Etymologically

facio

Etymology and origin of the Latin word facio

Pronunciation

  • IPA (Classical): [ˈfa.ki.oː][1]
  • IPA (Ecclesiastical): [ˈfaː.t͡ʃi.o][1]

Forms

faciō (present infinitive facere or fāre, perfect active fēcī, supine factum); third (-iō variant) conjugation, suppletive[1]

Etymology

It is inherited from Proto-Italic *fak-i-, from a form of Proto-Indo-European *dʰeh₁- (“to put, place”) extended with *-k-.[2][1] De Vaan takes the -k- to have arisen in the Proto-Indo-European root aorist, as in Ancient Greek ἔθηκα (éthēka, “I put”) and Phrygian αδδακετ (addaket, “he set, placed”); in Italic the stem *fak- (perfect *fēk-) was generalized through the whole verb.[2][3] Its passive is supplied by the unrelated fīō “to become”.[4][1]

Within Italic, compare Oscan fakiiad (“let him make”), Umbrian façia (“let him make”) and Old Latin fhefhaked (“made”) on the Praeneste fibula.[2][4] Further cognate with Sanskrit दधाति (dádhāti, “puts, makes”) and Lithuanian dėti (“to put”).[4]

Earliest recorded meaning

The perfect appears in Old Latin inscriptions, such as feced in the Duenos inscription, and the verb is in the Twelve Tables.[2] The fibula of Praeneste reads Manios med fhefhaked Numasioi “Manius made me for Numerius”.[4]

Semantic evolution

Its range is the widest of any Latin verb: to make or build, to produce by growth, to create, to compose a literary work, and to utter sounds.[4][5] It meant to appoint to an office, to make up or amount to a total, and to spend time.[4] It meant to bring about conditions, actions and agreements, as in bellum facere “to make war” and foedus facere “to make a treaty”, and to acquire money or incur losses.[4][6]

With a clause it meant “to see to it that”, and with a predicate “to render”, as in heredem facere “to make someone heir”; with a genitive of value it meant “to value”, as in magni facere.[4] It meant to do or commit an act, to carry out a duty, to hold a rite, and absolutely to sacrifice.[4] It also meant to suppose or represent, to act or behave, and to be effective.[4]

It survives as French faire, Italian fare and Spanish hacer,[1] and through French it gave English feat and English surfeit, while its participle factum gave English fact.[7]
