Word History

Etymology

borrowed from Latin factum "deed, action, real event," noun derivative from neuter of factus, past participle of facere "to make, bring about, perform, do," going back to a suffixed form *d^hh₁-k-i̯e- (with perfect fēcī from *d^heh₁-k-) of Indo-European *d^hh₁-, d^heh₁- "put, place, make, do" — more at do entry 1

Note: The extension *-k- has been compared with the Greek extended aorist éthēka "I placed" (corresponding to present títhēmi "I set, put, placed"), apparently parallel to Latin jaciō, jacere "to throw" and Greek hêka "I threw" (see jet entry 3); though the identity of the two formatives has been disputed.

First Known Use

15th century, in the meaning defined at sense 4
