From plethoric + -ally (suffix forming adverbs from adjectives). Plethoric is derived from Middle English plectorik (“swollen, plethoric; a swelling, plethora”) [and other forms], from Late Latin plethoricus, plectoricus (“plethoric”), from Koine Greek πληθωρικός (plēthōrikós, “plethoric”), from Ancient Greek πληθώρα (plēthṓra, “plethora”) + -ικός (-ikós, suffix meaning ‘of or pertaining to, in the manner of’, forming adjectives from nouns); πληθώρα (plēthṓra) is from πληθώρη (plēthṓrē, “fullness; generation of blood or humors by the body”) (from πλήθω (plḗthō, “to be or become full, swell”), from Proto-Indo-European *pleh₁- (“to fill”)) + -ᾱ (-ā) (variant of -η (-ē, suffix forming action nouns from verbs)).
