The Form of Infinitives

So far you have been exposed to two infinitives (the present active and present passive) and one infinitive use (complementary). There are, in fact, six infinitives and four infinitive uses. Don't worry. Once again you will see that this is mostly stuff you already know, but didn't know you knew!

The six infinitives comprise three tenses and two voices. The tenses are present, perfect, and future; the voices are, of course, active and passive. This matrix should sound familiar. Participles are organized the same way. Infinitives, however, don't leave any blank spaces in their chart.

Take a good look at the forms on this chart and examine the tenses that you have learned.

  • Present active: the second principle part of a verb

  • Present passive: short e changes to an ī

  • Perfect active: pluperfect subjunctive active without personal endings (perfect active stem plus -isse)

  • Perfect passive: pluperfect subjunctive passive without personal endings (perfect passive participle with esse)

  • Future active: future active participle with esse

  • Future passive: supine with ī being the only new form for you to learn in this chapter!)

The future active infinitive usually appears without the esse. It is also important to know that the future active infinitive of sum, futū rus esse, quite often appears as fore. Furthermore, fore is also sometimes used in place of esse, especially in forming the imperfect subjunctive of sum; for example, forem for essem, et cetera.
