[*] 204. Faciō , facere , fēcī , factum, make, is regular. But it has imperative fac in the active, and, besides the regular forms, the future perfect faxō, perfect subjunctive faxim. The passive of faciō is—

1. fīō , fiĕrī, factus sum, be made or become.

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

[*] Note.--The forms in brackets are not used in good prose.

[*] a. Most compounds of faciō with prepositions weaken ă to ĭ in the present stem and to ĕ in the supine stem, and are inflected regularly like verbs in -iō:—

1. cōnficiō , cōnficĕre, cōnfēcī , cōnfectum, finish.
2. cōnficior , cōnficī , cōnfectus .

[*] b. Other compounds retain a, and have -fīō in the passive: as, benefaciō , -facere, -fēcī, -factum; passive benefīō, -fierī, -factus, benefit. These retain the accent of the simple verb: as, bene-fă'cis (§ 12. a, Exc.).

[*] c. A few isolated forms of fīo occur in other compounds:—

1. cōnfit, it happens, cōnfīunt; cōnfīat; cōnfieret, cōnfierent; cōnfierī.
2. dēfit, it lacks, dēfīunt; dēfīet; dēfīat; dēfierī.
3. effierī, to be effected.
4. īnfīō, begin (to speak), īnfit .
5. interfīat, let him perish; interfierī, to perish.
6. superfit, it remains over; superfīat, superfierī .
