What does facta mean?
"Facta" is the Latin plural of "factum," meaning a thing done, an act, or a fact. In modern English it survives almost exclusively in formal legal and scholarly contexts, where it denotes the facts or acts underlying a case — the events themselves as opposed to arguments, opinions, or statements about them. A lawyer might distinguish the facta of a dispute from the dicta of earlier rulings, reserving "facta" for what actually happened. Because English already possesses the natural plural "facts," everyday writing almost never calls for "facta"; using it signals deliberate formality or technical precision. The word derives from the Latin verb facere, meaning to do or make — the same root that gives us "factory," "manufacture," and "fact" itself. For readers encountering it in a judgment, treatise, or historical text, "facta" can safely be understood simply as "acts" or "facts," rendered in the learned Latin form that law has preserved for centuries.

- Plural of factum: the facts or acts forming the substance of a matter, especially as distinguished from questions of law or from statements made about them.

In law, everything the parties did is the "facta" — but everything they merely said may be mere "dicta."

Etymology of facta
"Facta" comes from Latin facta, the neuter plural of factum, meaning "a thing done" or "deed," derived from facere, "to do or make." English borrowed the term through legal and scholarly Latin, preserving its Latinate plural alongside words like "dicta" and "acta." Its root facere also produced the native English word "fact" via Old French fait, making "facta" and "facts" etymological siblings with different histories of adoption.
