at peak hour), excess of a humor or blood," from plēth-, base of plḗthein "to be full" + -ōra, -ōrē, probably dissimilated variant of -ōlē, suffix of deverbal nouns; plḗthein going back to Indo-European *pléh₁-d^h-, extended form of the verbal base *pleh₁- "become full," with *-d^h- marking a completed state — more at full entry 1

Note: The base *pléh₁-d^h- is also evident in Greek plēthȳ́s "great number, multitude, crowd" (compare plebs), plêthos "great number, mass, crowd," plēthȳ́nesthai "to increase in number" (see plethysmograph).
