Why this word is great
PRAECOGNITA — [Noun] Things previously known or which should be known beforehand in order to understand something else. From Latin praecognitus, past participle of praecognoscere ("to foreknow"), from prae- ("before") + cognoscere ("to know"). Unlike "prerequisites" (which frame knowledge as a checklist for entry) or "presuppositions" (which smuggle unexamined beliefs into discourse), praecognita are the silent scaffolding of comprehension—the unspoken axioms upon which meaning is built. It is the weight of a dictionary in your hands before you read a poem, the scent of damp earth before you name it petrichor, or the way a child already knows the shape of hunger before they learn the word. To speak of praecognita is to admit how much we carry before we even begin.
