Infinitives

The following is a summary of infinitive forms.  Technically, infinitives do not express time, only aspect, and so the lack of some tenses of the infinitive.  Present infinitives express action occurring at the same time as the main verb, perfect infinitives action before the time of the main verb, and future after the time of the main verb.

 

Present Infinitives
Conjugation Active Passive
First amare amari
Second debere deberi
Third ducere duci
Third -io capere capi
Fourth audire audiri

Note: the present active infinitive form constitutes the second principal part of the verb.
