Selected source glosses provide context, not a complete modern definition inventory

From Old French fact, from Latin factum (“an act, deed, feat, etc.”); also Medieval Latin for “state, condition, circumstance”; neuter of factus (“done or made”), perfect passive participle of faciō (“do, make”), ultimately from Proto-Indo-European *dʰeh₁- (“to put, place, set”). Old/Middle French later evolved it into faict and fait. Doublet of feat.

Where this record stops

This page does not supply an independently verified sound-change sequence, first-use manuscript or complete family tree unless a cited analysis explicitly establishes one. Missing detail here is a limit of this record—not a claim that humanity knows nothing more.

An older meaning does not determine what a word must mean today. Follow the sources, preserve disagreements, and keep ancestry separate from interpretation.
