facts

Explanation:

Facts can be defined from an ontological point of view, that is, from what exists, and from an epistemological point of view, from what is known, an observable reality. To these dimensions can also be added the communicative dimension.

The word “Fact” derives from the Latin factum, participle of the verb facere, which means to do. “Fact” therefore means events or events that actually happened, referring to their ontological status, not to a proposition.
