What does edacity mean?
Edacity is a rare and formal English noun meaning extreme voracity — an intense, often insatiable appetite for food. By extension it can describe a ravenous eagerness for anything consumed eagerly, such as knowledge, reading, or experience. The word derives from the Latin edax (genitive edacis), meaning 'greedy' or 'devouring', itself formed on the verb edere, 'to eat', which also gives us 'edible'. First recorded in English in the early seventeenth century, edacity has never been common, and modern usage tends to favor near-synonyms like voracity or greediness. When it does appear, it is usually in literary or deliberately ornate writing, where its Latinate precision lends weight to descriptions of hunger — whether literal gluttony or metaphorical devouring of books, ideas, or opportunities. Its adjective form is edacious.
Extreme voracity or greediness in eating; insatiable appetite.
"The feast was devoured with an edacity that astonished their hosts."
Rare and literary; 'voracity' is the usual modern choice.
An intense eagerness or ravenous desire for something, especially knowledge or experience.
"He pursued every lecture in the city with tireless edacity."
The plural is rare since edacity typically denotes an uncountable quality; it appears only when referring to distinct instances or kinds of voracity.
"The memoir catalogues the edacities of his youth — for food, for fame, for books."
Edacity shares its ancient root with 'obese' — the Romans built both words on the simple act of eating.

Etymology of edacity
Edacity comes from the Latin edax, edacis, meaning 'greedy' or 'devouring', derived from the verb edere, 'to eat', plus the noun-forming suffix -itas, which became English '-ity'. It entered English in the early seventeenth century as part of the era's wave of Latinate learned borrowings. The same root ed- underlies 'edible' and, through Vulgar Latin, 'obese'.
