What does edacious mean?
Edacious is a formal, literary adjective describing something that eats or consumes voraciously — an appetite marked by greediness and relentlessness. It can apply literally, as in edacious insects stripping a field of crops, or figuratively, as in edacious flames swallowing a building or an edacious intellect devouring books. The word derives from the Latin edax (stem edaci-), meaning 'greedy' or 'devouring,' itself formed on the verb edere, 'to eat' — the same root that gives us edible, comestible, and obese. First appearing in English in the seventeenth century, edacious has never been common; it survives chiefly in elevated prose where writers want a more striking alternative to voracious or ravenous. Its noun form is edacity, meaning voraciousness. Because it is unfamiliar to most readers, edacious works best when context makes its meaning clear, and it lends a deliberately learned, almost ornate tone to descriptions of consumption, destruction, or insatiable desire.

Edacious shares its root with 'edible' and 'obese' — all tracing back to Latin edere, 'to eat'.

Etymology of edacious
Edacious comes from the Latin adjective edax (genitive edacis), meaning 'greedy' or 'devouring,' derived from the verb edere, 'to eat.' English borrowed it in the early seventeenth century, alongside the related noun edacity. It shares its ultimate root with edible, comestible, and obese, which also descend from Latin forms built on edere.
