Heavy Construction

The Allen and Greenough is still under construction; so some links may not work quite the way you would expect.


Fació, facere, fécí, factum, make, is regular. But it has imperative fac in the active, and, besides the regular forms, the future perfect faxó, perfect subjunctive faxim. The passive of fació is -

The present system of fió is regular of the fourth conjugation, but the subjunctive imperfect is fierem, and the infinitive fierí.

a. Most compounds of fació with prepositions weaken a to i in the present stem and to e in the supine stem, and are inflected regularly like verbs in -ió: -


  • cónfició, cónficere, cónfécí, cónfectum, finish.


  • cónficior, cónficí, cónfectus.


b. Other compounds retain a, and have -fió in the passive: as, benefació, -facere, -fécí, -factum; passive benefió, -fierí, -factus, benefit. These retain the accent of the simple verb: as, bene-facis (§ 12. a, Exc.).

c. A few isolated forms of fío occur in other compounds: -


  • cónfit, it happens, cónfíunt; cónfíat; cónfieret, cónfierent; cónfierí.


  • défit, it lacks, défíunt; défíet; défíat; défierí.


  • effierí, to be effected.


  • ínfíó, begin (to speak), ínfit.


  • interfíat, let him perish; interfíerí, to perish.


  • superfit, it remains over; superfiat, superfierí.
