About This Root
From Latin facere (to make, do) and its past participle factum. One of the most fundamental roots in English, with variants fec-, fic-, fit-. Produces fact (a thing done), factory (a place for making), manufacture (make by hand), artifact (something made with skill), and factor (one who does/makes). Prefixes create endless combinations: per-fect, de-fect, ef-fect.
